How to use BBG
It's easy. Really. Just enter the css class you want to assign to your new button style and play with the different button colors to update the live previews in the right.
When you are ready, copy the code below and add it to your page below bootstrap.min.css to use the button.
What if I need to...
Sorry, but this is a very simple tool to do a very simple thing: generate button syles. If you need to customize other Boostrap aspects, take a look at the official customization tool.
