Html Elements

  • An HTML element is declared by a start tag, some content, and an end tag.

  • The HTML element is everything from the start tag to the end tag:<tagname>Content goes here…</tagname>

Example:

				
					<!DOCTYPE html>
<html>
<body>
<h1>My First Heading</h1>
<p>My first paragraph.</p>
<h1>My First Heading</h1>
<p>My first p</p>
</body>
</html>

				
			

Output:

My First Heading

My first paragraph.

My First Heading

My first p

Nested HTML Elements

HTML elements can be nested which means that the elements can contain other elements. All HTML documents have nested HTML elements.

The following example contains four HTML elements (<html>, <body>, <h1> and <p>)

Example

				
					<!DOCTYPE html>
<html>
<body>
<h1>My First Heading</h1>
<p>My first paragraph.</p>
</body>
</html>

				
			

Output:

My First Heading

My first paragraph.

Example Explained:

  • The <html> element is the root element that defines the whole HTML document.
  • It consists of a start tag <html> and an end tag </html>.
  • Within the <html> element there is a <body> element.
  • The <body> element defines the document’s body.
  • It has a start tag <body> and an end tag </body>.
  • Then, within the <body> element there are two other elements: <h1> and <p>

The <h1> element defines a heading.

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

The <p> element describes a paragraph.

It consist of a start tag <p> and an end tag </p>

Never skip The End Tag

Some of the  HTML elements are displayed correctly, even if you forget the end tag:

Example

				
					<!DOCTYPE html>
<html>
<body>
<p>This is a paragraph.</p>
<p>This is a paragraph.</p>
</body>
</html>

				
			

Empty HTML Elements

HTML elements consist of no content and are called empty elements.

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

Example

				
					<!DOCTYPE html>
<html>
<body> 
<p>This is a <br> paragraph with a line break.</p>
</body>
</html>

				
			

Output:

This is a
paragraph with a line break.
