Every HTML element has a default display value depending on what type of element it is. The default display value for most elements is block or inline.
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).The <div> element is a block-level element.
Examples of block-level elements:
An inline element does not start on a new line and only takes up as much width as necessary.
Examples of inline elements:
The <div> element is often used as a container for other HTML elements.
The <div> element has no required attributes, but both style and class are common.
When used together with CSS, the <div> element can be used to style blocks of content:
<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>
The <span> element is often used as a container for some text.
The <span> element has no required attributes, but both style and class are common.
When used together with CSS, the <span> element can be used to style parts of the text:
<h1>My <span style="color:red">Important</span> Heading</h1>
