A data table done right 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.
Build a table of three languages (JavaScript, Python, Rust) with two columns of facts each: the year it appeared (1995, 1991, 2010) and its typing (dynamic, dynamic, static). Give it a caption, a header row whose cells are marked as column headers, and make the language name in each row a row header.
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.
