Research & Planning - InDesign Tutorial

In this tutorial of InDesign, I have learnt how to make columns, add pictures, add a background colour and add text on to InDesign. When I did this I copied and pasted a text before I used the text on to the InDesign page. When I pasted my text in my first column it carried the text on in the next column. Once I added the text I next added a title and then placed an image on the piece. Afterwards I then changed the background and it came up on the top of my text, i right clicked and sent the background to the back.
