If you're in need of a media query specifically for Chrome, there's now a way to target different versions. Through extensive research and testing, I was able to come up with a solution that works effectively. Several months ago, I shared this discovery on browserhacks.com where I conduct various tests. The media query I developed can successfully target Chrome 29 and above, including the latest development and Canary versions up to version 40.
Instead of using the traditional Chrome + Safari media query within your mixin, consider using this code snippet:
@media screen and (-webkit-min-device-pixel-ratio:0) and (min-resolution:.001dpcm) {
border-bottom: red;
}
I've also conducted live tests for this method along with others that I've created. You can find them all here:
