The reason why css files are placed in the header is that css files are placed in the header

This question I posted on Blog

Then someone will reply to me like this.

I think it makes sense.

So I put it on.

 

In this way, the css style will be loaded first, and the style will be known when the dom is rendered, so the rendering is successful once.

If the css is placed at the bottom, you need to render the dom first, then load the css, and then re-render the dom. Two renders are required.
