Images that never overflow in HTML & CSS
HTML & CSS interview exercise on Responsive, 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 image is 1200px wide in its attributes and pushes the page sideways on a phone. Make it shrink to the width of its column while keeping its proportions, never upscale beyond its natural size, and render as a block so no stray gap appears under it.
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.
