{"version":"1.0","type":"rich","title":"Synopsis","description":"This example shows a DOM element’s CSS style properties being monitored for changes, logging each modification with its old and new values. It demonstrates both a single-property listener and a multi-property change handler. The code uses Backbone.Events for event handling, MutationObserver to detect style attribute mutations, and Underscore for utility functions. The demo binds to `transform-origin` and `border-radius` on a div, then programmatically updates `transform-origin` after one second, triggering the change callbacks.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-c3b9584d63bfd802e08f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
