I am using a custom css solution developed by someone else in my Umbraco site. The problem is that the css is hard to understand and if changes need to be made, I can't do it. In addition, this makes the html markup hard to modify as well. Also, I can't use the grid currently because the css makes it look very strange. I wanted to start porting over my website to mainly use bootstrap and possibly use fanoe as the starting kit. Does anyone have any pointers on doing this or what the best approach would be?
