The last benefit of CSS that I’m going to talk about is the fact that with CSS you can select the size of your text exactly instead of specifying a relative size.

In HTML, the font size tags are limited to being sized on a scale. Let’s use a sample scale of 1-5. 1 is a very tiny font, that’s pretty much illegible. 5 is very huge – with letters 1” tall! Most paragraph text will wind up in the 2 or 3 category, but the font size 2 is a little too small, and 3 is a little too big. There’s no “just right”.

In CSS, you can specify the font size in terms of point size – just like in Microsoft Word or any other computer application. So, you can determine if you’re more comfortable with paragraph text at 11 point, 12 point, or 13 point on your website, based on your design and what’s most legible for your target audience. It’s a much better solution, and will make your web page look a lot better.
