Need help with site Header Strip <Needs Solving>

I have written down code for my sites header but for some reason, when I view it in preview mode everything is fine but then on the live site it is shown as clear. I am trying to figure out why it is doing this. I have provided a video here .

What is happening:
In my video, I first show how the website headerStrip1 is not really working on my live site. I have checked all of the cache and troubleshooting. I want to know why all of my strips are moving up without staying on the page. When I show the preview from my site, the strip works well. So I am trying to find out what is wrong with the Strip itself. Please help.
