How do I change only part of a webpage?
I'm just starting out as a web designer and I need help figuring something out.
The Main Content part of my web page has a white box with text and a picture on the left side, and a sidebar of links on the right side. My teacher is currently telling me to make each link on the right go to a completely new webpage that has just the content in the white box on the left changed.
Is there a way to make this all part of one webpage file? Where the links on the right only changed the content in the white box on the left and they didn't have to be linked to completely different web pages?
