Hi crowd,
in c5.6 it was easy to add css and / or html code from either the block design menu,
or from the page properties custom attributes menu - in header extra content you could add code or scripts.

I can't find this in c5.8 ... is it still possible or not?
Reason is I have access to the site but not to the files or server, so I can't make changes to php or ccs files, I can only make changes from within the admin area.

Any help there?
thxs, your time much appreciated as always
