Lists that mean something in HTML & CSS
HTML & CSS interview exercise on Semantic HTML, difficulty 2 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.
Write a glossary of three terms (HTML, CSS, DOM) with a one-line definition each, as a description list. Below it, a to-do list with three items where the second item has two sub-items of its own. No line breaks or dashes to fake the structure.
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.
