Recap Challenge

Part of the Practical Frontend section of Coddy's HTML journey — lesson 25 of 35.

Challenge

Easy

You are given an HTML page with different UI components (dropdown menu, tabs, badge, tooltip, and a notification banner).
Your task is to complete the CSS so that everything looks and works properly.

Your task:

Style the notification banner with a green background (rgb(76, 175, 80)) and white text.
Position the badge in the top-right corner of the message icon (use position: absolute, top, and right).
Hide the dropdown menu by default.
Hide the radio inputs used for the tabs.
Style the tooltip with a background color, rounded corners, and padding.

The final result should look like the picture below.
