Mobile-first Bootstrap Template in Joomla needs your help

Thank you for reviewing my project. I am hiring immediately to help me solve my problem. I need a "fresh set of eyes" on the desktop css/html that is not pulling in the css styles. Test Location: [login to view URL] If you look at all devices, the header does not look good. I am not worried about that. It is still in progress. Here are the issues I am facing: 1) The phone view shows correct .css styling for: a) Home Page > the slide tagline, :Bring The Thrill and Excitement of Horse Racing To Your Next Event!: (a css rule located in the Layer Slider Component) is supposed to be centered with a purple background and white text b) Home Page > "Horse Racing Kit Includes": yellow background styling c) Home Page > The blue background that is 100% wide behind Horse Racing Kit Includes: and the gallery categories. This is the background layer for module positions "highlight-a" and "hightlight-b" as seen at [login to view URL] d) The format of the products at [login to view URL] 2) The desktop view does not pull these styles. It ignores them. From what I see, the html code generated does acknowledge the module suffixes that I added. So, the problem is in the template. I am not sure if it is in [login to view URL] or the main css file called "[login to view URL]". Also, since it is a mobile-first bootstrap framework, I wonder if my problem is the [login to view URL] file. As soon as I started changing [login to view URL] to be mobile-first, the desktop view broke. For this project, you will need to have a full understanding of bootstrap, Joomla templates, css and @media queries for responsive design. If I hire you, I need you to be able to work while I sleep tonight. This is an unusual request since I usually have projects with realistic deadlines. Again, I appreciate your time and know that I am asking for a fast turnaround. I am attaching the 3 main files that contain the problem so you can decide if it is worth your time. I am also attaching [login to view URL] since it is easier to read. Thank you, Mary
