Some elements may also have a state, which conveys their current status. For instance, may have a value that reflects whatever the user has typed into the text field. 'Sign Up, button.' The algorithm that determines an element's name factors in things like if there is any text content inside the element, whether or not it has attributes such as title or placeholder, whether or not the element is associated with an actual element, and if the element has any ARIA attributes such as aria-label and aria-labelledby. Screen readers typically announce an element's name followed by its role, e.g. 'button,' 'input,' or even just 'group' for things like div's and span's.Īn element's name is its computed label. Generally speaking, every HTML element will have some of the following semantic properties:Īn element's role describes its type, i.e. Semantic properties and the accessibility tree # For example, replace a that's acting like a button with an actual. The simplest and often best solution to this problem is to avoid custom interactive controls altogether. The is announced as a 'button,' a much stronger signal to the user that it's something they can interact with.

A is just a generic grouping element, so a screen reader only announces the text content of the. Using CSS, it's possible to style the and elements so they convey the same visual affordances, but the two experiences are very different when using a screen reader. The easiest way of conveying proper semantics is to use semantically rich HTML elements. This non-visual exposure of a UI element's affordances is called its semantics. Therefore, you need to make sure that your UI is constructed in a way that can convey these same affordances to assistive technology. For instance, you might give a button a drop shadow and border so that it resembles an actual button in the real world.īut if a user is unable to see the screen, then these visual affordances will not be conveyed to them. When we build graphical user interfaces, we use things like CSS to add visual affordances to our UI. It has a handle, and because you've seen other objects in the world with similar handles, you can infer how you should pick it up and operate it.

This teapot doesn't need an instruction manual instead, its physical design conveys to the user how it should be operated. A classic example is the teapot: A teapot's handle is a natural affordance. An affordance is any object that offers, or affords, its user the opportunity to perform an action. But what are semantics, and how do screen readers use them? Affordances and semantics #īefore diving into semantics, it's helpful to understand another term: affordances. Have you ever stopped to wonder how assistive technology, such as a screen reader, knows what to announce to users? The answer is that these technologies rely on developers marking up their pages with semantic HTML. Semantic properties and the accessibility tree.
