A JavaScript polyfill enabling cross-browser support for the 2009 CSS3 Flexible Box Model specification.
Flexie is a JavaScript polyfill that enables cross-browser support for the 2009 CSS3 Flexible Box Model specification. It allows developers to use flexbox layouts in older browsers like Internet Explorer 6-9 and Opera 10.0+ by parsing CSS and applying the necessary properties programmatically. The tool normalizes inconsistencies between browser implementations and provides an asynchronous API for dynamic flexbox manipulation.
Frontend developers and web designers who need to implement flexbox layouts in legacy browsers, particularly those supporting Internet Explorer 6-9 or Opera 10.0+.
Flexie provides a straightforward solution for using flexbox in browsers that don't natively support it, without requiring complex workarounds. Its integration with Selectivizr and programmatic API offer flexibility for both static and dynamic layouts.

Enables flexbox layouts in Internet Explorer 6-9 and Opera 10.0+, where native support is absent, as confirmed by the browser support list in the README.
Implements all key properties from the 2009 spec, including box-orient, box-align, box-direction, box-pack, box-flex, box-flex-group, and box-ordinal-group, allowing full use of the old flexbox model.
Attempts to normalize inconsistencies between Webkit and Gecko browsers, such as default values for box-align and box-pack, ensuring more uniform behavior across supported browsers.
Provides an asynchronous API for programmatically creating, updating, retrieving, and destroying flexbox instances, useful for interactive or dynamically changing layouts.
Only supports the deprecated 2009 CSS3 Flexible Box Model, not the current W3C standard, limiting its relevance for modern web development as noted in the README warning.
Incompatible with YUI selector engine due to its use of dashed attributes, as highlighted in the caveats, which restricts usage in YUI-based projects without workarounds.
Modifies the DOM to mimic flexbox, which can break CSS rules that use pseudo-selectors like :first-child, especially with properties like box-direction: reverse, as admitted in the caveats.
