//
// # .lib-clearfix()
//
//  The <code>.lib-clearfix()</code> mixin is a modern solution for healing container`s height which have floated elements. Also its applying prevents top-margins from collapsing.
//

.example-clearfix-container-1 {
    border: 1px solid #f00;
}

.example-clearfix-container-2 {
    .lib-clearfix();
    border: 1px solid #0f0;
}

.example-clearfix-item.left {
    float: left;
}
.example-clearfix-item.right {
    float: right;
}

// Container with floated child elements without <code>.lib-clearfix()</code>
//  ```
//  <div class="example-clearfix-container-1">
//      <div class="example-clearfix-item left">
//          Float left
//      </div>
//      <div class="example-clearfix-item right">
//          Float right
//      </div>
//  </div>
//  ```

// Container with floated child elements with <code>.lib-clearfix()</code>
//  ```
//  <div class="example-clearfix-container-2">
//      <div class="example-clearfix-item left">
//          Float left
//      </div>
//      <div class="example-clearfix-item right">
//          Float right
//      </div>
//  </div>
//  ```

// # .lib-visibility-hidden()
//
//  The <code>.lib-visibility-hidden()()</code> mixin changes element`s visibility to hidden and height to 0.
//

.example-visibility-hidden {
    .lib-visibility-hidden();
}

//
//  This is a block with applied <code>.lib-visibility-hidden()</code> mixin.

//
//  ```
//  <div class="example-visibility-hidden">
//      <div>
//          This is hidden text
//      </div>
//  </div>
//  ```

// # .lib-visually-hidden()
//
//  The <code>.lib-visually-hidden()</code> mixin safely hides the element for accessibility reasons.
//

.example-visually-hidden-1 {
    .lib-visually-hidden();
}

//
//  This is a block with applied <code>.lib-visually-hidden()</code> mixin.

//
//  ```
//  <div class="example-visually-hidden-1">
//      <div>
//          This is hidden text
//      </div>
//  </div>
//  ```

// # .lib-visually-hidden-reset()
//
//  The <code>.lib-visually-hidden-reset()</code> mixin resets hidden visibility and makes element again visible.
//

.example-visually-hidden-2 {
    background: #fdf0d5;
    padding: 5px;
    .lib-visually-hidden();
}

.example-visually-hidden-2 {
    .lib-visually-hidden-reset();
}

//
//  This is a block with applied <code>.lib-visually-hidden-reset()</code> mixin after <code>.lib-visually-hidden()</code> applying.

//
//  ```
//  <div class="example-visually-hidden-2">
//      <div>
//          The text is visible again
//      </div>
//  </div>
//  ```

// # .lib-css()
//
//  The <code>.lib-css()</code> mixin is used to set any css property if there is a value passed to it by a variable. Also <code>.lib-css()</code> can add -ms-, -webkit- and -moz- prefixes if needed.
//

.example-css-container {
    .lib-css(padding, @indent__base);
    .lib-css(background, @secondary__color);
}

//
//  If the variable is set to <code>false</code>, the <code>.lib-css()</code> mixin will add nothing to the code.
//
//  ```
//  <div class="example-css-container">
//      Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt..
//  </div>
