Your Expertise Is Needed! (2) Issues I can't figure out

[faint birch]

In the attached image, you will see I placed a couple yellow arrows.

The first one is pointing to a "refresh" circle that pops up every 45-60 seconds and it's quite annoying. Does anyone know how either hide that if it's necessary, or stop it from showing up? I am using the custom:atomic-calendar-revive card to display my calendar events coming up. YAML: https://dpaste.org/WLmZd#L

The second one is pointing to a card that is forcing itself over top of my news ticker I created, which is supposed to be on top of everything. It is only affected by this custom:battery-state-card I am using, and what's weird is, I have the same card on the left side of my dashboard, and the news ticker is on top of that one. Just not the one on the right. I can't figure out why. YAML for battery-state-card: https://dpaste.org/TgwcW

YAML for my news ticker: https://dpaste.org/2qfOz

I don't know much about CSS but I'm going to make an assumption and say the problem is with the z-index.
The card of the left side (under the ticker) probably has a lower z-index than the ticker, but the card on the right has a higher value, thus putting it on top of the ticker. (Your first card will have a z-index of 0, the next 1, and so on.)
Looking at your ticker code, I think you need to add z-index: 99; to the ha-card section at Line 65.
This is what I've had to do to force cards to display on top of another card. (Stuff normally hidden but appear when active, for example.)
