can't change background-size to "contain"

Hello jamesl2015,
Send a screenshot about where actually you want the modifications.
Also share the site URL.
Thanks.

The URL is :

https://programs.wellocitywellness.com/employer-login

The background-size is set to
background-size: cover;

I want to set this to
background-size: contain;

The only other option the plugin provides is
background-size: auto; when the stretch checkbox is not marked

Thanks
James

Hello jamesl2015,
add the following section of code in custom css-
html body.login {
background-size: contain !important;
}
thanks.
