Here is how to define the font size using CSS.

(i) — Simply use the property font-size in your CSS style sheet.

Example:
.mytext{ font-size: 12 px; }

You can define the font size in px, em, percentage, or "big", "small" etc.
Use px for an exact pixel font size, or simply a percentage based on the main font size, so all your font-sizes are linked to the main font-size, useful when changing the base font size, you don't have to change all other font-sizes!

Example:
html{ font-size: 18px; } h1{ font-size: 200%; } h2{ font-size: 150%; }

Simply use the property font-size in your CSS style sheet.

Example:
.mytext{ font-size: 12 px; }

You can define the font size in px, em, percentage, or "big", "small" etc.
Use px for an exact pixel font size, or simply a percentage based on the main font size, so all your font-sizes are linked to the main font-size, useful when changing the base font size, you don't have to change all other font-sizes!
