html - When to use <span> instead <p>?

Question

As the question indicates, if I have some text that I want to add in the HTML then when should I use <p> and when should I use <span>?

Answer 1

You should keep in mind, that HTML is intended to DESCRIBE the content it contains.

So, if you wish to convey a paragraph, then do so.

Your comparison isn't exactly right, though. The more direct comparison would be

When to use a <div> instead of a <p>?

as both are block level elements.

A <span> is inline, much like an anchor (<a>), <strong>, emphasis (<em>), etc., so bear in mind that by it's default nature in both html and in natural writing, that a paragraph will cause a break before and after itself, like a <div>.

Sometimes, when styling things — inline things — a <span> is great to give you something to "hook" the css to, but it is otherwise an empty tag devoid of semantic or stylistic meaning.
