Start your project with a remedy for the technical debt of CSS. A gift to you from Mozilla Developer Outreach.
This project is just getting started. It's too early to distribute it as part of other frameworks. Feel free to read the files and take inspiration, but do know we have a ways to go before it's really "ready to use".
We'd love to have you contribute to this project. Create or comment on an issue.
What Is This?
For years, base or reset stylesheets have helped web developers get started faster.
Early resets eliminated all visual styling, putting the burden of defining styles for every element on the webmaster. This made sense when there weren't as many elements or properties, and when each browser did something very different than the others. By zeroing everything out, you start from a blank page. There were many reset stylesheets that took this approach. Eric Meyer's became the most popular.
More recently, Normalize and similar projects took a different approach. Rather than removing all styling, they set out to create sensible defaults and eliminate browser bugs. Use one of these and you get a consistent base across all browsers.
CSS Remedy takes a slightly different approach. These days, browsers are far more consistent in how they render CSS. But there are limitations on how far browsers can improve their User Agent Stylesheet. The defaults for the web have to be consistent with the past. Many desirable changes would break millions of existing websites.
You, however, don't have to stay in the past. You can override the UA styles with more modern ideas of how CSS should work by default. Introducing CSS Remedy.
“‘Because that’s what Mosaic did’ is exactly the kind of reasoning CSS Remedy is trying to leave behind.” — Eric Meyer
- Sets CSS properties or values to what they would be if the CSSWG were creating the CSS today, from scratch, and didn't have to worry about backwards compatibility.
- Applies basic styling to form elements and controls, getting you started with custom styling. We want to find the balance between providing a base for implementing a custom design, and allowing OS-level control over how form inputs work (like how a number pad works on iOS).
- Provides a very lightweight starter file, with generic visual styling that you will want to replace. This isn't as robust or opinionated as a starter-theme or framework. We've leaned toward specifying less, so you have less to override. (We haven't defined any font families, for example.)
