Can we get rid of gradient prefixes?

I recently realized that unprefixed gradients finally propagated to stable Chrome, and after tweeting about it, I decided to do some research on which browsers support unprefixed gradients, and what percentage of users needs them.

Currently, unprefixed gradients are supported in:

  • Chrome 26+
  • Firefox 16+
  • Opera 12.10+
  • IE10+

Lets have a look at which prefixes we actually need to use for gradients today.

-ms-

There was never a stable release of IE that supported -ms- prefixed gradients, those were only in preview versions (stable IE10 supports both prefixed and unprefixed gradients). So, -ms- is most definitely not required.

-moz-

Firefox versions >= 3.6 and < 16 account for 4% of the global user base*. This might or might not be significant, depending on how good the fallback is that these users will see. If the gradient only adds a subtle shadow or something like that, I’d say ditch -moz-. If it’s more crucial to the design & branding, it might be wise to still keep it. More tech-focused websites probably have a much lower percentage than 4%, so it might be a good idea to drop it there completely.

-o-

Opera unprefixed gradients in 12.10. Opera Mini never supported them. Opera versions < 12.10 currently account to a total of 0.25% of the global user base*. I’d say it’s safe to ditch -o- in gradients in most cases.

-webkit-

Chrome only very recently unprefixed gradients and Safari is a long way from doing so. Not to mention all the mobile browsers using WebKit. Unfortunately, we can’t ditch -webkit- in CSS gradients just yet.

My opinion

Don’t use -ms- prefixed gradients, there’s absolutely zero point in doing so. Include -moz- for the less subtle gradients. No significant need for -o- gradients. -webkit- is still needed and probably will be at least until the end of 2013. Or, of course, just use -prefix-free and don’t bother. 😛

Keep in mind that your stats might differ from global stats, so which prefixes you need to include might differ on a case by case basis. The purpose of this post is to alert you that maybe you don’t need all these prefixes, not to prescriptively tell you which ones to keep. Except -ms-, please don’t use that. There’s absolutely zero reason whatsoever.

Last but not least, no matter which prefixes you include, always have a good solid color fallback!
