Is it possible to do this for a long time?

What do you mean by 100px by 100px is sprinkled with variables?

If you want to fill the background with a repetition of a specific image according to the screen size, CSS's background You can use properties.

body {
    background-image: url("paper.gif");
    background-repeat: repeat;
}

Go to the link below and change repeat-y to repeat and press the run button. http://www.w3schools.com/cssref/tryit.asp?filename=trycss_background-repeaty

It's possible.

However, I think this is something that needs to be solved at the front end rather than Django. Depending on the size of the browser, it is desirable to request a specific number, or to resolve it at the front and end so that only a specific number is visible.
