22,916 PointsIs there a reason to use px instead of ems?
For the previous/next buttons in this video he uses px and then resizes with a media query. Is this just a matter of habit or is there a reason to use px? I have been slowly converting my brain to use ems for everything but have come across a few wordpress plugins that will only let me use px for font sizes. Is there a reason I should be using px? Or should I just sit back and wait for the world to adapt to ems?

If there is no need for the element to grow relative to it's parent, there is no need to take the risk using ems.
