Summary
A simple plugin which allow web developer or those who familiar with CSS to inject own custom CSS into any website to overwrite default styling, such as font-size, font-color, and so on.
User reviews
Throws all kinds of errors for no reason, even with basic elements like #header.
It doesn't have any formatting aids either, though I suppose if all you care about is size that's not a dealbreaker.
