When the default is true

TEXT SIZE MANIPULATION APPROACHES:

If text increase / decrease isn't working for your size your probably not using responsive font size units (such as em, rem etc.).
In that case you can initialize the accessibility tool like this:
new Accessibility({textPixelMode: true})

ANIMATIONS:

Cancel all buttons animations:
new Accessibility({animations: {buttons: false}})

POSITIONING:

You can position the accessibility icon in any place on the screen. The default position is bottom right: var options = {     icon: {         position: {             bottom: { size: 50, units: 'px' },             right: { size: 0, units: 'px' },             type: 'fixed'         }     } } new Accessibility(options); But you can also position the icon in the upper left corner of the screen and cancel the fixed positioning: var options = {     icon: {
        position: {             top: { size: 2, units: 'vh' },             left: { size: 2, units: '%' },             type: 'absolute'         }     } } new Accessibility(options);
