Lowercase

I have been caught doing both … would not spend too much time thinking about it either way until someone tells it actually matters … css4 maybe? ;)

I type all of the selectors and others in lowercase so I stick with the same thing when it comes to the hex colors.

I used to exclusively do upper case, and now have officially switched to lower. Probably made sense at the time to not have to hit Shift or Caps-Lock! -cb I’m with you.

I first read this post yesterday. While I was reading the comments I began to wonder which one is most correct. My first thought was that the shorthand notation is illogic, since A isn't the same value as AA. The value of A should be 0A if it's hexadecimal. Now I just had to find a standard telling me whether upper- or lowercase representation of A-F should be used and my quest would be over. But I couldn't find any. Today another thought came to my mind. What's best for the page visitor? I began to calculate the cpu cost of the conversion from the string value read by the browser, to a rgb datatype value used to for the actual output on the screen. I figure the shorthand conversion cost more than converting from a six character hexadecimal value. Using the rgb functional notation should be the fastest color value to convert. Anyway - I guess no one use enough colors to make a notable difference and using the rgb functional notation would make the style sheet a few extra bytes per color... I'll stick to lowercase and shorthand for a while. Much ado about nothing - sorry for wasting your time ;-) I use lowercase and shorthand when possible.
