Need Basic CSS Help for Subscribe Box

My orange subscribe box looks good on my computer but when I switch to one with a bigger screen, the get email updates, and the pictures and links go to the right of the picture. I want them to be below the Rss guy picture no matter what. How do I do this?

Also, the images in my box are a little above the text. How do I fix this also?

Thanks a lot!
