Flex Luthor, a Little CSS Flexbox Layout Helper

February 25, 2023

Just going through the backlog of some old projects and found this Filament Group gem that went unpublished!

Flex Luthor is a small CSS wrapper library to help with responsive intrinsic-sized Flexbox layouts that wrap based on content and container width (avoiding viewport-based media queries).

View the Demo or Source Code

This library predated Flexbox support for the gap property but I updated it to use gap in the new v3.0.0 version. I think the coolest feature it provides is the addition of borders only when cells wrap to a new line (horizontal, vertical, or both).


Available on npm

npm install @zachleat/flex-luthor --save
