Used options for modifying embedded card form's. Form disappeared.

I used the options for modifying embedded card form's and now my form has almost disappeared.  I changed the height because there was too much space above and below the form (in the embedded area).

Now the pencil is not viewable and I can't change it back. How can I fix this?

Also, is there a support page on using this option tool to send me to?

Thank you!

Solved this by clearing browser cache and when I refreshed, clicking really quickly before the form shrunk (on the pencil) and made the changes.

It's good to know that the concern has been resolved already.

With regards to the support page you mentioned, you can always post your concerns on this forum and we'll be responding to it as quickly as we can.
