I need the code for my child theme functions.php

Hi there

I was trying to add some new code into my functions.php from my child theme and I believe I did something wrong and my site is not online anymore and this line appears when I try to see my site:
Parse error: syntax error, unexpected ‘<’ in /homepages/14/d585538234/htdocs/si/wp-content/themes/intro-child/functions.php on line 21
I am not very familiar with php code, could you please send me just the basic code I need to put into my child theme functions.php file again asap so I can see and keep editing my site again.

Many thanks
