Can I Use…?

As part of my daily job as a web developer, I am constantly plagued with the different implementations of CSS layout definitions in different web browsers. The most useful website I’ve found to use over the past year is “Can I Use” by Alexis Deveria, which contains a maintained and comprehensive list of which technology is supported in which browsers.

For example, finding out whether you can use CSS gradients in all browsers is easy: the search term caniuse linear-gradient takes you straight to the CSS gradients page, which tells us that the technology is supported according to the W3C standards in all current browsers except Opera Mini.
