CSS assessment | SovranCode

First make decisions across all 16 lessons, then prove you can apply the core layout and accessibility techniques in code.

PART 2 · APPLIED CSS

Make three interfaces pass practical checks.

The checks inspect the CSS you wrote. Passing them confirms the requested rules are present; inspect the preview yourself for visual quality and accessibility.

Build a resilient card grid

Complete the stylesheet so the cards form responsive columns without overflowing a narrow viewport.

Grid · minmax() · box sizing · intrinsic sizing

Automatic requirements

.cards uses CSS Grid.
Tracks use repeat() and minmax() for responsive columns.
The grid has a nonzero gap.
Long card text can wrap instead of forcing overflow.

Result

Practice here: edit your HTML or CSS and compare the result. Live preview updates after a short pause. Scripts, form submissions, and external resources are blocked. Wide previews scroll inside this panel. Running code does not grade or save it; use the separate learning and save controls.
