HTML Beginner tutorial 3 HTML Elements

HTML Elements
An HTML element is everything from the start tag to the end tag. 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

Nested HTML Elements
Most HTML elements can be nested (can contain other HTML elements).
HTML documents consist of nested HTML elements.

For example:-
html elements
html elements.

The example above contains 3 HTML elements.


The <p> element
<p>The sun rises in the East.</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: The sun rises in the East.

The <body> element
<body>
<p>The sun rises in the East.</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>The sun rises in the East.</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>The sun rises in the East
<p>The sun rises in the East

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).

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 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.
