Font-size not a value?

are percentages wrong?

In my .css I have set my main body text font size to 100% and all other font sizes in proportion to it, like 87% or 120%. The W3C css validator doesn't like any of those percentages, tells me it's an error, and says they're not font-size values. How critical is this? Should I set my main body text to, say, 12pt or 12px, and leave the other percentages, or are percent values totally wrong?

Have you tried 'em'?

Like font-size: .8em;
or , font-size: .9em;

Hope this helps.

Percentages are perfectly valid for font-size: [w3.org...]

Perhaps your syntax is off? It might help if you posted a snippet.

FWIW, 1.0em=100% so you can substitute ems for percents in most cases without serious issues.

You could try using a descriptive size for the body text setting i.e. small, x-small etc. then make the other font sizes variants of that setting in EMS.

Did you fix it?

There must have been some other typo that affected it?
