HTML Elements: Some of the Elements Used in HTML – Chapter 4

HTML Elements

The HTML elements mainly comprises of a start tag and end tag, with the content inserted in between:
<tagname>Content goes here…</tagname>
The HTML element is everything from the begin tag to the end tag:
<p>My first paragraph.</p>

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

 

HTML elements with no content are called empty elements. Empty elements does not contain an end tag, such as the <br> element (which is used for a line break).

Nested HTML Element

HTML elements can be nested (elements can contain elements).
All HTML documents consist of nested HTML elements.
This example contains four HTML elements:

Example

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

Example Explained

The <html> element defines the whole document.
It has a start tag <html> and an end tag </html>.
The element content is another HTML element (the <body> element).

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

The <body> element defines the document body.
It has a start tag <body> and an end tag </body>.
The element content is two other HTML elements (<h1> and <p>).

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

The <h1> element defines a heading.
It has a start tag <h1> and an end tag </h1>.
The element content is: My First Heading.

<h1>My First Heading</h1>

The <p> element defines a paragraph.
It has a start tag <p> and an end tag </p>.
The element content is: My first paragraph.

<p>My first paragraph.</p>

Do Not Forget the End Tag

Some elements of HTML 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>

The example above can work in all browsers, as the closing tag is considered optional for these tags.

Never rely on this because it might produce unexpected results and/or errors if you forget to put the end tag.

Empty HTML Elements

Those HTML elements which do not have any content are called empty elements.
<br> is an empty element without a closing tag (the <br> tag defines a line break).
Empty elements can be “closed” in the opening tag like this: <br />.
In HTML5 there is no need to close empty elements. But if you want stricter validation, or if you want to make your document readable by XML parsers, you must close all HTML elements properly.

Use Lowercase Tags

HTML tags are not case sensitive: for example <P> means the same as <p>.
It is not necessary to use lowercase tags according to HTML5 standard. But we (geektutes.com) suggests you to use lowercase for all tags in HTML5, and demands lowercase for stricter document types like XHTML.

At geektutes.com we always use lowercase tags.
