(HTML Elements (Part 4


An HTML element is defined by a start tag, some content, and an end tag ( Elements)


Elements

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

<tagname>   Content goes here...   </tagname>

Examples of some elements

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

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 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>)

<!DOCTYPE html>
<html>
<body>

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

</body>
</html>

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

<body>

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

</body>

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>

<p>    My first paragraph   </p>

Never Skip the End Tag

Some elements are displayed correctly, even if you forgot the end tag

<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!


Blank HTML elements

Content-free elements are called empty elements.
The <br> tag defines a line break, and is an empty element without a closing tag

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

HTML is Not Case Sensitive

HTML tags are not case sensitive : <P> means the same as <p> .
The HTML standard does not require small tags, but vnstagram recommends lowercase for HTML
