< p > When using button classes on < code > < a> < / code > elements that are used to trigger in-page functionality (like collapsing content), rather than linking to new pages or sections within the current page, these links should be given a < code > role=" button" < / code > to appropriately convey their purpose to assistive technologies such as screen readers.< / p >

Some of the button styles use a relatively light foreground color, and should only be used on a dark background in order to have sufficient contrast.

< p > To cover cases where you have to keep the < code > href< / code > attribute on a disabled link, the < code > .disabled< / code > class uses < code > pointer-events: none< / code > to try to disable the link functionality of < code > < a> < / code > s. Note that this CSS property is not yet standardized for HTML, but all modern browsers support it. In addition, even in browsers that do support < code > pointer-events: none< / code > , keyboard navigation remains unaffected, meaning that sighted keyboard users and users of assistive technologies will still be able to activate these links. So to be safe, in addition to < code > aria-disabled=" true" < / code > , also include a < code > tabindex=" -1" < / code > attribute on these links to prevent them from receiving keyboard focus, and use custom JavaScript to disable their functionality altogether.< / p >

Visually, these toggle buttons are identical to the < a href = "/docs/5.2/forms/checks-radios/#checkbox-toggle-buttons" > checkbox toggle buttons< / a > . However, they are conveyed differently by assistive technologies: the checkbox toggles will be announced by screen readers as “ checked” /“ not checked” (since, despite their appearance, they are fundamentally still checkboxes), whereas these toggle buttons will be announced as “ button” /“ button pressed” . The choice between these two approaches will depend on the type of toggle you are creating, and whether or not the toggle will make sense to users when announced as a checkbox or as an actual button.
