// Mixins
// --------------------------------------------------


// Utilities
// -------------------------

// 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.
@mixin clearfix() {
  &:before,
  &:after {
    content: " "; /* 1 */
    display: table; /* 2 */
  }
  &:after {
    clear: both;
  }
}

// WebKit-style focus
@mixin tab-focus() {
  // Default
  outline: thin dotted #333;
  // WebKit
  outline: 5px auto -webkit-focus-ring-color;
  outline-offset: -2px;
}

// Center-align a block level element
@mixin center-block() {
  display: block;
  margin-left: auto;
  margin-right: auto;
}

// Sizing shortcuts
@mixin size($width, $height) {
  width: $width;
  height: $height;
}
@mixin square($size) {
  @include size($size, $size);
}

// Placeholder text
@mixin placeholder($color: $input-color-placeholder) {
  &:-moz-placeholder            { color: $color; } // Firefox 4-18
  &::-moz-placeholder           { color: $color; } // Firefox 19+
  &:-ms-input-placeholder       { color: $color; } // Internet Explorer 10+
  &::-webkit-input-placeholder  { color: $color; } // Safari and Chrome
}

// Text overflow
// Requires inline-block or block for proper styling
@mixin 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
