He means do it well. There's a lot to doing CSS well, and frankly I just don't have any interest in learning all the ins and outs. It's not a fun platform to work in, it's very fiddly, and it's not exactly programming either.

There's an art-form to doing amazing pixel perfect web designs, and I really respect the people who are good at it. That's not me though, and it's never going to be me.
