// UTILITY MIXINS
// --------------------------------------------------

// Clearfix
// --------
// For clearing floats like a boss h5bp.com/q
div[class*="dfMc-"]{
   .clearfix{
      *zoom: 1;
      &:before,
         &:after {
         display: table;
         content: "";
         // Fixes Opera/contenteditable bug:

      line-height: 0;
   }
   &:after {
      clear: both;
   }
}
// Webkit-style focus
// ------------------
.tab-focus() {
   // Default
   outline: thin dotted #333;
   // Webkit
   outline: 5px auto -webkit-focus-ring-color;
   outline-offset: -2px;
}

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

// IE7 inline-block
// ----------------
.ie7-inline-block() {
   *display: inline; /* IE7 inline-block hack */
   *zoom: 1;
}

// IE7 likes to collapse whitespace on either side of the inline-block elements.
// Ems because we're attempting to match the width of a space character. Left
// version is for form buttons, which typically come after other elements, and
// right version is for icons, which come before. Applying both is ok, but it will
// mean that space between those elements will be .6em (~2 space characters) in IE7,
// instead of the 1 space in other browsers.
.ie7-restore-left-whitespace() {
   *margin-left: .3em;

   &:first-child {
      *margin-left: 0;
   }
}

.ie7-restore-right-whitespace() {
   *margin-right: .3em;
}

// Sizing shortcuts
// -------------------------
.size(@height, @width) {
   width: @width;
   height: @height;
}
.square(@size) {
   .size(@size, @size);
}

// Placeholder text
// -------------------------
.placeholder(@color: @placeholderText) {
   &:-moz-placeholder {
      color: @color;
   }
   &:-ms-input-placeholder {
      color: @color;
   }
   &::-webkit-input-placeholder {
      color: @color;
   }
}

// Text overflow
// -------------------------
// Requires inline-block or block for proper styling
.text-overflow() {
   overflow: hidden;
   text-overflow: ellipsis;
   white-space: nowrap;
}

// CSS image replacement
// -------------------------
// Source: https://github.com/h5bp/html5-boilerplate/commit/aa0396eae757
