Em vs Px and cross browser compatibility

Question

I\'m a CSS newbie and was wondering if there is a benefit using em instead of px when it comes the cross browser compatibility of my CSS.

Answer 1

EM can be resized in some older browsers (IE 6 included) while PX do not. But frankly people that have accessibility needs to be able to resize font size are using more modern browsers.

For a CSS newbie stick with PX. EM can be a pain as they are fluid and you can have some weird effects and not sure why.

Hope this helps.
