The page is beautifully done.
I found a small problem, when the code is presented, writing a line of code will be empty.

Click to copy and you will find that essentially the blank line in the middle does not appear.
This is actually a distinction made when a single line of long code cannot be represented by a single line.

At present, let's mainly focus on the issues in the functional process and see if there are any major flaws in the functional process. Let's improve the style through continuous iterations in the future. Let's push things forward first.

I don't think there's a problem with the function!
