CSS Grid Not Aligning Items Correctly in Firefox but Works in Chrome

I'm following best practices but I'm working on a project and hit a roadblock. I'm working on a personal project and I'm experiencing a frustrating issue where my CSS Grid layout behaves differently in Firefox compared to Chrome... In Chrome, my grid items align perfectly in a 3-column layout, but in Firefox, they seem to shift unexpectedly, creating extra spaces between some items. I have a simple HTML structure like this: ```html <div class="grid-container"> <div class="grid-item">1</div> <div class="grid-item">2</div> <div class="grid-item">3</div> <div class="grid-item">4</div> <div class="grid-item">5</div> <div class="grid-item">6</div> </div> ``` And my CSS is as follows: ```css .grid-container { display: grid; grid-template-columns: repeat(3, 1fr); gap: 10px; } .grid-item { background-color: #ccc; padding: 20px; text-align: center; } ``` In Chrome, this renders as expected, with all items neatly aligned in three columns. However, in Firefox, the third column has an odd alignment, and I often end up with an excess margin on the right side. I've checked for vendor prefixes, but I still don't see any improvement. I tried adding `box-sizing: border-box;` to my grid items, but that didn't help either. I also inspected the items using the developer tools and noticed that Firefox applies different default styles for margin, padding, or even box model calculations. I attempted to explicitly set `margin: 0;` and `padding: 0;` for my grid items but still faced the same issue. This inconsistency is making it difficult to maintain a uniform design across browsers. Is there any known workaround or specific property I should be aware of that can cause such discrepancies? Any guidance on this would be greatly appreciated! My development environment is Ubuntu. Any help would be greatly appreciated! My development environment is Windows. Is there a better approach?
