which one is faster: hex color codes or color names?
In terms of page rendering speed, does it make any diference to the browsers if the color in the css file is written as
color: #000;
opposed to
color: black;
Naturally, my guess would be it does not, but since I didn’t find any viable resources about it on the net, I’m asking for your opinion and possibly a more detail explanation than to just ‘no’.
My guess would be that the hex code is slightly faster because the browser doesn’t have to look up and translate the word.
You can check this unofficial test http://www.webmasterworld.com/css/4151070.htm?highlight=msg4158590, which supports the idea that it doesn’t really make a noticeable difference :]
