Description

  <link href="../base1/cockpit.css" type="text/css" rel="stylesheet">
  @import url('../base1/cockpit.css');

These are the standard Cockpit CSS stylesheets. They automatically pull in the PatternFly and Bootstrap styles that they depend on. When you bring these into your component, do not include patternfly.css explicitly as well.

The exact styles available beyond what's in PatternFly is not yet documented or public API.
