// Navbar vertical align
//
// Vertically center elements in the navbar.
// Example: an element has a height of 30px, so write out `.navbar-vertical-align(30px);` to calculate the appropriate top margin.

  margin-top: (($navbar-height - $element-height) * 0.5);
  margin-bottom: (($navbar-height - $element-height) * 0.5);
