This is the CSS Tutorial for Beginners that teach the basics of CSS. This tutorial will show the basic structure of a CSS style and will show 3 different methods to apply styles.
Cascading Style Sheets (CSS) is a style sheet language used to describe the presentation of HTML and XML documents. CSS separates document content from document presentation, enabling control over elements like layout, colors, and fonts. This separation improves accessibility, flexibility, and maintenance of web pages. CSS can format pages for different rendering methods like on-screen, in print, and for speech-based browsers.
The document discusses the three types of CSS - internal, external, and inline. Internal CSS is defined within the HTML document using <style> tags. External CSS is defined in a separate .css file and linked using <link> tags. Inline CSS is defined directly in HTML elements using the style attribute. IDs and classes are also discussed as ways to target elements with CSS selectors.
A standards-based method for controlling the look and feel of XML content.
Comprised of Rules to control elements in the document.
Designed to separate formatting from the content while being flexible and scalable
CSS specifies a priority scheme to determine which style rules apply if more than one rule matches against a particular element.
CSS (Cascading Style Sheets) allows separation of document content from page layout/presentation. CSS was introduced to make web page design and modification easier. CSS properties control elements like text formatting, page layout, and color/images. CSS rules cascade from broad to specific with author styles overriding browser defaults. Common selectors target elements by ID, class, tag name or relationship.
The document covers various topics related to CSS including CSS introduction, syntax, selectors, inclusion methods, setting backgrounds, fonts, manipulating text, and working with images. Key points include how CSS handles web page styling, the advantages of CSS, CSS versions, associating styles using embedded, inline, external and imported CSS, and properties for backgrounds, fonts, text formatting, and images.

2. What is CSS?
• Cascading: Multiple styles can overlap in order
to specify a range of style from a whole web site
down to a unique element. Which style gets
applied pertains to the rules of CSS cascading
logic.
• Style: CSS deals specifically with the
presentation domain of designing a web page
(color, font, layout, etc).
• Sheet: Normally, CSS is a file separate from the
HTML file – linked to the HTML file through its
<head> (exceptions apply).
3. Why CSS?
• Allows for much richer document appearances
than HTML.
• Reduce workload by centralizing commands for
visual appearance instead of scattered
throughout the HTML doc.
• Use same style on multiple pages.
• Reduce page download size.
Use HTML for content; CSS for Presentation.
5. CSS Syntax
Selector Style Block
h1 {
color: red; Style
Element Values
Properties background: yellow;
}
•The Selector selects elements on the HTML page.
•The associated Style Block applies its Style Values to the selected
Element’s Properties
6. Selectors
• Select elements to apply a declared style.
• Selector types:
– Element Selectors: selects all elements of a
specific type (<body>, <h1>, <p>, etc.)
– Class Selectors: selects all elements that
belong to a given class.
– ID Selectors: selects a single element that’s
been given a unique id.
– Pseudo Selectors: combines a selector with a
user activated state (:hover, :link, :visited)
7. Element Selectors
• Finds all HTML elements that have the specified
element type.
• Example:
h1 {
color: blue;
}
Finds all elements of type <h1> and makes the
text color blue.
8. Class Selectors
• Finds all elements of a given class – based on the
attribute’s class value.
• Syntax: .classname (Remember the dot means class
selector)
• Example:
.legs {
font-weight: bold;
background: pink;
}
Finds all elements whose class = “legs” and makes their
font bold and their backgrounds pink.
9. ID Selectors
• Finds a single element that’s been given a
unique id – based on the attribute’s id value.
• Syntax: #idname (Remember the pound-sign
means id selector)
• Example:
#snout{
border: solid red;
}
Finds a single element whose id = “snout” and
gives it a solid red border.
10. Pseudo-Selectors
• Apply styles to a user activated state of an
element.
• If used, must be declared in a specific order in
the style sheet.
• General Purpose Pseudo-Selector:
– :hover Element with mouse over
• Specific to hyperlinks (and/or buttons)
– a:active A link or button that is currently being
clicked on.
– a:link A link that has NOT been visited yet.
– a:visited A link that HAS been visited.
11. Grouping Selectors
• Lets say you want to apply the same style to several
different selectors. Don’t repeat the style – use a
comma!!
• Syntax: sel1, sel2, sel3 (Remember the comma to
group several different selectors)
• Example:
h1, .legs, #snout{
font-size: 20pt;
}
Finds all elements of type <h1>, all elements with
class=“legs” and the single element whose id = “snout”
then makes their font-size 20pt.
12. Conflict Resolution
• It’s possible to have different styles
applied to the same selector
(CascadingSS), but what if the styles tell
the browser to do conflicting things?
• Rules:
– Which selector is more specific?
– If the selectors are the same, then which style
was applied last?
13. Sharpen Your Selector
• Order of specificity:
(specific) id, class, element type (ambiguous)
• Combine selectors:
Elementype.classname or Elementype#idname
e.g. p.legs or h2#snout
14. Sharpen Your Selector (cont.)
• Descendant Selectors:
Specify the context in the HTML tree from each ancestor down to the
desired element – each separated by a space.
e.g. body.pig p.pig-head #snout
• HTML Tree:
<body class=“pig”>
<p class=“pig-head”>
<h1 id=“snout”>
Snout Snout Snout
</h1>
</p>
</body>
15. Firebug – Firefox Addon
• Tool for figuring out what styles are being
applied to which element (and which are being
overwritten due to conflict resolution).
• http://getfirebug.com/
• Right-click on an element,
then select “Inspect Element” from the dropdown
menu.
16. <span> Element tag
• Useful for applying style to text within
another HTML element.
• Use SPARINGLY – unlike <h1> or <p>,
<span> has no semantic meaning.
• Remember, HTML is for content and
HTML tags are for describing that content
to non-human or visually-impaired
readers. <span> is just used to make
things “pretty.”
17. <div> Element tag
• Useful for dividing parts of the page into sections.
• Creates a “box” with the following attributes:
– margin
– padding
– border
– height
– width
– (..and lots more)
• Primary element used for CSS Layouts
(more information in CSS Layouts tutorial)
