Some thoughts about CSS from Nicole Sullivan:
[T]he things we considered best practices were leading to the bad outcomes we sought to avoid. I realized (unpopular though it might be), that we couldn’t make it work out well by trying harder. Each time we start a new project, we think “this time, I’m going to keep the code clean. This time the project will be a shining example of what can be done with CSS.” And without fail, over time, as more content and features are added to the site, the code becomes a spaghetti tangle of duplication and unpredictability.
It is time to let ourselves off the hook. There is nothing we could have done by trying harder. There is no magic juju that some other developer has that we don’t. Following our beloved best practices leads to bad outcomes every. single. time.
What are those flawed best practices?
- Never add an non-semantic element
- Or, a non-semantic class
- Use descendant selectors exclusively
- Sites need to look exactly the same in every browser
