I am using the blocks theme and am editing style.css to make the image wrapping work better. Originally if I tried to align an image to the left of the text, only one line of text would be next to the image. I looked at another theme and finally added the following to my style.css:
margin: 5px 15px 10px 0;
margin: 5px 0 10px 15px;
Now the first paragraph of my text is aligned next to the image properly, but the second paragraph of text is below the image. If the image is tall and narrow, I would like more than one paragraph of text to align next to it, not just the first paragraph.
