Adapting to dynamic content using modern CSS

A walkthrough of using modern CSS features to adapt UI components to dynamic JavaScript-driven content. Demonstrates using the CSS `attr()` function to read HTML data attributes (weather type and precipitation amount) as typed values, then applying CSS style queries to conditionally display different weather icons based on those values. Shows how to handle multiple conditions, including combining weather type and precipitation thresholds to show heavy rain, light rain, or partly-cloudy-with-rain icons without hardcoding values in JavaScript.
