I think I did it! I wanted to create a blog page on a white background, and thanks to some contributors to the Mandigo Wiki, the answer was right there. So, instead of having a blog that looked like a page of something on a colored background, I got rid of the “page” look and turned the background white. Then I turned the background for my posts a shade of purple (of course!), because too much white is well, too much.
Which of course then meant I needed to update my image script, because I like drop shadows, and a drop shadow image has to match the color it’s sitting on. Thusly:
So now, let’s see if this works correctly. Feedback welcome! Does everything look right? Let me know!
