Ever built a perfect CSS Grid layout on a desktop screen only to have it blow past the viewport on a phone? In this episode, Lucas and Luna dig into a specific example: a three-column dashboard grid that looks fine at 1200 pixels wide but triggers a horizontal scrollbar at 480 pixels. They trace the root cause to a common combination of fixed column widths, implicit grid tracks, and the min-width default on grid items. Lucas walks through the actual CSS properties involved: grid-template-columns with minmax, the implicit min-width of 300 pixels on grid children, and how overflow-x: hidden only masks the symptom. They also show how to prevent the overflow using minmax(0, 1fr) and explicit min-width: 0. By the end you will know exactly why your grid overflows and the two-line fix that stops it.
