WordPress site is too close to the screen

It’s not clear to me what you really want to do. I think you want your site’s content area to be wider on larger screens. It looks like a lot of content width is managed by this CSS rule:

.gridContainer {
    max-width: 1232px;
}

Try adding this to the bottom of the Additional CSS panel of the customizer, using a number larger than 1232.

I have to show you a demo for you to understand.
https://extendthemes.com/mesmerize/demos/demo8/

this is demo. this exact pattern and distance is good. but our site stands too close.

Your site and the demo both appear to be similar in appearance. I don’t understand your meaning when you say your site “stands too close”. Do you mean the zoom level (overall scale) is wrong? Zoom level is managed locally in your browser. When a page is zoomed by the browser, there should be a tool icon right of the address to manage zoom level. On many computers, pressing Ctrl-0 (control key + zero key) restores 100%, normal zoom. There’s no tool icon visible when at 100%.

yes I know . but the articles, logos, pictures on the site all seem close to the demo. I want them to be full screen and remote like demo. So I want to integrate the image that I did ctrl – 90% in the browser to the site. And I want it to remain constant. because that’s how it is in this demo. and wordpress org is also remote and full screen.

I’m sorry, I still don’t understand what your goal is here. Both your site and the demo appear to behave and scale in the exact same ways. I don’t see what is lacking on your site that you want which is represented by the demo. What is full screen or how remote is managed by your browser controls, not the site. The site does manage its appearance at full screen, but but whether it is full screen or not is determined by your browser.

Maybe if you made a screenshot of both your site and the demo site so I can understand what you are seeing. You can use snipboard.io or any other similar image sharing site. Then just provide the links to the images here.

the same browser but the demo looks thin and the other far away is rough and close to the screen.
I could not solve this incident. both are something done with WordPress
