Mobile worked before, now not?

Hi, Please see: - if I go to a mobile emulator like on Firefox, I see a blank page (I see this with all the pages I have tested on that site. Also, if I use the Firefox website developer extension, and look at responsive layouts, I see a blank page. When I go to Chrome and use, it looks ok. It also looks ok in Chrome developer tools.

So, question one- does it look ok on your mobile, or do you get a blank page?

Question 2- if a blank page, then it must be something changed in the js/apps.js, as nothing else has changed. Can anyone help me figure out what is in apps.js that causes the blank page?

Thanks very much.

Yup, it's a big yellow page. And empty.

I would suspect one of your multiple @media queries. I would bet one is unpremeditatedly switching some blocks display to none...
Seems that the switch happens between a width of 800px (no problem) and 600px (problem).

Thanks. Another expert rewrote the app.js to fix another issue. Maybe I need to go back to my old app.js and work on fixing that issue another way.

No, that was not the problem. So I have had work done and changes made the last week on:

bootstrap.css, style.css, and app.js. Nothing else has been changed in the css and js files.

I have replaced each of those files with the original, but I still see the problem. I guess I will do it again while testing to be sure the new file has loaded. An other ideas? Thanks.

OK, I did that, and the problem appears to be in the changes he made to bootstrap.css. Darn, I had worried about that, I had heard never to change bootstrap.css.

I'll go back to the person who made the changes. Meanwhile, if anyone here can help to find the issue on the attached css, I would be deeply appreciative!
