![]() ![]() ![]() Although aria-haspopup can also be used on role=”button”, we’ll save that for another post on the menu button pattern.Ĭheck out the Live Demo Button, Toggle button, Expanding Button, or Menu Button aria-expanded, aria-pressed, and aria-disabled). Then we’ll test what screen reader and browser combinations are supported when using other ARIA attributes allowed on role=”button.”( i.e. ![]() Continuing on with our series, we’re going to build another accessible ARIA widget: a simple role=”button” UI control. In the last post in the A11y Support Series we talked about ARIA role=”alert” Modal Dialogs. ![]() Adam’s ongoing Accessibility Support Series, where he explains how to build accessible widgets and which screen readers they’re compatible with. aria-hidden or aria-expanded.Building Accessible Buttons with ARIA: A11y Support Series In fact it's not so uncommon that HTML5 don't offer any other alternatives where implementing ARIA would bring significant benefits for the accessibility e.g. Disclaimer: My intention is not to disgrace ARIA but rather its bad ARIA implementations. Often it's better idea to avoid ARIA completely when it's not clear exactly what it does, how it behaves and it won't be tested intensively with all screen readers and browsers (or at least the most common combinations). On top of that each browser and screen reader implement the ARIA support non-uniformly causing the major inconsistencies in the behavior. This is rather common since sighted users and developers are less likely to put extra effort in extensive testing with screen readers while on the other hand ARIA specs and validators are currently far from perfect and even confusing in some cases. Sadly too often ARIA implementations introduce more issues than solutions in terms of accessibility. Don't use ARIA just to have some "cool things in the code" which you don't fully understand. Using ARIA does not necessarily make things better! Easily ARIA can lead to significantly worse accessibility if not implemented and tested properly.ARIA is commonly used to improve the accessibility for screen readers.But aria-labelledby can be used to reference any label already present in the page whereas aria-label is used to communicate the label which i not displayed visuallyĪria-labelledby can also be used to combine two labels for screen reader users Billing AddressĪs a side answer it's worth to note that: But screen readers can understand the purpose of controlīoth aria-label and aria-labelledby is used to communicate the label. There is no visual change in application. aria-label can be used to communicate the label of control to screen reader users Usually search input field does not have visual label (thanks to designers). (Aria is scared of designers too).Īria-label attribute is used to communicate the label to screen reader users. Aria can be used to add content in the code which helps screen reader users understand role, state, label and purpose of the controlĪria does not change anything visually. While navigating through the application, screen reader software announces content to users. Visually impaired users navigate though application using screen reader software like JAWS, NVDA. XĪria is used to improve the user experience of visually impaired users. "Back to the page" will be a more convenient alternative for a screen reader, when "Close" is more significant for someone with no screen reader. In fact aria-label, in this exact situation might be used to give more context to an action:įor instance, blind people do not perceive popups like those of us with good vision, it's like a change of context. It might mean "close", "delete", "cancel", "reduce", a strange cross, a doodle, nothing.ĭespite the fact that the W3C seems to promote the aria-label rather that the title attribute here: in a similar example, you can see that the technology support does not include standard browsers : The "X" is not sufficient enough to give information to the action led by the button (think about someone with no computer knowledge). It won't be of any help to most of the people targetted by the WCAG (except screen reader users), for instance a person with intellectal disabilities. If the aria-label is one tool used by assistive technologies (like screen readers), it is not natively supported on browsers and has no effect on them. In the example you give, you're perfectly right, you have to set the title attribute. ![]()
