Hi
I like the website layout in the responsive example using css3
Collapsible Responsive Side Navigation
https://www.w3schools.com/w3css/tryit.asp?filename=tryw3css_sidebar_hide&stacked=h
However, when downloaded the example to my computer and when replacing the "#" in Link with a real filename and when clicking on the link, it opens the link in a new window/screen and hides the initial screen. Seem to have the same problem with the other examples. I got around this problem using <iframe> but this is messy and confusing as it gives two scrollbars. What am I missing?
