## What it is
A classic Alibaba library that adapts web page layout to different screen widths by dynamically setting the root font-size (rem-based scaling) for mobile web pages. It is now considered a transitional solution, with the README recommending native viewport units instead.

## Use cases
- make a mobile web page scale across different screen sizes
- rem-based responsive layout for legacy mobile H5 pages
- adapt page layout to device width automatically
- maintain an old project that still uses lib-flexible

## When to choose
- maintaining a legacy mobile web project already built around rem scaling
- targeting very old browsers that lack viewport unit support

## When to avoid
- starting a new project - use CSS viewport units (vw/vh) instead
- the README itself recommends abandoning this library in favor of viewport units
