In this episode, we’re addressing a common issue with making our grid responsive, especially right after a page load. First, we recap how we grab the width of the container—using a bounding box—and how we use that to divide up our grid items evenly across the available space.
However, as shown in the video, there's a little glitch: when you resize the viewport and refresh the page, sometimes items overlap or don’t lay out correctly. This is because the initial calculation for the grid items’ widths is only happening after a certain event (like resizing), not immediately on load.
To fix this, we update our approach so that the layout calculation happens right away when the page loads, as well as when the window resizes. The quick fix is simply invoking our onResize handler as soon as the page loads, ensuring the grid always uses the correct container size whether the page is loaded or resized. Now, no matter what the viewport size is—on page load or after a resize—the items fit perfectly!
You can continue to tune the grid’s responsive behavior if needed, but this tip helps nail that initial page load issue.
