The difference between
div is that a
span element is in-line and usually used for a small chunk of HTML inside a line (such as inside a paragraph) whereas a
div (division) element is block-line (which is basically equivalent to having a line-break before and after it) and used to group larger chunks of code.
<div id="scissors"> <p>This is <span class="paper">crazy</span></p> </div>
div and especially
span shouldn’t actually be used that often. Whenever there is a sensible alternative that should be used instead. For example, if you want to emphasize the word “crazy” and the class “paper” is adding italics for visual emphasis, then, for richer, more meaningful content, the code might look like this:
<div id="scissors"> <p>This is <em class="paper">crazy</em></p> </div>
If you haven’t got a clue about classes and ID’s yet, don’t worry, they’re all explained in the CSS Intermediate Tutorial. All you need to remember is that span and div are “meaningless” tags.
