Alt text that says the right amount in HTML & CSS
HTML & CSS interview exercise on Accessibility, difficulty 1 of 3. Solve it in the editor beside a worked example, or cold in Interview mode with the example hidden; the tests run the moment you do.
A header with three images: the company logo (the link home, so its alt names the company: "Acme"), a chart that shows sign-ups doubling in October (describe that in the alt), and a purely decorative divider image that screen readers should skip. Every img needs an alt attribute; the decorative one an empty one.
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Interview mode hides the example: solve it from memory, without the hint or the solution, and it counts as solved cold. Progress is saved in your browser, and in your account if you sign in.
