This boostrap css code about background image.

background-image: url("data:image/svg xml,");

And I tried to rename img file to another but It didn't work. Either when I try to add image in index.html and name was bg.jpg it didn't change the img that I paste the file.

Supposing that your actual CSS configurations are correct and you still can't see your changes live, the reason could be that sometimes browsers do cache the CSS, so this is the reason that you may not see your changes.

You need to clean the cache - try to do that on going to history -> clear cache

or by pressing ctrl F5

Here is a guide to clear cache on chrome
