Button to footer not working

My button to the footer is not working.
There is a button to the contact form in the footer.
Link is #footer, but the link does not work. How can I add the “footer” CSS to the footer?

Hello, you can try to use the #colophon ID, not #footer.

Please feel free to ask any other questions that you might have.

Kind Regards, Roman.
