— what it is

In Figma, when you place two adjacent panels with a 1px centre stroke, the shared edge shows a single clean 1px border. In CSS, if both elements have a 1px border, that shared edge shows 2px — a subtle but visually wrong result that undermines the precision of the original design. The Shared Border CSS Generator produces the exact CSS needed to replicate Figma's behaviour in a browser, particularly in Webflow layouts.

Developers and designers who care about pixel-perfect design-to-code fidelity, particularly those working in Webflow or any CSS grid layout where adjacent bordered containers share an edge, will find this tool saves a surprising amount of time on a problem that's easy to get wrong.
