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


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

// Base class and wrapper
.navbar {

  // 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

  min-height: @navbarHeight;
  padding-left:  20px;
  padding-right: 20px;
  background-color: @navbarBackground;
  border: 1px solid @navbarBorder;

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

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