Animated Weather Card in Vanilla JS

tags and semantic HTML to ensure proper rendering.

Basic HTML Layout

Apply CSS Styling

With the HTML structure in place, we now turn our attention to styling. CSS will define the visual appearance of our weather card, including colors, fonts, and layout.

Overall Card Appearance

This part is about the general styling to make it visually appealing.

Implement JavaScript Logic

The JavaScript code adds interactivity and animation to the weather card. It dynamically updates the card based on the selected weather condition.

Core JavaScript Functionality

Implement logic here for animation, weather updates, and overall functionality.
