In my website CSS, I’m using EM, PX, PT and Percentages to set the font sizes.
I am also using JQuery UI which uses EM.
I have now come to the point where I need to resize all the font sizes to slightly smaller.
All in all, what’s the best what of bringing all the font sizes down a bit and should I be changing how I’m doing font sizes to whichever way?
Everyone seems to have a different opinion on this topic.
the best practice for sizing fonts is em. because it is not related to users client resolution. but I use pixels in my own applications. because I want to render smaller fonts in higher resolutions.
but percent is not recommended for font size at all.
also you can see this thread for comparison
