    How does it work?

    Using a <button/>

    If you can use a native HTML element or attribute with the semantics and behavior you require already built in, instead of re-purposing an element and adding an ARIA role, state or property to make it accessible, then do so.

    This means that instead of using a <div/> to create a button we should use the <button/> element.

    The problem with using the <button/> element for creating a button is that in some browsers the <button/> element cannot be used as a flex container.

    To solve both problems at once we need to nest a <div/> inside the <button/>. This <div/> contains the actual button content, like the label and/or an icon.

    Toggle buttons

    In order to indicate to screen readers that a button is a toggle button — meaning that it will keep the active state once clicked — you need to set the aria-pressed attribute accordingly.

    This is automatically done when you specify the isToggled property. If this prop is omitted though we don't set the aria-pressed attribute at all so screen readers to not mistake our button for a toggle button.

    Icon buttons

    In order for screen readers to know what a button does we need to provide a proper label. The <button/> element is able to figure out the aria-label on its own for simple buttons that only contain text.

    For buttons that contain an icon however the default aria-label would also contain the icon, which probably our screenreader does not know how to read out 😉.

    So we need to manually set the aria-label attribute. You need to do so by providing the label prop.

    Disabled buttons

    In order for screen readers to know if your button is disabled we need to set the aria-disabled and disabled attributes on the button. We do so automatically if you set the isDisabled prop to true.
