I have a problem with Bootstrap CSS and I can’t figure out how to handle it…
I have decided to start my design from the scratch in CMSMS 2 but also with implementation of Bootstrap and certain parts of Universal theme. I’m working on Mac and Safari and on my configuration everything is exactly as it should be (see img1.jpg). But when I go to Chrome, Firefox or IE, on Mac or PC, it seems like certain parts of my CSS has been overridden for some reason.
In img2.jpg you can see what happens with vertical tabs and its contents and in img3.jpg you can see the mess in yellow “logo-scroller”… Tabs and scroller are fine in Safari as captured in img1.jpg.
If I use developer tools I can see it’s a matter of loading or not loading proper CSS. Even if I use !important on some properties it doesn’t matter - like I have never customised it.
As far as I can understand this issue, Chrome, Firefox and IE are disregarding my CSS for a reason unknown to me. Any ideas from fellow CMSMS users? If you need the code just say it because I’m not even sure which part of code to paste here…

Thank you in advance and best regards!
