Unexpected Margin Collapse in Nested Flexbox Containers - guide Needed
I'm refactoring my project and Quick question that's been bugging me - I'm working with an scenario with margin collapse when using nested flexbox containers. I'm attempting to create a layout where I have a parent flex container with several child elements, each of which is also a flex container. However, I'm noticing that the margins of the child flex containers are collapsing with the margins of their parent, resulting in unexpected spacing in my layout. Here’s a simplified example of my CSS: ```css .parent { display: flex; flex-direction: column; margin: 20px; } .child { display: flex; margin: 10px 0; background-color: lightgray; } .item { flex: 1; padding: 20px; background-color: white; } ``` In this setup, I expect each `child` to have a 10px gap from each other, but instead, they seem to be collapsing into each other, leading to a total gap of only 10px instead of the expected 20px. I've tried adding a `padding` or a `border` to the `.child` class, but that didn't resolve the scenario. I also verified that I'm using Chrome version 117.0.5938.92, and the scenario continues across multiple browsers. I've read that margin collapsing can occur in certain conditions, but I’m not sure why it’s happening here. Can someone explain how I can prevent this margin collapse or if there's a better approach to achieve the desired spacing? Any insights would be greatly appreciated! I'd really appreciate any guidance on this. Could someone point me to the right documentation?
