CSS Grid Not Respecting Minmax Settings with Nested Grids in React

I'm stuck on something that should probably be simple. I'm currently working on a responsive layout using CSS Grid in a React application, specifically React 17... I've set up a grid container with a nested grid inside one of the grid items. However, I'm working with an scenario where the nested grid items are not behaving as expected when applying `minmax()` in the parent grid. Here's a simplified version of my CSS: ```css .parent-grid { display: grid; grid-template-columns: repeat(3, minmax(150px, 1fr)); gap: 20px; } .child-grid { display: grid; grid-template-columns: repeat(2, minmax(100px, 1fr)); gap: 10px; } ``` And in my React component, I have something like this: ```jsx return ( <div className="parent-grid"> <div className="child-grid"> <div>Item 1</div> <div>Item 2</div> <div>Item 3</div> <div>Item 4</div> </div> <div>Other Item</div> <div>Another Item</div> </div> ); ``` The question arises when the viewport shrinks. The child grid items aren't adhering to the minmax settings defined in the parent grid. Instead, they overflow their container and don't wrap as expected. I've tried adjusting the grid template columns in both the parent and the child grids, and also applied `overflow: hidden;` to the parent container, but nothing seems to resolve the scenario. I'm seeing this behavior consistently in Chrome and Firefox but not in Safari. I've checked for CSS properties like `box-sizing` and ensured that no conflicting styles are being inherited from global styles. Could anyone provide insights on why the child grid isn't respecting the minmax settings, or suggest other approaches that could help achieve the desired responsive layout? Am I missing something obvious? For context: I'm using Javascript on Windows.
