CSS Style Sheet
• CSS saves a lot of work
• It defines how HTML
elements are to be displayed
• They are normally saved in
external .css files
• External style sheets enable
you to change the appearance
and layout of all the pages in a
Web site, just by editing one
single file

CSS Syntax
A CSS rule set consists of a selector and a declaration block:
• The selector points to the HTML element you want to style.
• The declaration block contains one or more declarations separated by
semicolons.
• Each declaration includes a property name and a value, separated by a colon.

CSS Example
• A CSS declaration always ends with a semicolon, and declaration groups
are surrounded by curly brackets:
p {color:red;text-align:center;}
<!DOCTYPE html>
<html>
<head>
<style>
p {color:red; text-align:center;}
</style>
</head>
<body>
<p> Hello..!!</p>
<p> Welcome to IEI..</p>
</body>
</html>
Code:
Output:

CSS Comment
• Comments are used to explain your code.
• It may help you when you edit the source code at a later date.
• Comments are ignored by browsers.
• A CSS comment starts with /* and ends with */.
Example :
/*This is a multiple
lines comment*/
p
{
color:red;
/*This is another comment*/
text-align:center;
}

CSS Selectors
• CSS selectors allow you to select and manipulate HTML
element(s).
• CSS selectors are used to "find" (or select) HTML elements
based on their :
– Id
– Classes
– Types
– Attributes
– values of attributes and much more.

The element selector
• The element selector selects elements based on the element name.
• You can select all <p> elements on a page like this: (all <p> elements
will be center-aligned, with a red text color)
<!DOCTYPE html>
<html>
<head>
<style>
p {color:red; text-align:center;}
</style>
</head>
<body>
<p> Hello..!!</p>
<p> Lampang, Thailand..</p>
</body>
</html>
Code:
Output:

The id Selector
• The id selector uses the id attribute of an HTML tag to find the
specific element.
• An id should be unique within a page, so you should use the id
selector when you want to find a single, unique element.
• To find an element with a specific id, write a hash character, followed
by the id of the element.
• The style rule below will be applied to the HTML element with
id="para1":

The id Selector
Code:
Output:
<!DOCTYPE html>
<html>
<head>
<style>
#para1 {color:red; text-align:center;}
</style>
</head>
<body>
<p id="para1"> Hello..!!</p>
</body>
</html>

The Class Selector
• The class selector finds elements with the specific class.
• The class selector uses the HTML class attribute.
• To find elements with a specific class, write a period character,
followed by the name of the class:
• In the example below, all HTML elements with class="center" will be
center-aligned:

The Class Selector
<!DOCTYPE html>
<html>
<head>
<style>
.center {color:red; text-align:center;}
</style>
</head>
<body>
<h1 class="center"> LCCT </h1>
<p class="center"> Hello..!!</p>
</body>
</html>
Code:
Output:

Grouping Selector
• In style sheets there are often elements with the same style.
• To minimize the code, you can group selectors.
• To group selectors, separate each selector with a comma.

Grouping Selector
Code:
Output:<!DOCTYPE html>
<html>
<head>
<style>
h1,h2,p {color:red; text-align:center;}
</style>
</head>
<body>
<h1> LCCT </h1>
<h2 > Hello..!!</h2>
</body>
</html>

CSS How To .. ??
• There are three ways of inserting a style sheet:
– External style sheet
– Internal style sheet
– Inline style

External Style Sheet
• An external style sheet is ideal when the style is applied to many pages.
• With an external style sheet, you can change the look of an entire Web site
by changing one file.
• Each page must link to the style sheet using the <link> tag. The <link> tag
goes inside the head section.
• An external style sheet can be written in any text editor.
• The file should not contain any html tags.
• The style sheet should be saved with a .css extension.

External Style Sheet
Example:
Create a CSS file save as, external.css
h1 {color:sienna;}
h2 {color:blue;}
p {color:red;}
Create a html file save as, External.html
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css"
href="external.css">
</head>
<body>
<h1> LCCT </h1>
<h2 > Hello..!!</h2>
</body>
</html>
OUTPUT:

Internal Style Sheet
• An internal style sheet should be used when a single document has a
unique style.
• We define internal styles in the head section of an HTML page, by using the
<style> tag.
<!DOCTYPE html>
<html>
<head>
<style>
p {color:red;}
</style>
</head>
<body>
<p> International Education Institute</p>
</body>
</html>
Example: OUTPUT:

Inline Styles
• To use inline styles you use the style attribute in the relevant tag.
• The style attribute can contain any CSS property.
<!DOCTYPE html>
<html>
<body>
<p> International Education Institute</p>
<p style="color:blue";>Lampang Thailand</p>
</body>
</html>
Example:
OUTPUT:

CSS Background
• The background-color property specifies the background color of an
element.
• The background color of a page is defined in the body selector.
<!DOCTYPE html>
<html>
<head>
<style>
body {background-color:#ffff00;}</style>
</head>
<body>
<h3>International Education Institute</h3>
<p>Lampang Thailand</p>
</body>
</html>
Example 1: OUTPUT:

CSS Background
<!DOCTYPE html>
<html>
<head>
<style> h1{background-color:#ffff00;}</style>
<style> h3{background-color:#ff0022;}</style>
<style> div{background-color:#ffff77;}</style>
<style> p{background-color:#ffff33;}</style>
</head>
<body>
<h1> LCCT</h1>
<div>

</body>
</html>
Example 2:
OUTPUT:

CSS Background Image
<!DOCTYPE html>
<html>
<head>
<style>
body {background-image:url("background1.jpg");}
</style>
</head>
<body>
<h1> Hello</h1>
</body>
</html>
Example: OUTPUT:
Note: Save an image as background1.jpg in the same folder as the html file

Background Image
Repeat Horizontally or Vertically
<!DOCTYPE html>
<html>
<head>
<style>
body {background-image:url("background3.jpg");}
</style>
</head>
<body>
<h1> Hello</h1>
</body>
</html>
Example: OUTPUT:
By default, the background-image property repeats an image both horizontally and vertically.
Some images should be repeated only horizontally or vertically, or they will look strange, like this:

Background Image
Repeat Horizontally or Vertically
<!DOCTYPE html>
<html>
<head>
<style>
body {background-image:url("background3.jpg");
background-repeat:repeat-x;}
</style>
</head>
<body>
<h1> Hello</h1>
</body>
</html>
Example: OUTPUT:
If the image is repeated only horizontally (repeat-x), the background will look better:

Background Image
Set position and no-repeat
<!DOCTYPE html>
<html>
<head>
<style>
body
{background-image:url("Web.png");
background-repeat:no-repeat;}
</style>
</head>
<body>
<h1> Hello</h1>
</body>
</html>
Example: OUTPUT:
Note: Save an image as Web.png in the same folder as the html file

CSS Font
• CSS font properties define the font family, boldness, size, and the style of a
text.
• In CSS, there are two types of font family names:
– generic family - a group of font families with a similar look (like "Serif" or "Monospace")
– font family - a specific font family (like "Times New Roman" or "Arial")

CSS Font
Example: Output:
<!DOCTYPE html>
<html>
<head>
<style>
p.serif {font-family:"Times New Roman", Times, Serif;}
p.sansserif {font-family:Arial, Helvetica, sans-serif;}
p.monospace {font-family:"Courier New","Lucida Console";}
</style>
</head>

<p class="sansserif"> International Education Institute</p>
<p class="monospace"> Lampang, Thailand</p>
</body>
</html>

CSS Font Style
• The font-style property is mostly used to specify italic text.
• This property has three values:
– normal - The text is shown normally
– italic - The text is shown in italics
– oblique - The text is "leaning" (oblique is very similar to italic, but less supported)
<!DOCTYPE html>

CSS Links
• Links can be styled with any CSS property (e.g. color, font-family, background, etc.).
• In addition, links can be styled differently depending on what state they are in.
• The four links states are:
– a:link - a normal, unvisited link
– a:visited - a link the user has visited
– a:hover - a link when the user mouses over it
– a:active - a link the moment it is clicked
<!DOCTYPE html>
<html>
<head>
<style>
a:link {color:#FF0000;} /*unvisited link*/
a:visited {color:#00FF00;} /*visited link*/
a:hover {color:#FF00FF;} /*mouse over link*/
a:active {color:#0000FF;} /*selected link*/
</style>
</head>
<body>
<p><a href="http://www.lcct.ac.th" target="_blank"> Visit LCCT Website </a></p>
</body>
</html>
Example:

CSS Links – Text Decoration
• The text-decoration property is mostly used to remove underlines from links:
<!DOCTYPE html>
<html>
<head>
<style>
a:link {text-decoration: none;} /*unvisited link*/
a:visited {text-decoration:none;} /*visited link*/
a:hover {text-decoration:underline;} /*mouse over link*/
a:active {text-decoration:underline;} /*selected link*/
</style>
</head>
<body>
</body>
</html>
Example:

CSS Links – Background Color

<!DOCTYPE html>
<html>
<head>
<style>
a:link {background-color:#FFFFFF;} /*unvisited link*/
a:visited {background-color:#FFFF85;} /*visited link*/
a:hover {background-color:#FF704D;} /*mouse over link*/

Example Part II

CSS Tables
• The look of an HTML table can be greatly improved with CSS:
Example:

CSS Table Borders
• To specify table borders in CSS, use the border property.
• The example below specifies a black border for table, th, and td elements:
Example: <!DOCTYPE html>
<html>
<head>
<style>
table,th,td {border: 1px solid black;}
</style>
</head>
<body>
<table>
<tr>
<th>Name</th>
<th>Age</th>
</tr>
<tr>
<td>Maliwan</td>
<td>16</td>
</tr>
<tr>
<td>Saengduan</td>
<td>17</td>
</tr>
</table>
</body>
</html>
Output:

CSS Border Collapse
• The border-collapse property sets whether the table borders are collapsed into a
single border or separated:
Example:
<!DOCTYPE html>
<html>
<head>
<style>
table{border-collapse:collapse;}
</style>
</head>
<body>
<table>
<tr>
<th>Name</th>
<th>Age</th>
</tr>
<tr>
<td>Maliwan</td>
<td>16</td>
</tr>
<tr>
<td>Saengduan</td>
<td>17</td>
</tr>
</table>
</body>
</html>
Output:

Table Width & Height
• Width and height of a table is defined by the width and height
properties.
• The example below sets the width of the table to 100%, and the
height of the th elements to 50px:
Output:

Table Width & Height
Code:
<!DOCTYPE html>
<html>
<head>
<style>

<tr>
<td>Maliwan</td>
<td>16</td>
<td>Lampang</td>
</tr>
<tr>
<td>Saengduan</td>
<td>17</td>
<td>Chiangmai</td>
</tr>
</table>
</body>
</html>

Text Alignment
• The text-align property sets the horizontal alignment, like left, right, or center:
Output:
<!DOCTYPE html>
<html>
<head>
<style>
td {text-align: center;}
</style>
</head>
<body>
<table>
<tr>
<th>Name</th>
<th>Age</th>
<th>Address</th>

<td>16</td>
<td>Lampang</td>
</tr>
<tr>
<td>Saengduan</td>
<td>17</td>
<td>Chiangmai</td>
</tr>
</table>
</body>
</html>

Table Padding
• To control the space between the border and content in a table, use the
padding property on td and th elements:
Output:
Example:
<!DOCTYPE html>
<html>
<head>
<style>
td {padding:15px;}
</style>
</head>
<body>
<table>

CSS Box Model
• All HTML elements can be considered as boxes. In CSS, the term "box model" is used
when talking about design and layout.
• The CSS box model is essentially a box that wraps around HTML elements, and it
consists of: margins, borders, padding, and the actual content.
• The box model allows us to place a border around elements and space elements in
relation to other elements.
• The image below illustrates the box model:

CSS Box Model
Explanation of the different parts:
• Margin - Clears an area around the border. The margin does not have a
background color, it is completely transparent
• Border - A border that goes around the padding and content. The border is
inherited from the color property of the box
• Padding - Clears an area around the content. The padding is affected by the
background color of the box
• Content - The content of the box, where text and images appear
The total width of the element in the example is 300px:
width:250px;
padding:10px;
border:5px solid gray;
margin:10px;
Let's do the math:
250px (width)
+ 20px (left + right padding)
+ 10px (left + right border)
+ 20px (left + right margin)
= 300px

CSS Box Model
• Assume that we have only 250px of space. Let's make an element with a total
width of 250px:
Code:
<!DOCTYPE html>
<html>
<head>
<style>
div.example
{ width:220px;
padding: 10px;
border:5px solid red;
margin:0;}
</style>

CSS Outline
• An outline is a line that is drawn around elements (outside the borders) to
make the element "stand out".
• However, the outline property is different from the border property.
• The outline is not a part of an element's dimensions; the element's total
width and height is not affected by the width of the outline.

CSS Outline
Example:
<!DOCTYPE html>
<html>
<head>
<style>
p
{
outline:3px solid green;

CSS Display & Visibility
• Hiding an element can be done by setting the display property to "none" or the
visibility property to "hidden".
• Visibility:hidden hides an element, but it will still take up the same space as before.
The element will be hidden, but still affect the layout.
• Display:none hides an element, and it will not take up any space. The element will
be hidden, and the page will be displayed as if the element is not there.
Example
Output
<!DOCTYPE html>
<html>
<head>
<style>
h4.display_none{display:none;}

CSS Display – Block & Inline Element
• A block element is an element that takes up the full width available, and has
a line break before and after it.
• Examples of block elements:
– <h1>
– <p>
– <div>
• An inline element only takes up as much width as necessary, and does not
force line breaks.
• Examples of inline elements:
– <span>
– <a>

• Changing How an Element is Displayed
• Changing an inline element to a block element, or vice versa, can be useful for
making the page look a specific way, and still follow web standards.
Example: Display Inline
<!DOCTYPE html>
<html>
<head>
<style>
li{display:inline;}
</style>
</head>
<body>
<p> Display the link list as horizontal menu </p>
<ul>
<li><a href="http://www.google.com" target="_blank">GOOGLE</a></li>
<li><a href="http://www.hotmail.com" target="_blank">HOTMAIL</a></li>

CSS Positioning
• The CSS positioning properties allow you to position an element. It can also place an
element behind another, and specify what should happen when an element's
content is too big.
• Elements can be positioned using the top, bottom, left, and right properties.
However, these properties will not work unless the position property is set first.
They also work differently depending on the positioning method.
• There are four different positioning methods.
– Static Positioning
• HTML elements are positioned static by default.
– Fixed Positioning
• An element with fixed position is positioned relative to the browser window.
– Relative Positioning
• A relative positioned element is positioned relative to its normal position.
– Absolute Positioning
• An absolute position element is positioned relative to the first parent element that has a position
other than static.

CSS Fixed Positioning

CSS Float
• With CSS float, an element can be pushed to the left or right, allowing other
elements to wrap around it.
• Float is very often used for images, but it is also useful when working with layouts.
• Elements are floated horizontally, this means that an element can only be floated left
or right, not up or down.
Example If an image is floated to the right, a following text flows around it, to the left:

CSS Float
Code
<!DOCTYPE html>
<html>
<head>
<style>
img { float:right;}
</style>
</head>
<body>
<h4> This is an example of Image with style Float:Right </h4>

Aligning Block Elements
Center Aligning Using the margin Property
• Block elements can be center-aligned by setting the left and right
margins to "auto".
• Using margin:auto; will not work in IE8 and earlier, unless a !DOCTYPE
is declared.
• Center alignment has no effect is the width is 100%.

Crossbrowser Compatibility Issues
• When aligning elements like this, it is always a good idea to predefine
margin and padding for the <body> element. This is to avoid visual
differences in different browsers.

CSS Combinators
• A combinator is something that explains the relationship between the
selectors.
• A CSS selector can contain more than one simple selector. Between the
simple selectors, we can include a combinator.
• There are four different combinators in CSS3:
– descendant selector
– child selector
– adjacent sibling selector
– general sibling selector

Descendant Selector
• The descendant selector matches all element that are descendants of a specified
element.
• The following example selects all <p> elements inside <div> elements:
<!DOCTYPE html>
<html>
<head>
<style>
div p
{
background-color:yellow;
}
</style>
</head>
<body>
<div>
<p>Paragraph1 in the div</p>
</div>
<p>Paragraph3 outside the div</p>
</body>
</html>
Output

Child Selector
• The child selector selects all elements that are the immediate children of a specified
element.
• The following example selects all <p> elements that are immediate children of a
<div> element:
Output
<!DOCTYPE html>
<html>
<head>
<style>
div>p
{
}
</style>
</head>
<body>
<div>
</div>
</body>
</html>

Adjacent Sibling Selector
• The adjacent sibling selector selects all elements that are the adjacent siblings of a specified
element.
• Sibling elements must have the same parent element, and "adjacent" means "immediately
following".
• The following example selects all <p> elements that are placed immediately after <div>
elements:
Output
<!DOCTYPE html>
<html>
<head>
<style>
div+p
{
}
</style>
</head>
<body>
<div>
</div>
</body>
</html>

General Sibling Selector
• The general sibling selector selects all elements that are siblings of a specified element.
• The following example selects all <p> elements that are siblings of <div> elements:
Output
<!DOCTYPE html>
<html>
<head>
<style>
div~p
{
}
</style>
</head>
<body>
<div>
</div>
</body>
</html>

CSS Pseudo-classes
• CSS pseudo-classes are used to add special effects to some selectors.
• Syntax
• The syntax of pseudo-classes:
– selector:pseudo-class {property:value;}
• CSS classes can also be used with pseudo-classes:
– selector.class:pseudo-class {property:value;}
• Types of Pseudo-classes
– The :first-child Pseudo-class
– The :lang Pseudo-class
– The :focus pseudo-class

CSS The :first-child Pseudo-class
Example - I
<!DOCTYPE html>
<html>
<head>
<style>

CSS Navigation Bar
Example
A navigation bar needs standard HTML as a base.
In our examples we will build the navigation bar from a standard HTML list.
A navigation bar is basically a list of links, so using the <ul> and <li> elements makes
perfect sense:
Output
<!DOCTYPE html>
<html>
<head>
<style>
ul
{
list-style-type:none;
margin:0;

<body>
<ul>
<li><a href="#">Home</a></li>
<li><a href="#">News</a></li>
<li><a href="#">Contact</a></li>
<li><a href="#">About</a></li>

CSS Image Opacity/Transparency
142
• IE9, Firefox, Chrome, Opera, and Safari use the property opacity for
transparency. The opacity property can take a value from 0.0 - 1.0. A
lower value makes the element more transparent.
• IE8 and earlier use filter:alpha(opacity=x). The x can take a value
from 0 - 100. A lower value makes the element more transparent.
• Example – I Transparent Image with Hover Effect

CSS Image Sprites
147
• An image sprite is a collection of images put into a single image.
• A web page with many images can take a long time to load and generates
multiple server requests.
• Using image sprites will reduce the number of server requests and save
bandwidth.
• Instead of using three separate images, we use this single image
(“nav_sprites.gif"):

CSS Attribute Selectors
151
• It is possible to style HTML elements that have specific attributes, not just class and id.
• The [attribute] selector is used to select elements with the specified attribute.
• The following example selects all <a> elements with a target attribute:
<!DOCTYPE html>
<html>
<head>
<style>
a[target]
{
}
</style>
</head>
<body>
<p> The links with an attribute gets an yellow background </p>
<a href="http://www.lcct.ac.th">LCCT</a>
<a href="http://www.lit.ac.th" target="_blank">LIT College</a>
<a href="http://www.google.com" target="_top">Search</a>
</body>
</html>
Output

152
• The following example selects all <a> elements with a target attribute: _blank
<!DOCTYPE html>
<html>
<head>
<style>
a[target="_blank"]
{
}
</style>
</head>
<body>
<p> The links with an attribute gets an yellow background </p>
<a href="http://www.lcct.ac.th">LCCT</a>
<a href="http://www.lit.ac.th" target="_blank">LIT College</a>
<a href="http://www.google.com" target="_top">Search</a>
</body>
</html>
Output

153
• The following example gives yellow borders with image title “flower”
Output
<!DOCTYPE html>
<html>
<head>
<style>
[title~="flower"]
{
border: 5px solid yellow;
}
</style>
</head>
<body>
<p> All images with a flower title gets yellow border </p>
<img src="image_gallery_1/klematis.jpg" title="klematis flower" width="150" height="113">
<img src="image_gallery_1/img_flwr.gif" title="flower" width="224" height="162">
<img src="image_gallery_1/img_tree.gif" title="tree" width="200" height="358">
</body>
</html>

154
• The [attribute|=value] selector is used to select elements with the specified attribute
starting with the specified value.
• The following example selects all elements with a class attribute value that begins with
"top":
• Note: The value has to be a whole word, either alone, like class="top", or followed by a
hyphen( - ), like class="top-text"!
<html>
<head>
<style>
[class|="top"]
{
background:yellow;
}
</style>
</head>
<body>
<h1 class="top-header"> Welcome to LCCT</h1>
<p class="top-text"> International Education Institute </p>
<p class="topcontent">Lampang, Thailand</p>
</body>
</html>

155
• The [attribute^=value] selector is used to select elements whose attribute value begins
with a specified value.
• The following example selects all elements with a class attribute value that begins with
"top":
• Note: The value does not have to be a whole word!
Output
<!DOCTYPE html>
<html>
<head>
<style>
[class^="top“]
{
background:yellow;
}
</style>
</head>

CSS3 Borders
156
• With CSS3, you can create rounded borders, add shadow to boxes, and use an
image as a border - without using a design program, like Photoshop.
• In this chapter you will learn about the following border properties:
– border-radius
– box-shadow
– border-image

</body>
</html>

CSS3 – Background Size Property
161
• The background-size property specifies the size of the background image.
• Before CSS3, the background image size was determined by the actual size of the image.
In CSS3 it is possible to specify the size of the background image, which allows us to re-
use background images in different contexts.
OutputExample: 1

CSS3 – Background Origin Property
165
• The background-origin property specifies the positioning area of the
background images.
• The background image can be placed within the content-box, padding-box, or
border-box area.

166
• Example : Position the background image within the content-box and border box:

167
• Code : Position the background image within the content-box and border box:
<!DOCTYPE html>
<html>
<head>

background-position:left;
}
#div1
{
background-origin:border-box;
}
#div2
{
background-origin:content-box;
}
</style>

168
• Code : Position the background image within the content-box and border box:
</head>
<body>
<p> Background-Origin Border Box</p>
<div id="div1"> LCCT has been a greatly successful institution over the time of 42 years.

}
</style>
</head>
<body>
<h1> Text Shadow Effect </h1>
</body>
</html>
• Example : Code
Output

CSS3 – Word Wrapping
172
• If a word is too long to fit within an area, it expands outside.
• In CSS3, the word-wrap property allows to force the text to wrap - even if it means
splitting it in the middle of a word.
• Example : Code
<html>
<head>
<style>
p
{
width:11em;
border:1px solid #000000;
word-wrap:break-word;
}
</style>
</head>
<body>
<p>
This paragraph contains a very
long word: thisisaveryveryveryveryveryverylongword.
The long word will break and wrap to the next line.
</p>
</body>
</html>

CSS3 – Multiple Columns
173
• With CSS3, we can create multiple columns for laying out text - like in
newspapers!
• Multiple column has the following properties:
– column-count
– column-gap
– column-rule
Output

174
• Example : Code – Part I
<!DOCTYPE html>
<html>
<head>
<style>
.newspaper
{
-webkit-column-count:3; /* Chrome, Safari, Opera */
-moz-column-count:3; /* Firefox */
column-count:3;
-webkit-column-gap:40px; /* Chrome, Safari, Opera */
-moz-column-gap:40px; /* Firefox */
column-gap:40px;
-webkit-column-rule:4px outset #ff00ff; /* Chrome, Safari, Opera */
-moz-column-rule:4px outset #ff00ff; /* Firefox */
column-rule:4px outset #ff00ff;
}
</style>

175
• Example : Code – Part II
</head>
<body>
<h1>Pride in Excellence</h1>
<div class="newspaper">
