Btn style fixes

## Whats in this PR
I fixed some btn styling issues for the dashboard. Fixed widths and heights don't work well usually.

### Some notes about front end
I was having a hard time figuring out how the CSS is done in this project. To me it looks like you minified the CSS your self and stuck it into a file? At first I was assuming the CSS in the CSS folder was the CSS that I could make changes in. But it wasn't. 

Any thoughts on this? 

With that said I'm going to be making a lot more Pull requests in the future I think. Refactoring all the css and moving it over to a preprocessor. Kinda shocked its not in LESS or SCSS :scream:
