Need some help with layout and css

Hi,
I've given you access to the the site.

I'm setting up a template for my pop-ups and have run into some trouble. I've finally faced the fact that I need to know coding to move on but I'm a total novice so I'm probably doing domething wrong. I created the code in a separate editor and pasted it into the word press editor. The layout looks okay in the WP visual editor but doesn't show properly in the pop-up itself. I've also added some CSS. The same code looks okay when I view it from the editor I'm using. Still not exactly the way I'd like it to be. Attached images for reference:
1. The WP visual editor version.
2. The Pop-up preview.
3. The code as it previews in the separate editor. I could live with that if I could figure out how to get the text to wrap the photo.
4. The way I'd really like it to look.

Any help you could give is greatly appreciated.

Thanks!
Terry
