HTML Elements

HTML Elements

The HTML element is everything from the start tag to the end tag:

<tagname>Content goes here…</tagname>

Examples of some HTML elements:

<h1>My First Heading</h1>
<p>My first paragraph.</p>
Start tagElement contentEnd tag
<h1>My First Heading</h1>
<p>My first paragraph.</p>
<br>nonenone

Note: Some HTML elements have no content (like the <br> element). These elements are called empty elements. Empty elements do not have an end tag!

Nested HTML Elements

HTML components can be settled (this implies that components can contain different components).

All HTML reports comprise of settled HTML components.

The accompanying model contains four HTML components (<html>, <body>, <h1> and <p>):

Example

<!DOCTYPE html>
<html>
<body>

<h1>My First Heading</h1>
<p>My first paragraph.</p>

</body>
</html>

Example Explained

The <html> element is the root component and it characterizes the entire HTML record.

It has a beginning tag <html> and an end tag </html>.

At that point, inside the <html> element there is a <body> element:

<body>

<h1>My First Heading</h1>
<p>My first paragraph.</p>

</body>

The <body> element characterizes the archive’s body.

It has a beginning tag <body> and an end tag </body>.

At that point, inside the <body> element there are two other elements: <h1> and <p>:

<h1>My First Heading</h1>
<p>My first paragraph.</p>

The <h1> element defines a heading.

It has a start tag <h1> and an end tag </h1>:

<h1>My First Heading</h1>

The <p> element defines a paragraph.

It has a start tag <p> and an end tag </p>:

<p>My first paragraph.</p>

Never Skip the End Tag

Some HTML elements will display correctly, even if you forget the end tag:

Example

<html>
<body>

<p>This is a paragraph
<p>This is a paragraph

</body>
</html>

However, never rely on this! Unexpected results and errors may occur if you forget the end tag!

Empty HTML Elements

HTML elements with no content are called empty elements.

The <br> tag defines a line break, and is an empty element without a closing tag:

Example

<p>This is a <br> paragraph with a line break.</p>

HTML is Not Case Sensitive

HTML labels are not case sensitive: <P> means the equivalent as <p>.

The HTML standard doesn’t need lowercase labels, yet W3C recommends lowercase in HTML, and demands lowercase for stricter record types like XHTML.
