Reduce size of Form Block for Post-Submit

Hello,

I have a form block that is sized correctly for the original form. However, once you submit it, the size of the block remains the same. I would like to reduce it so that it fits the Post-Submit text.

https://www.karen4kansas.com/connect-1 - please put test in the form fields if you fill it out.

I'd also like to customize the color of the post-submit block and the text if possible. 

Also that blue box sometimes appears and sometimes doesn't. Any ideas? Thank you!

Hi,

The page url doesn't exist. Can you check it again?
