    Why use em?

    On w3schools.com it's suggested use em instead of px because first it's relative and second it's static. I'm still confused; which is the improvement?
  2. In the help topic for text-indent http://www.w3schools.com/cssref/pr_text_text-indent.asp I think you should add a note that text-indent is commonly used with "em" since that creates indentations that are relative to the chosen font size instead of being a fixed number of pixels. The "Play It" button for the "length" option should have a radio button for "1 em" and "2 em". http://www.w3schools.com/cssref/playit.asp?filename=playcss_text-indent I didn't know anything about "em" and had never seen it until someone else saw the difficulties I was having with trying to set fixed pixel sizes. Having that more on this tutorial page would have helped me.

  11. From some of my webpages (in php) I've created html-files for the printer, so leaving the navigation column and some other elements out.It works fine so far, but I want the user give the opportunity to scale the font size from within the document (because dummies can surely not find the browser's menu option). For that reason my font sizes are given in em instead of px, in order to accomodate IE8 and lower. Often you see a number of different sized A-characters in a document as links to larger/smaller font sizes. Unfort. I cannot figure out what's behind those links. Is it CSS or javascript perhaps? Thanks and regards,Egbert Zijlema
