HTML Elements
An HTML element is defined by a start tag, some content, and an end tag.
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 Parragraph</p>
| Start tag | Element content | End tag |
|---|---|---|
| <h1> | My First Heading | </h1> |
| <p> | My first paragraph. | </p> |
| <br> | none | none |
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 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 Document
Example Explained
The <html> element is the root element and it defines the whole HTML document.
It has a start tag <html> and an end tag </html>.
Then, inside 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, inside 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 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:
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:
HTML is Not Case Sensitive
HTML tags are not case sensitive: <P> means the same as <p>.
The HTML standard does not require lowercase tags, but W3Crecommends lowercase in HTML, and demands lowercase for stricter document types like XHTML.
