silver11 on "error - text content shifted right"

Hi
I have no idea how it happened, because the only thing I touched was an image in my library that I was trying to re-size, but somehow I have shifted the Indents on my Sidebars text.

Also, although I did not succeed in changing the size of the image I was trying to change, I have reduced the size of the top 2 images in my right sidebar without even touching them!

I am as keen to find out what I did wrong as to restore the site to how it looked previously.

Would be very grateful for any insight into the problem?
Many thanks
best wishes Trisha
