Hey,
I just noticed that the links above the description on a YouTube video page change their colors with opacity and not hex codes or something else. So, a normal link which is not active has an opacity of like 0.8 or so, and the highlighted links have their own colors without opacity.
I was just wondering if that is recommendable. Okay, all browsers [support it](http://caniuse.com/css-opacity “Opacity”), but wouldn’t it just be easier to use hex colors? Or does it not matter at all?
Thanks for your opinion.
