Visual Studio build everytime JS and CSS changes?

Question

I am relatively new to Visual Studio Development and I was wondering - it seems that everytime I make changes to my JS or CSS in my project - I have to "build" the project again.

Is there any way to simply refresh the browser as opposed to building everytime ? My understanding is that all the files are copied to some temporary directory but I was hoping that I can quickly debug/write JS and CSS within the solution and just refresh the browser to see the changes ?
