The Difference Between <div> and <span>
Both <div> and <span> elements are types of containers,
but with some different qualities. By default, a <div> element has infinite width (at least
to the browser edge), which can be seen by applying a border to one, like
this:
<div style="border:1px solid green;">Hello</div>
A <span> element, however,
is only as wide as the text it contains. Therefore, the following line of
HTML creates a border only around the word “Hello,” which does not extend
to the righthand edge of the browser:
<span style="border:1px solid green;">Hello</span>
Also, <span> elements
follow text or other objects as they wrap around, and can therefore have a
complicated border. For example, in Example 18-2, CSS has been used to make the
background of all <div> elements
yellow, to make all <span>
elements cyan, and to add a border to both, before then creating a few
example <span> and <div> sections.
