This will make the content degrade gracefully, and the tooltip to be open if scripts are not working. We are only going to set the initial state when the page loads. Now we will not need to change their CSS class in the code, only the value of aria-hidden. We will use CSS selectors to show and hide the tooltip based on the aria-hidden value. So we are going to use aria-hidden as our state. The tooltip changes from being non-visible to visible. Step 3: Set the initial statesĪ good rule of thumb is that elements that change how they look often have states that can change at the same time. Note that it is always worth looking at any requirements such as required states, and supported states for your roles before deciding what properties and states you need. We use aria-describedby to solve this type of problem. The relationship between the tooltip and the form control is not clear from the DOM. We want to make sure the structure, relationships between elements and groups, properties and labels are all clear in the code. The only thing that needs a role is the tooltip.Īlso known as User ID Step 2: Set properties and important relationships Our form uses HTML standard form controls so we do not need form control roles as well. All controls should receive focus via tabbing though the keyboard. Events can be triggered though the keyboard, and it should be intuitive to the user. Make sure widgets are keyboard accessible and focus works predictably.Alert users to what each element is doing: The state (such as checked).Alert users to their properties and important relationships (such as disabled, required,and other labels).Alert users to what each elements is: Their role (such as checkbox).
