HTML Elements
An HTML element is everything from the
start tag
to the
end tag:
| Start tag /opening tag |
Element content |
End tag /closing tag |
| <p> |
This is a paragraph |
</p> |
| <a href="default.htm" > |
This is a link |
</a> |
| <br /> |
|
|
Not: Empty elements are closed in the start tag
<br />
Nested HTML Elements
Most HTML elements can be nested (can contain other HTML elements).
<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> and
</p> element
).
Don't Forget the End Tag
Some HTML elements might display correctly even if you forget the end tag:
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 .
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.
