Accessibility Tool Block
In order to use the tool, you need to enter the edit mode on any page of your website. Then pull the “Accessibility Tool” block into a global area (i.e. footer or header). As soon as it’s declared in a global area, you can see it on any page of your website without pulling the block into each page. At last, save the page. The “Accessibility Tool” then appears on the upper left corner on your page.
