Sorry all, I know this gets asked a lot. And I wouldn't ask again - except that the old threads on this topic don't seem to align with the latest code base (change the "claim widget"? - I don't see that).
I understand that you can export your portal page from the Captive Portal Editor, extract the files, edit the gui.data file, re-zip, import the file and save. But nothing I change in gui.data seems to make a difference.
All I want is for the overall page width to be MUCH narrower. At least that is what I think will fix it. Also, I cannot believe that in this day and age there is not a checkbox or some other feature that says "make this mobile friendly". It's 2017 gentlemen - and %90+ percent of my guest wireless traffic is on mobile devices with narrow displays. Can we get a feature request going please?
Image related, it's a "guest sign in page for ants". LOL
