Guest Portal CSS

Hi all

I want to style the splash-page for the guest-access-portal.
Since we’re mostly using mobile devices or smartphones, the default layouts do not cover, or proper support, portrait mode.
I want to create the splash page like this:
“LOGO” incl. background-color
“FOOTER” incl. short description, T&C-link and login-button

I’ve tried with custom CSS, but the provided sample.css does not cover all elements of the page, and some CSS-rules like flexbox are ignored.
How can one create a nice splash-page? :slightly_smiling_face:

Thanks and best regards,

I stand corrected, flexbox works, but there are just too many classes that are not editable using CSS… I’d really appreciate if someone of Cambium could help out here…
