Importance Of Lists

#a11y #testing #screenreader

Semantic structure is the foundation for accessible markup, as they properly convey information to the user through the accessibility API via screen readers.

In this article, let's take a closer look at how a screen reader interacts with a list, provided it is written with correct semantic HTML.

Access lists with a screen reader

When the screen reader encounters a list, it announces that it is a list and how many elements the list contains.

Depending on the type of list, the screen reader reads the list slightly differently.

Ordered lists

Ordered lists are written with a parent element <ol> containing child elements of <li>.
The screen reader announces e.g. list, 3 items, 1 list-element 1, 2 list-element 2, 3 list-element 3.

Unordered lists

Unordered lists are written with a parent element <ul> containing child elements of <li>.
The screen reader announces e.g. list, 3 items, bullet list-element 1, bullet list-element 2, bullet list-element 3.

Description lists

Description lists are written with a parent element <dl>, a term element <dt> containing child elements of <dd>.
The screen reader announces e.g. description list, 3 items, term, term element, child element 1, group, child element 1, ... .

Access lists with a screen reader (live demo)

I am using VoiceOver on the MacBook Air. I tried it in Safari, Chrome and Firefox, it worked the same everywhere.

The Control + Option combination is often referred to as VO.

Let's take a look on how I went through the lists in this example. To read the page use VO + A, to stop it use Control.

You can find the example to test it on your own on codepen.

Methods	Screen Reader	Browser	Command
Show All Lists	VoiceOver	Safari	`Control + Option + U` (to open rotor), but `List` was not shown in the web rotor, even though I selected the item in the settings
Navigate from One List Item to the Next	VoiceOver	Safari	`Control + Option + Command + X`

*I did research on other browser/screen reader combination. I found out that with JAWS with Chrome or Firefox you can do Control + L to show all lists.
