newbie question

What is a span?

Whhat is a Class selector and what is an ID selector?

Why use class if I can only use one? Why not only use ID selectors

Some reading for you:

What is a span?
http://www.w3.org/TR/1998/REC-html40-19980424/struct/global.html#edef-SPAN

Unless you mean colspan or rowspan... which means that 2 rows or columns
have been combined - which can cause fragility in a layout if the user is
not aware of the pitfalls in using these.

You have them the wrong way round. Class = an many times as you like. IDs
only once
