Accessibility Block for Moodle |
|||
|
|||
Provides options for changing text size and colour scheme. Settings can be saved to persist between sessions. Colour settings can be defined at the block instance level (Block instance configuration). |
|||
|
|||
Also integrates ATbar from Southampton University ECS http://www.atbar.org. Code used under BSD Licence. |
|||
|
|||
To install, place all files in /blocks/accessibility/ directory and visit /admin/index.php in your browser. To achieve block appearance throughout entire Moodle site (so-called "Sticky block") once the plugin is installed into Moodle, it's recommended to add its instance onto the Moodle homepage (/index.php). Homepage instance of the block enables "Page contexts" option in block instance configuration to be set to "Display throughout entire site". |
