/* 使用自定义属性和calc()计算列宽 */
grid-template-columns: calc((424px / (100% - var(--offset))) * 100%) calc((608px / (100% - var(--offset))) * 100%);
In a grid, I have two items, one is 424px and the other is 608px. I want them to be responsive. But padding and gaps can cause visual errors. So I want a percentage with calculation:
Logic: ((424px / (full width of div - 30px)) * 100%) so that our divs will always resize their width
please help me. Here's a problem reported by the CSS validator: "An operand must be a number"
I have been doing this for 4 hours: {

Based on the values you use, this seems to be the right thing to do. It's responsive and basically the same size with a 30px gap between them. I think your solution is too complex and fragile, especially on the responsive side.
Your number:
This is roughly a ratio of 40% to 60%. Using
4fr 6fror better yet2fr 3frshould be close enough..grid { display: grid; grid-template-columns: 2fr 3fr; gap: 30px; height: 300px; } .col { background: lightseagreen; }If you prefer, we can get closer by using
424fr 608fr. This is an odd number, but it will be the exact value you are looking for. Of the total width, use 424 scores for the first column and 608 scores for the second column. Then add intervals..grid { display: grid; grid-template-columns: 424fr 608fr; gap: 30px; height: 300px; } .col { background: lightseagreen; }
