// Clearfix
// Source: http://nicolasgallagher.com/micro-clearfix-hack/
//
// For modern browsers
// 1. The space content is one way to avoid an Opera bug when the
// contenteditable attribute is included anywhere else in the document.
// Otherwise it causes space to appear at the top and bottom of elements
// that are clearfixed.
// 2. The use of `table` rather than `block` is only necessary if using
// `:before` to contain the top-margins of child elements.
.clearfix() {
&:before,
&:after {
content: ' '; // 1
display: table; // 2
}
&:after {
clear: both;
}
}
// WebKit-style focus
.tab-focus() {
outline: none;
}
// Center-align a block level element
.center-block() {
display: block;
margin-left: auto;
margin-right: auto;
}
// Sizing shortcuts
.size(@width; @height) {
width: @width;
height: @height;
}
.square(@size) {
.size(@size; @size);
}
// Placeholder text
.placeholder(@color: @input-color-placeholder) {
&::-moz-placeholder {
color: @color; // Firefox
opacity: 1;
} // See https://github.com/twbs/bootstrap/pull/11526
&:-ms-input-placeholder {
color: @color;
} // Internet Explorer 10+
&::-webkit-input-placeholder {

} // Safari and Chrome
}
// Text overflow
// Requires inline-block or block for proper styling
.text-overflow() {
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
}
// CSS image replacement
//
// Heads up! v3 launched with with only `.hide-text()`, but per our pattern for
// mixins being reused as classes with the same name, this doesn't hold up. As
// of v3.0.1 we have added `.text-hide()` and deprecated `.hide-text()`. Note
// that we cannot chain the mixins together in Less, so they are repeated.
//
// Source: https://github.com/h5bp/html5-boilerplate/commit/aa0396eae757
