HTML Elements
The HTML element is everything from the start tag to the end tag:
Examples of some HTML elements:
Nested HTML Elements
HTML elements can be nested (this means that elements can contain other elements).
All HTML documents consist of nested HTML elements.
The following example contains four HTML elements (<html>, <body>, <h1> and <p>):
<html>
<body>
<h1>My First Heading</h1>
<p>My first paragraph.</p>
</body>
</html>
The <body> element defines the document's body.
It has a start tag <body> and an end tag </body>.
Then, 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>
Never Skip the End Tag
Some HTML elements will display correctly, even 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
<!DOCTYPE html>
<html>
<body>
<p>This is a <br> paragraph with a line break.</p>
</body>
</html>
