When to use CSS3
CSS3 Support chart
Only on the presentation layer
- Branding, usability, accessibility and layout must be supported by all browsers.
- Try to have a fallback for less capable browsers.
Know your audience
- Are they on mobile devices?
- Still using old versions of IE?
Don't go crazy
- Using too many CSS3 properties at once on a page will slow down a browser's performance.
- Check browser support for CSS3 before you start.
