Editing problems – things keep moving

Hi,
I am having a complete nightmare trying to set up a website with wordpress. I can see that most people here are using code, but I am trying to edit using visual – as I have no coding skills. Every time I go to edit a page, or add an image, the whole thing has moved, weird line breaks, and the images won’t stay still. I set the image and text, hit publish and …bam..everything has moved place. Can anybody help me? Please…
Thanks
