line breaks using html & trouble with functions.php

Hi guys,

I want to activate html in wordpress.
I use the customizr theme and followed the steps outlined
here

The person posting here has the same wish I have: Use line breaks on the front page.

However, as soon as I paste this recommended snippet into my child theme’s functions.php directory my site crashes.

This actually holds true for any snippet I’ve ever pasted into the functions.php directory. All I do is copy the table’s entire content and than paste it underneath the “paste underneath this line” line. Are you able to tell me what I’m doing wrong?
Or can you guide me to a way that doesn’t corrupt my site?

Thank you!
