Waybar cava module

ive added the cava module to my waybar and added a space in between the blocks with this:

"bar_delimiter": 32

but the space character is not clear

02-42-25-10-15-2025

how can i make it clear?

I had the same issue for a while. What I ended up doing to deal with it was set

"bar_delimiter": 0

in my config.jsonc, which removes the delimiter (for some reason this still worked but a lot of other characters are just blocks, I assume it might be the same for you). Then in my style.css under cava I added

# cava {
...
letter-spacing: 4px;
}

This added a 4px space between each character.
