The act of using CSS to create a better web experience for everyone. CSSing contains examples of effective CSS techniques and smart application of tricks and tips.
Just for reference, this page has a nice multi-level version of the suckerfish dropdown: Suckerfish Dropdowns - Perciformes!
I stumbled across this site while sitting in #css on EfNet. The page is a good overview of everything related to Developing With Web Standards.
This document explains how and why using web standards will let you build websites in a way that saves time and money for the developer and provides a better experience for the visit
I've frankly never encountered that many problems using the ems unit. I have people tell me that things were "too small," but that's usually because the user had their font settings set to "small" or "smaller". Silly people.
Regardless, this is one of the best explanations of how relative font-sizing works: How to size text using ems.
If the world were an ideal place, we’d all use pixels. But it’s not, we have the broken browser to contend with. IE/Win will not allow readers to resize text that has been sized in pixels. Like it or not, your readers will want to resize text at some point. Perhaps they are short-sighted, doing a presentation, using a ridiculously high resolution laptop or simply have tired eyes. So unless you know (not think) your audience won’t be using IE/Win or will never wish to resize their text then pixels are not yet a viable solution.
The page goes on to explain how to "start" with a particular fixed unit size (ie. px) by using percentages of the default value.
As a note, I'm not sure that I would ever make the body of a non-personal site start at 62.5% of the user's default.
I'm a huge fan of Suckerfish dropdowns. In general, they're very lightweight and easy to implement. So, of course, it didn't take long for there to be the "son of suckerfish".
The original Suckerfish Dropdowns article published in A List Apart proved to be a popular way of implementing lightweight, accessible CSS-based dropdown menus that accommodated Internet Explorer by mimicking the :hover pseudo-class.
Well now they're back and they're more accessible, even lighter in weight (just 12 lines of JavaScript), have greater compatibility (they now work in Opera and Safari without a hack in sight) and can have multiple-levels.
