How to create a custom button that opens the accessibility interface
It's very simple.
All you have to do is hide our button (using CSS), choose your own element that you want to replace with the current accessibility button, and add the following HTML attribute:
data-acsb = "trigger"
For this matter, here is an example of a simple element that, with the sentence above, becomes the accessibility button:
< span data-acsb="trigger">Accessibility </ span>
