HTML Block and Inline

Block-level Elements

​

A block-level element always starts on a new line and takes up the full width available (stretches out to the left and right as far as it can).

​

EXAMPLE:

<div>Hello World</div>

​

​

Inline Elements

​

An inline element does not start on a new line and it only takes up as much width as necessary.

​

EXAMPLE:

<span>Hello World</span>

​

​

The <div> Element

​

The <div> element is often used as a container for other HTML elements.

The <div> element has no required attributes, but style, class and id are common.

When used together with CSS, the <div> element can be used to style blocks of content:

EXAMPLE:

<div style="background-color:black;color:white;padding:20px;">
  <h2>London</h2>
  <p>London is the capital city of England. It is the most populous city in the United Kingdom, with a metropolitan area of over 13 million inhabitants.</p>
</div>

​

​

The <span> Element

​

The <span> element is an inline container used to mark up a part of a text, or a part of a document.

The <span> element has no required attributes, but style, class and id are common.

When used together with CSS, the <span> element can be used to style parts of the text:

​

EXAMPLE:

​

<p>My mother has <span style="color:blue;font-weight:bold">blue</span> eyes and my father has <span style="color:darkolivegreen;font-weight:bold">dark green</span> eyes.</p>
