What is the double border problem this solves?
When two adjacent elements each have a 1px border, the shared edge shows a 2px border. This tool generates CSS so the shared edge shows only 1px.
Is this specifically for Webflow?
It's primarily designed for Webflow users but the CSS works in any web project.
Does it support grid and flexbox layouts?
Yes — the generated CSS handles both column and row adjacent borders.
Do I need to understand CSS to use this?
