I want to remove the red zone and centre the module in the page

Best regards

Please go to Extensions -> Modules and turn off Login Left module.

Use this CSS to Template Options -> Custom Code -> Custom CSS

@media only screen and (max-width: 2560px) {
  .view-login #sp-component, .view-registration #sp-component{
    position: relative;
    left: 30%;
  }
}
@media only screen and (max-width: 1440px) {
  .view-login #sp-component, .view-registration #sp-component{
    position: relative;
    left: 20%;
  }
}
@media only screen and (max-width: 425px) {
  .view-login #sp-component, .view-registration #sp-component{
    position: absolute;
    left: 0%;
  }
}
