// Mixins.less
// Snippets of reusable CSS to develop faster and keep code readable
// -----------------------------------------------------------------


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

// Clearfix
// --------
// For clearing floats like a boss h5bp.com/q
.clearfix() {
  *zoom: 1;
  &:before,
  &:after {
    display: table;
    content: "";
  }
  &:after {
    clear: both;
  }
}

// Webkit-style focus
// ------------------
.tab-focus() {
  // Default
  outline: thin dotted;
  // 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;

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

// Sizing shortcuts
// -------------------------
.size(@height: 5px, @width: 5px) {
  width: @width;
  height: @height;
}
.square(@size: 5px) {
  .size(@size, @size);
}

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



// FONTS
