The block allows users to customise Moodle to their visual needs.  It supports changing of text sizes and colour schemes.  Customisations save to the user's session, allowing them to persist between pages, and can also be saved to the database allowing them to apply permanently.

The block also integrates ATBar from Southampton University ECS. This provides extra tools and customisation options, including dictionary lookup and Text-to-speech.  Visual customisations performed with ATBar don't currently persist, and can be used as well as or instead of the block's own customisations.

Please dont report bugs here

If you experience an error with the block, or would like to request a feature, please use the "Bug Tracker" link below.

    Hello! I'm trying to add a modification to the plugin that allows you to apply the visual changes also to the content of the "Interactive Book" (H5P module). I tried to replicate in "userstyle.php" to apply from the class ,h5p-iframe-wrapper". But I didn't succeed. Someone there who tried to customize the plugin, managed to make similar changes? Could you guide me? I appreciate it right now.

    When you click A- or A+, it doesn't do anything. Do you know how to solve this problem?
    Thanks in advance

    @Junior Goude, if you want the plugin to show up on every page you need to add it as a site-wide block after enabling if not then it needs to be added to the pages where you want it. See:

    We have investigated a bug where the size does not increase or decrease sometimes. It appears to work when you log in as admin but does not work when you log in as a student. So the font size increase and decrease does not always work for a student but will if you are an admin, it appears to be fine. I hope this helps you to solve the issue. Cheers.

    Hi Al, we have retested internally and we can't replicate your findings as it's working fine on our test sites. Can you confirm if this issue still happens when you test with core Boost theme?

    Hi Byron, as @Tim Williams kindly already commented above (thanks!), to add the plugin on all pages, if you want the plugin to show up on every page you need to add it as a site-wide block after enabling if not then it needs to be added to the pages where you want it. See:

    Hi, this is wonderful. Likewise, can I check on the Moodle 4.0 ETA?

    Dear developers,
    You are awesome!
    We use this plugin around 4 years and we never had any issues.
    However, recently, we updated to moodle 4 and we noticed that the accessibility block stoped working correctly with the navbar superpositioning it. Are you intending to fix this behavior any time soon? We have several students with special needs that rely on this plugin. It would be most appreciated to have it back to normal as soon as possible.
    Thank you in advance.
    Prof. Marotta.

    This is really wonderful plugin and we all can't wait to see a new version of it for Moodle 4. Also it would be very awesome if this block would work for unauthenticated users on home page
