I've noticed on my site that the responsive navigation menu I created in Menu Builder and display in RSD (via the HTML element feature) is a little bit jerky on the mobile view when the user clicks on the hamburger symbol to open and close the menu. I noticed this behaviour when I tried the navigation on its own without any other file interferring. I have just discovered that this problem is being caused by the 'wireframe-theme.min.css' file. When I delete this file from the head section, the problem stops. So what part of this file is interfering with my menu bar?

Has anyone else had this problem?
