/*
 * Brackets Default Theme
 *
 * Defines all the variables that one can configure in a theme. This should
 * contain all variables / mixins for UI styling that we want to be able to
 * change in a theme.
 *
 * Throughout the rest of the LESS files we should _only_ use color
 * variable names that are on the LHS of the list below. So, if we
 * need a new color for some UI element, we should add a variable
 * in this file.
 */

/*
  This LESS file contains code coloring configuration and the default colors specified
  in this files have been defined globaly. Which means if a selector defined below is
  being used in multiple document modes then all of those tokens will be colored using
  the color value specified here. In order to control the number of unique colors used,
  selectors are grouped together to distribute a limited number of colors across all
  possible tokens in different document modes.

  For example consider the following HTML snippet -
   ----------------------------------
    <div>
        My Sample content
    </div>
   ----------------------------------

  And the following CSS snippet -
   ----------------------------------
    div {
        color: #00f;
    }
   ----------------------------------

  In CC 2017, in both HTML and CSS doc modes 'div' has been assigned '.cm-tag' selector.
  This implies that if in this LESS file the selector group containing '.cm-tag' is assigned
  a color value '#446fbd', the tag name 'div' in HTML and the selector name 'div' in CSS will
  have the same color. For a more detailed understanding of tokens and selectors being used in
  different language modes, please go though the follwoing helpx page section -

  (https://helpx.adobe.com/dreamweaver/using/customize-code-coloring.html#Understandingselectors)

  However it's possible to specify different color values for these selectors targetting
  different language modes. What needs to be done is identify the tokens what's being used
  in a particular doc mode and target the corresponding selectors by nesting them under the
  MODE selector.

  For example let's take the snippets and case described above. If we want to override the
  default color of tag only in HTML mode, we need to append this selector after the "custom" marker
  in this LESS file.

   ----------------------------------------------
   .HTML {
        .cm-tag {
            color: <custom color here>;
        }
   }
   ----------------------------------------------

   This example can be expanded to include individual selectors or certain selectors grouped together.

   These are the list of popular language modes along with the file extensions which they are associated with. Any of these modes can be used as parent selectors and then the individual token color can be
   nested inside to make sure that we change only the targetted modes coloring.

    CodeMirror's use of descendant selectors for certain styling causes problems when editors are
    nested because, for items in the inner editor, the left-hand clause in the selector will now
    match either the actual containing CodeMirror instance *OR* the outer "host" CodeMirror instance.

    TODO (issue #324): We'll still have problems if editors can be nested more than one level deep,
    or if any other descendant-selector-driven CM styles can differ between inner & outer editors
    (potential problem areas include line wrap and coloring theme: basically, anything in codemirror.css
    that uses a descandant selector where the CSS class name to the left of the space is something
    other than a vanilla .CodeMirror)
