 //

 // 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() {

   // 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;

 }

 // 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 4-18

   &::-moz-placeholder           { color: @color;   // Firefox 19+

                                   opacity: 1; } // See https://github.com/twbs/bootstrap/pull/11526

   &:-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

 .text-overflow() {

   overflow: hidden;

   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

 // Deprecated as of v3.0.1 (will be removed in v4)
