This site has a header on the homepage, set to be sticky. The problem is that the bars don’t stay in one place; they wander about vertically when scrolling. Also they stop the page scrolling smoothly, scrolling needs two or more attempts to scroll down.
This behaviour stops if I remove the footer from the site.
Will you please have a look and see if you can find a reason for this?
