A JavaScript polyfill that enables Flexbox layout support in older browsers like IE8-10.
Flexibility is a JavaScript polyfill that implements the CSS Flexbox specification in browsers lacking native support, such as Internet Explorer 8–10. It parses and applies Flexbox styles dynamically, allowing developers to build flexible layouts without breaking older browser compatibility. The project serves as a bridge to adopt modern CSS while maintaining backward compatibility.
Frontend developers and teams who need to support legacy browsers (especially IE8-10) but want to use modern Flexbox layouts in their CSS. It's also useful for projects with strict cross-browser requirements.
Developers choose Flexibility because it's a focused, lightweight polyfill that solves Flexbox compatibility in a straightforward way without requiring major workflow changes. Its API allows integration into custom build processes or frameworks, offering control over polyfilling behavior.

Implements Flexbox in browsers like IE8-10, enabling consistent layouts where native support is absent, as highlighted in the README's cross-browser focus.
Requires only including a script and calling a method on DOM elements, making it easy to add to existing projects without major changes.
Provides read, write, readAll, and writeAll functions that work with any JavaScript framework, offering flexibility for custom integrations.
Supports -js-display: flex or data-style attributes to selectively apply polyfilling, useful for conditional browser targeting without disrupting modern CSS.
Developers must add non-standard CSS properties or HTML attributes for the polyfill to work, increasing maintenance and risk of errors in styling.
Layout correctness relies on JavaScript execution, which can fail if JS is disabled or cause flash of unstyled content (FOUC) during loading.
Only polyfills Flexbox, not other CSS features, and as browser support evolves, the project may see less active updates or miss edge cases in newer specs.
