Dynamic Weather Themes & Icons

This module connects live weather data to the prepared visual system. No new visual design is required: the CSS already defines the clear, clouds, rain, storm, snow, and night states and contains the rain, snow, and star effect layers.

You will build the JavaScript mapping from OpenWeatherMap condition IDs and icon codes to those CSS classes and Font Awesome icons. The same helper will be reused for the current card and forecast cards.

By the end: weather data changes the application’s atmosphere and iconography without changing the page structure.

Start here: complete the implementation lessons in order. Each lesson assumes the checkpoint from the previous lesson is working.
