The title in the head is displayed in the body

I encountered a problem today, that is, the content in the title will be displayed in the body

 
 <title>324234</title>
 

After searching online, it said that there is a problem with the encoding method. In this case, I checked my coding and found that there were no problems. So I started to investigate, and after removing the css style sheet, the title was no longer displayed. It seems there is something wrong with the style.

After investigation, I found that the previously written reset style is as follows.

 * { display: block; }

Then it seems that the browser default is display:none. Because title is also a label, it takes effect on css, so if you remove the display:block, it will display normally.
