Inline meaning, not inline looks 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 one paragraph that says: "The DOM is what the browser builds from your markup. Never mutate it in a loop; batch the work. Run npm test before you push." Mark up DOM as an abbreviation with its expansion in a title, "Never" as strong importance, "batch the work" as stress emphasis, "npm test" as code, and "before you push" as highlighted text. No b, i, font or u elements.
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.
