Orange bar growing when page is shrunk

MyCuisine Restaurant is a commercial theme from Elegant Themes. Please post your question on their support area.

These forums only deal with issues concerning the free themes from the WordPress Theme Directory.
Forum volunteers are not given access to commercial products, so they would not know why your /custom/commercial theme or plugin is not working properly. The developers/vendors are responsible for supporting their custom/commercial product.

I would have asked them for help, but this is the last update of My Cuisine before my account expired, and therefore a loss of technical support. I was hoping the issue was an easy fix, but if not then I guess I’m out of luck.

I cannot reproduce your problem. I went all the way down to 320px wide on (Windows) Firefox, Chrome, I.E. and Opera and no orange bar appeared.
I will say that there is something seriously wrong with your theme as it is not responsive nor is anything lined up properly.
You need to contact the theme’s support.
The Forum cannot help you because no one can get access to the theme’s structure code.

If you try shrinking the window on a page besides the home page the problem occurs, I didn’t realize that when I posted. Is the problem deeper than a css issue? Because you can see that information in the inspect option right?

Oh, and the bar is actually tan.
