hi! if it's breaking the entire code, chances are you're matching your opening and closing tags incorrectly (e.g. you have an extra </div> or one of your <div>s doesn't have a </div>). if you have the code editor turned on, you can place your cursor in one tag, and its matching closing/opening tag will be highlighted with a little border around it, so you can check if it's all lined up correctly.

if you want to put text in the place of the image, all you need to do is remove the "focal image" section and copy/paste the "main text" section in its place. custom colors are added with color: #000000; for the text color and background: #000000; for the background color (replace #000000 with the color you want) in the style="" attribute.
