CSS customisation

Hi, great plugin, and I installed the customiser as well. I have a problem with the layout of things. For some reason my password field appears at the top of the page instead of being entered vertically.

I then went and inspected the code and with some modifications I have found that this code would centre the form vertically:

#login {

position: absolute!important;
top: 50%!important;
left: 50%!important;
transform: translate(-50%,-50%)!important;

}

unfortunately if I add this code in the CSS customisation under appearance, or even if I add it to the theme settings in Elementor, nothing happens on the front-end, and the form still appears at the top of the page.

Where can I insert the custom CSS to modify the standard behavior of the form?

thanks
