// “Clearfix Reloaded” Mixin
// The mixin is used on a container with floating children.
// Margin collapsing is a feature, not a bug, hence relying on `display: block` as default.
// With `.mixin-clearfix( @collapse: false; );` you call it to let `margin`s not collapse.
// See https://www.cssmojo.com/the-very-latest-clearfix-reloaded/
// In future we might replace the `&:after` pseudo-element with
// `display: flow-root;` altogether.
// Support: Firefox 3.5+, Safari 4+, Chrome, Opera 15+, IE 8+
