jquery resizer

The tool models dynamic resizing of DOM elements when their container changes size. It accepts selectors for the container and the target element and uses a baseline width to compute proportions. It is designed for developers building responsive widgets, dashboards, and components that must scale consistently.
Conceptually, the tool calculates a scale factor from container width relative to a baseline. It supports aspect_ratio to preserve shape, min/max constraints to prevent overflow, and modes such as fit, fill, and stretch. It does not modify the page directly; it outputs numeric dimensions and CSS fragments for integration.
The output is a set of computed width and height values, an optional CSS snippet, and a suggested ratio to guide styling decisions. It benefits frontend engineers seeking predictable layouts across devices and design systems that require documented resize rules. Core features include selectors-based targeting, optional aspect ratio handling, clamping, and a resize observation loop with a graceful fallback if modern APIs are unavailable.
The approach is deterministic, testable, and packaging-friendly, enabling integration into build scripts, design-system tooling, or runtime helpers that apply calculated styles.
