I have an idea. I'm not sure if it's correct. I hope everyone can judge it.

I hope to downgrade the useWindowDimensions hooks to a regular function. Using a listener to modify height, width, and scale is a poor practice. By adopting the rem scheme, height and width can be set as unchanging strings (e.g., height: '1rem'), which not only meets adaptability needs but also enhances performance. Specifically, set the font-size of the html node to 40px, so 1rem equals 40px. When the screen size decreases, adjust the html node's font-size to 20px, making 1rem equal to 20px.
