// NOTES ON LESS (tracking learnings so we don't forget)
// =============================================================================
// * We want this file to continue to be accessible by people who don't know
//   LESS but know CSS. This means finding the balance between using the most
//   valuable LESS features (e.g. variables) and keeping it looking like CSS.
//   So it's best to avoid advanced LESS features like conditional statements.
//   (we're using one for the big play button position because that's a hot
//   topic)
//
// * We care about the readability of the CSS output of LESS, which means we
//   have to be careful about what features of LESS we use. (if you're building
//   your own skin this may not apply)
//     1. Comments inside of rules (strangely) have an extra line added after
//        them in the CSS output. To avoid this we can add a LESS comment after
//        the CSS comment.
//          /* comment *///
//
//     2. In a rule with nested rules, any comments outside of a rule are moved
//        to the top of the parent rule. i.e. it might look like:
//          /* title of rule 1 */
//          /* title of rule 2 */
//          .rule1 {}
//          .rule2 {}
//        This is why we aren't using nested rules inside of the
//        vjs-default-skin class.
