css - When you open a few websites such as github and bilibili on mobile phone chrome, you will find that there will also be a background color around the address bar.

Question

I accidentally noticed that several websites have such full-screen background colors. How do I set them up? I looked at the head and there are no settings, but it is not the set body color. Has anyone seen it?

Answer 1
