Internal Server Error

what the voices in my head tell me to write

Some times you just have to do things backwards to do them right 

I have been struggling with the font-size switcher on Ingentaconnect for ages. A year on and off.

I was assigned a bug that basically said "If you turn off javascript the font-size is smaller and some layout breaks." When I looked at the CSS in that light I suddenly realised that I had been assigning <body> a pixel font size in the default style sheet and then using ems to resize various bits in the switched in css files.

This meant that the switched in files were pretty huge as I had to account for lots of little divs etc and if I had a <li> nested within a <div> it would do the sizing twice unless I added in an inherit rule. Of course this was a very hard to maintain mess.

Now the switcher files simply change the font-size for <body> and another CSS file is defining the sizes in ems for <h1>, <h2> etc. (Of course there is a little hack for IE not getting sizes right) Its about a 95% reduction in the ammount of CSS and far easier to work with.
