Centre a card in HTML & CSS
HTML & CSS interview exercise on Flexbox, 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.
The stage is 320px tall and as wide as the page. Centre the card inside it, horizontally and vertically, without stretching it: the card should be only as wide as its text plus padding.
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.
