// Navbars (Redux)
// --------------------------------------------------


// COMMON STYLES
// -------------

// Base class and wrapper
.navbar {
  overflow: visible;
  margin-bottom: $baseLineHeight;

  // Fix for IE7's bad z-indexing so dropdowns don't appear below content that follows the navbar
  *position: relative;
  *z-index: 2;
}

// Inner for background effects
// Gradient is applied to its own element because overflow visible is not honored by IE when filter is present
.navbar-inner {
  min-height: $navbarHeight;
  // padding-left:  20px;
  // padding-right: 20px;
 //@include gradient-vertical($navbarBackgroundHighlight, $navbarBackground);
  //border: 1px solid $navbarBorder;
  //@include border-radius($baseBorderRadius);
  //@include box-shadow(0 1px 4px rgba(0,0,0,.065));

  // Prevent floats from breaking the navbar
  @include clearfix();
}

// Set width to auto for default container
// We then reset it for fixed navbars in the #gridSystem mixin
.navbar .container {
  width: auto;
}

// Override the default collapsed state
.nav-collapse.collapse {
  height: auto;
  overflow: visible;
}
