The next step is to put images between the text blocks.
The first step is to select the Rectangle Tool and draw our a box that stretches from one side of the page to the other. With the rectangle selected, I set its height to 250 pixels and its Y position to 425 pixels. The plan is to have them always stretch or contract to the page width to accommodate a user’s browser viewport. To accomplish this I clicked the 100% width button in the Properties.
What this does is to grey out the X value and to ensure the image is always 100% of the viewport width in a browser.
