Thank you so much!

How do I fix the empty heartbeats on the left?

Thank you so much!

How do I fix the empty heartbeats on the left?

I have this same issue. Currently working on a fix. It's odd because as soon as you go into the page editor mode they get fixed.

I adjusted Line 3 of the CSS Code to be .15 and it fixes the problem although it doesn't look as good now but it will do for now.

--max-item-width: .5fr; Adjust to --max-item-width: .15fr;

Thanks,

Some Tweaks ans Aesthetics added!
