How to cancel the gap between the div definition block and the right side of the screen, please guide me_html/css_WEB-ITnose

In the web page I made, I feel that there is a gap between the overall frame and the browser. How to solve this and what causes it? I just studied it by myself. I hope the master can make it easier to understand. Thank you.

Look at the css of various websites on the Internet. There will be one or a section of css specially used for reset. Set it in a targeted way
It is not recommended to use *{margin: when pursuing performance. 0;padding:0;},

body { margin:0; padding:0; }
p,h1,h2,h3,h4,h5,h6,ul,ol,li,dl, dt,dd { margin:0; padding:0; }

Write this sentence globally *{margin:0;padding:0;}www.seo7ye.com
