I am releasing two new themes to the plugins database this evening.
1. Multilayout is a relatively unstyled theme which provides multiple layouts (hence the original name ) from within the theme itself (one line to be uncommented in the layout.php file). It also has additional block regions above and below the main content for greater flexibility in the layout. Multilayout is intended for use as a parent theme rather than for a production site on its own (in a similar way to Standard/Base).
2. Multistyled is a child theme which uses and extends Multilayout to provide a settings page to control both the layout and basic colour scheme, along with a custom css setting box to fine tune the style of the page to match the site requirements. Note: To use multistyled, multilayout must also be installed.
The GitHub link (here) provides a download which includes both themes together, although they are in the Moodle plugins Database separately.
