Hello,
I am an amateur beginner just trying to get an informational site together but, for some reason, I must have changed something because the links in the horizontal menubar jump when you click on them. All other links are fine. This was never to be the case. I cannot find out what changed and set this general post as I don't know if it is in the html, css or js.
the site is: http://www.environmentalhistory.info/
I hope it is an embarrassingly simple mistake with a simple solution.
Thanks for your help.
