The anyee application on Microsoft Edge is a multitasking application with three main functions:

Search product
Users can enter search keywords in the "Search Keyword" box and press the "Search" button to search for products on the anyee.com website.
The search results will open in a new tab.

Calculate BMI (Body Mass Index)
Users can enter their weight and height in the corresponding boxes.
They can then press the "Calculate BMI" button to calculate the BMI and display an alert window with the results.

Calculate the product price of anyee's t-shirts
Users can select products from the list in the "Products" box and enter the desired quantity in the "Number" box.
They can then press the "Calculator" button to calculate the price and display the results, including price, promotional price, style, color, size and detailed product description.
Each result will be displayed in a green notification box with a close button in the top right corner to close the notification.

The app has a user-friendly interface, uses Bootstrap to create responsive layouts and visual effects, and uses jQuery to handle events and communicate with HTML elements.
