Google and Facebook buttons are available featuring each company's respective brand color. They are used on the user login and registration pages.
You can create more custom buttons by adding a new color variable in the _variables.scss file and then using the Bootstrap button variant mixin to create a new style, as demonstrated in the _buttons.scss file.
Works with any button colors, just use the .btn-icon-split class and the markup in the examples below. The examples below also use the .text-white-50 helper class on the icons for additional styling, but it is not required.
Also works with small and large button classes!
