Test your skills: WAI-ARIA - Learn web development 编辑

This aim of this skill test is to assess whether you've understood our WAI-ARIA basics article.

Note: You can try out solutions in the interactive editors below, however it may be helpful to download the code and use an online tool such as CodePen, jsFiddle, or Glitch to work on the tasks.

If you get stuck, then ask us for help — see the Assessment or further help section at the bottom of this page.

WAI-ARIA 1

In our first ARIA task, we present you with a section of non-semantic markup, which is obviously meant to be a list. Assuming you are not able to change the elements used, how can you allow screenreader users to recognize this as a list?

Try updating the live code below to recreate the finished example:

WAI-ARIA 2

In our second WAI-ARIA task, we present a simple search form, and we want you to add in a couple of WAI-ARIA features to improve its accessibility:

1. How can you allow the search form to be called out as a separate landmark on the page by screenreaders, to make it easily findable?
2. How can you give the search input a suitable label, without explicitly adding a visible text label to the DOM?

WAI-ARIA 3

For this final WAI-ARIA task, we return to an example we previously saw in the CSS and JavaScript skilltest. As before, we have a simple app that presents a list of animal names. Clicking one of the animal names causes a further description of that animal to appear in a box below the list. Here, we are starting with a mouse- and keyboard-accessible version.  

The problem we have now is that when the DOM changes to show a new decription, screenreaders cannot see what has changed. Can you update it so that description changes are annouced by the screenreader?

Assessment or further help

You can practice these examples in the Interactive Editors above.

If you would like your work assessed, or are stuck and want to ask for help:

1. Put your work into an online shareable editor such as CodePen, jsFiddle, or Glitch. You can write the code yourself, or use the starting point files linked to in the above sections.
2. Write a post asking for assessment and/or help at the MDN Discourse forum Learning category. Your post should include:
   • A descriptive title such as "Assessment wanted for WAI-ARIA 1 skill test".
   • Details of what you have already tried, and what you would like us to do, e.g. if you are stuck and need help, or want an assessment.
   • A link to the example you want assessed or need help with, in an online shareable editor (as mentioned in step 1 above). This is a good practice to get into — it's very hard to help someone with a coding problem if you can't see their code.
   • A link to the actual task or assessment page, so we can find the question you want help with.
