// Normalize form controls
//
// While most of our form styles require extra classes, some basic normalization
// is required to ensure optimum display with or without those classes to better
// address browser inconsistencies.

// Override content-box in Normalize (* isn't specific enough)

// Position radios and checkboxes better
input[type="radio"],
input[type="checkbox"] {
  margin: 4px 0 0;

  line-height: normal;
}

// Set the height of file controls to match text inputs
input[type="file"] {
  display: block;
}

// Make range inputs behave like textual form controls
input[type="range"] {
  display: block;
  width: 100%;
}

// Make multiple select elements height not fixed
select[multiple],
select[size] {
  height: auto;

// Focus for file, radio, and checkbox
input[type="file"]:focus,
input[type="radio"]:focus,
input[type="checkbox"]:focus {
  .tab-focus();

// Common form controls

.form-control {

  // Disabled and read-only inputs
  //
  // HTML5 says that controls under a fieldset > legend:first-child won't be
  // disabled if the fieldset is disabled. Due to implementation difficulty, we
  // don't honor that edge case; we style them as disabled anyway.

// Form groups
//
// Designed to help with the organization and spacing of vertical forms. For
// horizontal forms, use the predefined grid classes.
