Examples
Basic usage
Once support is implemented for this property, it will probably work like so:
When you've got a container with some inline children and you want to put a margin between each child but not have it interfere with the spacing at the end of the row, you might do something like this:
article { background-color: red; margin: 20px; padding: 20px; display: inline-block; } article > span { background-color: black; color: white; text-align: center; padding: 10px; margin-right: 20px; }
The problem here is that you'd end up with 20px too much spacing at the right of the row, so you'd maybe do this to fix it:
span:last-child { margin-right: 0; }
It is a pain having to write another rule to achieve this, and it is also not very flexible. Instead, margin-trim
could fix it:
article { margin-trim: in-flow; ... }
