This week will be simple in concept. You need to find your own images and create your own layout. You are going to focus on using the iFrame.
But this is also going to introduce a small slice of JavaScript that will instruct the browser what to do when the mouse rolls over one of the images and back off it again. Watch the video and then do the same thing but exercise better image control with CSS3.
Be aware that iFrames work in all browsers and are constructed the same no matter which tool is used. The APDiv technique only works with Dreamweaver. The big advantage is that DW allows you to drag and drop your iFrame instead of having to figure out the positioning coordinates.
Below is an example of an embed code from YouTube. This is how you add a YouTube video to your site. Notice the use of an iFrame to accomplish this.
