QUESTION:
Hello! I want to build website for my own purpose. I don’t know much of html or other programming languages, so I decided to make the website in Dreamweaver. I’ve learned that there is a mouse-over function in the program but I don’t know how to use it. After I import the image in the document, I right-click it looking for the “image swap behaviour” function but I can’t find it. Please, help me! I’m just a beginner! And please, I don’t want html coding! Thank you in advance!
