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.

    If you encounter this issue, you can change the settings in each individual quiz. Under "appearance" select "show blocks during attempt". This enables users to change the accessibility settings at the quiz level.

    Hi, Thanks for this great accessibility block!
    Is there a version compatible with Moodle 3.4? or Moodle 3.5?

    Although not officially released, we use it on v3.5.2 and it works as expected, if that helps.

    @cristina galofre We use 3.5.3 with Boost at the moment and the Accessibility block works fine for our site. However, the ATbar (see ) is overlapped by the Nav drawer in the Boost theme.
    Word of caution: Using custom CSS to style your Moodle site does ~not~ play well with ATbar either. (As admin: go to Dashboard / Site administration / Appearance / Themes / Boost, then Advanced settings.)
    I'm using the following relevant custom styling; it works fine for screens / internet browsers wider than about 780px. But the "move ATbar buttons to the right a bit" fix causes them to overlap each other on smaller screens.

    Raw initial SCSS
    html, body {
    font-size: 16px;

    .breadcrumb-item {
    font-size: 1.125rem;

    .instancename {
    font-size: 1.25rem;

    .sectionname {
    font-size: 1.625rem;

    .mr-2 {
    font-size: 1.5rem;

    #page-content {
    font-size: 1.125rem;

    Raw SCSS
    body div#sbarGhost, body div#sbar {
    top: 50px !important;

    body div#sbar {
    a#sbarlogo {
    position: relative;
    left: 140px !important;
    margin-left: 140px !important;
    div#at-btn-ftw, div#at-btn-resizeUp, div#at-btn-resizeDown, div#at-btn-fontSettings, div#at-btn-spell, div#at-btn-dictionary, div#at-btn-tts, div#at-btn-wordprediction, div#at-btn-css, div#at-btn-overlay {
    position: relative;
    left: 140px !important;

    Hi. Is there any date for this block to be updated contemplating version 3.6 of Moodle?

    Hi. Firstly, this is a wonderful plugin. Is there a workaround to add French to the text to speech functionality?

    Hi Hittesh
    This is a great plugin, and still works on 3.6. We are really keen to see it continue to be developed. Can I have a conversation about how we can help see an update to this.
    I have sent a contact request.

    In my opinion this plugin might or might not be useful anymore. Could be worthwhile to verify directly with the users whether such tools are even useful or used nowadays?

    It has been long years since the plugin was initially released and surely back then there was a need and common practice to have such tools improving the accessibility on the website. But since then the whole Web has changed, the websites, browsers, browsing devices, assistive technology and even the accessibility guidelines.

    Here is a quote from well accepted accessibility resource WebAIM describing it as a bad practice: "All browsers allow the sizing or scaling of the page content - why duplicate this browser functionality?" >

    This plugin is really important as it helps students who are visually impaired to see moodle lessons. It has not been updated for some time. Can it be updated to allow more colour overlays to be set as you can only create 3 and we need 5 colours ways? During lockdown this is very important, I wonder if someone can update this plugin to allow up to 5 or 6 colours to pick from. The size is brilliant, I wonder if there could be a button to change the font as well, as some styles are seen as being easier to read than others. Finally, some web browsers read out the content of the page. I wonder if a button to read out the page would be possible? Thank you so much.

    I know you have a reader but moodle appears on our site in a I-frame so the when they click the button the reading functions do not appear.

    This plugin has been tested and works perfectly on Moodle 3.8. Without it, students with special needs would be unable to gain access to work. I cannot find another plugin similar in the moodle directory. This plugin definitely needs updating.

    What do you mean by "it's recommended to add its instance onto the Moodle homepage (/index.php)"?
    What do I have to do in index.php?
    If I have to change the file, when I update Moodle, the changes will be lost.
