Vendor Prefixes

Write your CSS without vendor prefixes. Keep it simple.

The modern way

Use a post-processor like Autoprefixer to support vendor prefixes intelligently so your build process does the heavy lifting.

You define the browsers you need to support, and it uses data from Can I Use to insert only the prefixed properties you need.

Deprecated

Don’t use these methods anymore.

Mixin libraries

From 2011–2015 I used Sass with the Compass mixin library.

The stupid way

Write vendor prefixes by hand.
