I just wished that people who are designing HTML/CSS content use relative font sizes instead of fixed pixel font sizes.
For example, Macromedia’s new Help content uses relative font sizes (such as x-small or xx-small), instead of fixed point sizes (such as 8-pt or 6-pt). Why is this good? Because if I find the font size too small, I can bump it up easily by Ctrl-scrolling my mouse wheel (you can try it on this page if you’re using Windows(?) Internet Explorer)! However, if the font sizes are fixed in points, this doesn’t work.
Many sites/blogs I visit use fixed point sizes, some text are so tiny (especially if they’re using the <code> tag), that it makes reading difficult (especially at my 1920×1200 laptop screen). Sites such as Macromedia.com or Microsoft.com use relative font size – makes sense for everyone, including those of us who are not visually-challenged (yet).
