Help! Custom css not working anymore on the PC version :(

Hello!

I made some modifications to your plugin, always applying solutions already discussed in these forums. I added the special plugin for making the phone mandatory, and it works perfectly. However, there are some changes I made which were working perfectly for both mobile and pc browsers, and are not working anymore on the PC browsers.

-I changed the font for the reservations form, followint these indications: https://www.ads-software.com/support/topic/custom-font-for-the-booking-form?replies=3
It worked great, and the mobile version shows it perfectly.

-I changed the button style following these indications:

And again, it worked perfectly on both PC and mobile versions, until all of a sudden it stopped working. It is showing perfectly on the mobile version, though.

-I forced the message field to appear always, as instructed here: https://www.ads-software.com/support/topic/allways-show-message?replies=3
It is showing perfectly on the mobile version, but not anymore on the PC version.

(I did not install any new plugins, so I don’t think there is anything interfering with the code). I have cleared the cache multiple times and tried different browsers, but no PC browser will show the style I wanted, even if it works perfectly on the mobile version.

Could I please get some help with this? I am so sad it stopped working, I was so happy with the results ??
