We made a code app that is responsive as hell.

We use a mix of CSS Grid and Flexbox. Grid handles the main multi‑column sections and lets them auto‑fit into fewer columns as the viewport narrows, while Flexbox handles horizontal groups that can wrap onto new lines. A few media‑query breakpoints explicitly reduce column counts and stack items on small screens. Typography and spacing use fluid sizing so text and padding scale smoothly instead of jumping.

My computer is overheating. Even testing responsiveness lags.
