Been experimenting with the new MVC 4 for ASP.net. One of the concepts I was having problems with was bundling JavaScript and CSS.

HTML and CSS is not just for web designers. As a web developer you need to able to get your hands dirty with things like HTML and CSS.

Load only the CSS for the current browser to reduce the bandwidth usage.

Was experimenting a little the other day, and found a little hack for CSS, it only effects IE and leaves FF alone.
