Looking for purple heart divider

Hi There - I am new to this theme and just beginning the process of setting up my sight. the lovely purple heart divider has seemed to have disappeared from the template…how to I find this, reinstall it, or whatever it is I need to do to get it back up on my front page? Thank you!

<hr class=“section-divider”>

I tried to past your code when editing a page and I just got the code. Can you provide a bit of instruction as to what to do with <hr class=“section-divider”>
Thank you!

Do not copy and paste, type, after work, you can copy and paste.
Test with single quotes also
<hr class = ‘section-divider’>
Here both work.
