The title in the head is displayed in the body, and the headtitle is displayed in the body.

One problem today is that the content in the title will be displayed in the body.

I searched the internet to find out that this problem may occur when there is a problem with the encoding method. So I checked my encoding and found that there was no problem. So I started troubleshooting and removed the css style sheet. The title will not be displayed. It seems that there is a problem with the style.
 
After troubleshooting, we found that the previously written reset style is as follows.
 
1 * {display: block ;}
 
 
 
Then it seems that the default browser is display: none. Because the title is also a label, it is effective for css, so the display: block is removed and displayed normally.
