HTML Basic Examples
Don't worry if the examples use tags you have not learned.
You will learn about them in the next chapters.
HTML Headings
HTML headings are defined with the <h1> to <h6> tags.
Example
<h1>This is a heading</h1>
<h2>This is a heading</h2>
<h3>This is a heading</h3>
HTML Paragraphs
HTML paragraphs are defined with the <p> tag.
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
HTML Links
HTML links are defined with the <a> tag.
Example
<a href="http://www.w3schools.com">This is a
link</a>
Note: The link address is specified in the href attribute.
(You will learn about attributes in a later chapter of this tutorial).
HTML Images
HTML images are defined with the <img> tag.
Example
<img src="w3schools.jpg"
alt="W3Schools.com" width="104" height="142">
Note: The filename and the size of the image are provided as
attributes.

HTML Elements
HTML documents are defined by HTML elements.
HTML Elements
An HTML element is everything from the start tag to the end tag:
Start tag *
|
Element content
|
End tag *
|
<p>
|
This is a paragraph
|
</p>
|
<a href="default.htm">
|
This is a link
|
</a>
|
<br>
|
|
|
* The start tag is often called the
opening tag. The end tag
is often called the
closing tag.
HTML Element Syntax
- An HTML element starts with a
start tag / opening tag
- An HTML element ends with an end
tag / closing tag
- The element content is
everything between the start and the end tag
- Some HTML elements have empty
content
- Empty elements are closed
in the start tag
- Most HTML elements can have attributes
Tip: You will learn about attributes in the next chapter of this
tutorial.
Nested HTML Elements
Most HTML elements can be nested (can contain other HTML elements).
HTML documents consist of nested HTML elements.
HTML Document Example
<!DOCTYPE html>
<html>
<body>
<p>This is my first paragraph.</p>
</body>
</html>
The example above contains 3 HTML elements.
HTML Example Explained
The <p> element:
<p>This is my first paragraph.</p>
The <p> element defines a paragraph in the HTML document.
The element has a start tag <p> and an end tag </p>.
The element content is: This is my first paragraph.
The <body> element:
<body>
<p>This is my first paragraph.</p>
</body>
The <body> element defines the body of the HTML document.
The element has a start tag <body> and an end tag </body>.
The element content is another HTML element (a p element).
The <html> element:
<html>
<body>
<p>This is my first paragraph.</p>
</body>
</html>
The <html> element defines the whole HTML document.
The element has a start tag <html> and an end tag </html>.
The element content is another HTML element (the body element).
Don't Forget the End Tag
Some HTML elements might display correctly even if you forget the end tag:
<p>This is a paragraph
<p>This is a paragraph
The example above works in most browsers, because the closing tag is
considered optional.
Never rely on this. Many HTML elements will produce unexpected results
and/or errors if you forget the end tag .
Empty HTML Elements
HTML elements with no content are called empty elements.
<br> is an empty element without a closing tag (the <br> tag
defines a line break).
Tip: In XHTML, all elements must be closed. Adding a slash inside the
start tag, like <br />, is the proper way of closing empty elements in
XHTML (and XML).
HTML Tip: Use Lowercase Tags
HTML tags are not case sensitive: <P> means the same as <p>.
Many web sites use uppercase HTML tags.
W3Schools use lowercase tags because the World Wide Web Consortium (W3C)
recommends
lowercase in HTML 4, and
demands lowercase tags in XHTML.
