this is my first message! I can't find answer on my question on the webpage. I'm going to do responsive website but I have a problem with mobile navigation on the phone. The navi links overlaps h1 and links dont's react (does not work as it should). The z-index not helps here and the backgorund-color on mobile-navi looks bad and links still don't react. Give me an answer if you have some idea to fix it. My webpage: http://jakub-lawniczak.com/
set z-index
to .main-nav
This will fix your overlaping issue
.main-nav {
position:relative;
z-index:9;
}
