Advantages

• Most of the time you will only need one color to create a button.
• Even though Buttono is following the BEM methodology, you can still use it with all other conventions.
• The buttons you create with Buttono will look exactly the same in all modern browsers.
• No need to worry about focus styles for accessibility.
• Thanks to Buttono’s flexible structure you can configure it for any situation.

Browser support

It does not use any tool for browser support. Using autoprefixer for browser support is up to you. I strongly recommend you consider using normalize.css to avoid inconsistency.
