How to make my background image full screen?-CodePudding

I'm doing a project in python django and trying to make my background full screen.

The html code:

CodePudding user response：

Css for container-login100 is correct, maybe there is something wrong in the parent container. For example you can have margin, padding, or other instruction that prevents the container-login100 to expand itself and grow to cover all the free space. Maybe is better if you post parent code and style
