Main Concepts and Principles Explained
● HTML stands for hypertext markup language.
● Content structure => make your websites easy-to-read and improve user
experience by dividing texts into paragraphs, lists, quotes, and headings.
● When comparing HTML vs HTML5, the first major difference is the level of support.
Websites created with HTML5 can be used across all major browsers and different
platforms as well.

<head>
<title>Name of the website</title>
</head>
<body>
<div>
<h1>Heading for the content below</h1>
<p>Text text text</p>
</div>
</body>
</html>
● The <!DOCTYPE> Declaration : informs the browser about
the document type , not case sensitive .
● The <html> element: used to define an HTML document .
● The <head> element: contains all information about what is

Head Element
● define meta data (such as the title of the page or related keywords). It is also where
you'd place JS scripts or CSS stylesheets.
● The content of head section not shown to the users of the website: instead, it gives
instructions for the machine to display a webpage correctly.
○ <title>Document title</title>
defines the HTML page title
○ <link rel="stylesheet" type="text/css" href="style_file.css">
creates a relation to external resources (stylesheets or scripts)
○ <script>
document.getElementById("learn").innerHTML = "It works!";
</script>
include a JS script in your HTML document
○ <head>
<meta charset="UTF-8">
<meta name="description" content="Learn to code!">
<meta name="keywords" content="HTML, PHP,
JavaScript">
<meta name="author" content="The BitDegree Team">
</head>
define meta information about the document

What is an Empty Element in HTML?
elements are mostly used to add or embed content into documents ,do not need a closing tag
because there simply is no content for them to wrap around.
<img src="image.png" alt="Doggo" width="205" >
<area> <base> <br> <col> <embed>
<hr> <img> <input> <keygen> <link>
<meta> <param> <source> <track> <wbr>
Optional closing tags :
<p>Paragraph element without end tag
<html> <head> <body> <p> <dt>
<dd> <li> <option> <thead> <th>
<tbody> <tr> <td>
<tfoot> <colgroup>

HTML Character Encoding
character encoding huge selection of characters available. Apart from your usual Latin letters and
Arabic numbers, there are also foreign alphabets, mathematical symbols and other special
characters.
The first and simplest HTML character encoding is called ASCII stands for the American Standard
Code for Information Interchange
128 characters
Lowercase letters - Uppercase letters - Punctuation symbols - Numbers from 0 to 9
33 unprintable characters are also called control characters.
Your Best Option: UTF-8
Unicode is the industry standard used for the consistency of character encoding. such as UTF-
8, UTF-16, and UTF-32.
UTF-8 stands for Unicode Transformation Format 8-bit
reasons to use UTF-8:
It supports many languages - completely compatible with ASCII - natively used by XML - uses
less space than other Unicode encodings.
<meta charset="UTF-8">

HTML Text Formatting
<em> tag is used for emphasizing. Most browsers italicize HTML text within these tags –
however, this element conveys not only visual but also semantic meaning
<em>This text is emphasized.</em>
italicize HTML text without any semantic meaning, use the <i> tag:
<i>This text is in italics.<i>
<strong> tag defines important text. Browsers display it as bold text
<p>This is <strong>important</strong> text.</p>
bold text without any semantic meaning
<p>Normal text vs <b>Text in bold</b></p>
<u> tags, you can underline text
Here is some <u>underlined</u> text
<small> tags can be used to make the text smaller without changing the height of the line
<p>Paragraph with <small>smaller text</small> in it.</p>
opposite tag called <big> has been removed from HTML5
<center> element used to center text in HTML
<center>Everything here will be displayed in the center of the document.</center>

HTML Text Formatting
<mark> tags highlight HTML text in bright yellow color to resemble using a highlighter pen
<p>The mark tag is <mark>useful</mark> when you need to highlight important
information.</p>
<del> tags cross out your text is still visible in the final copy so don't use this tag if you want to
actually delete it!text to mark it as deleted
<p>I am not deleted text, but <del>I am.</del></p>
<s> tags create a similar visual effect as <del> but have a different semantic meaning – they
define a text that is no longer relevant
<p><s>This text is not relevant.</s></p>
<ins> tags mark inserted HTML text
<ins>This text is inserted</ins>
<sub> tags create subscript text which is half the size of the usual text and also has a lower line
<p>This text contains <sub>subscript</sub> text.</p>
<sup> tag defines an HTML superscript text
<p>The following is <sup>superscript</sup>.</p>

HTML Quoting and Citing
<dfn> tag is used to define the term, that is mentioned for the first time. The content of the tag is
displayed in italic.
<p><dfn>HTML</dfn> (HyperText Markup Language ) — The standardized markup language for
documents on the World Wide Web.</p>
blockquote and q are used for quotations. blockquote is generally used for standalone often
multi-line quotations whereas q is used for shorter, in-line quotations.
<p>So I asked Bob about quotations on the Web and he said <q>I know as much about quotations
as I do about pigeon fancying</q>. Luckily, I found HTML Dog and it said:</p>
<blockquote cite="http://www.htmldog.com/guides/html/intermediate/text/">
<p>blockquote and q are used for quotations. blockquote is generally used for standalone often
multi-line quotations whereas</p>
<cite> element defines the title of the work you're citing or quoting.

Computer Code
HTML computer code is displayed with fixed letter size, font, and spacing.
<code> tags define an HTML code snippet on your website text will be displayed in a
default monospace font:
<code>
a = 6;
b = 9;
c = "this is the best program";
</code>
<samp> element depicts the output of the system or computer in your HTML
document. The font, size, and spacing remain the same as with other HTML code
elements:
This is an output of a program ->
<samp>
a + b + c = alotOfNumbers
</samp>
<kbd> element also defines a fragment of HTML code, according to HTML syntax, it
should only be used to display a keyboard input:
Press <kbd>Ctrl + O</kbd> to open a document file
<var> element defines a variable. It can be used to define variables in mathematics or
programming:
<p>Einstein's best known equation goes like this:
<var>E</var> = <var>mc</var><sup>2</sup></p>

YouTube Video
Understanding how to embed a YouTube video in HTML can save you a lot of trouble.
The trick is using an iframe instead of the <video> tags
As you click it, you will see a few sharing options, including various social media
platforms. The very first on the list is Embed. Click on it with your cursor:
YouTube will generate a code for you to use automatically. The <iframe> tag will have
the URL of the video source, height and weight of the player and a few more attributes
included
<iframe width="560" height="315"
src="https://www.youtube.com/embed/RuckLtuInNY" frameborder="0"
allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture"
allowfullscreen></iframe>
