Hi Robert,
Tough to say. I see a lot of people using a tool like CSS Hero, but they don’t understand CSS. That leads to them having a bunch of custom CSS added to their site, without knowing exactly what does what.
Then some sort of conflict will arise because of the CSS etc..
On the other hand, it can certainly be useful, especially if you use it to learn more about CSS.
Not a terribly helpful answer.. Either way, it’s a good idea to learn some CSS π
