## update system
sudo dnf upgrade --assumeyes --refresh

## fstrim (on luks, no lvm)
  # 1. add 'rd.luks.options=discard' to /etc/default/grub (at the end of `GRUB_CMDLINE_LINUX="... rd.luks.options=discard"`)
  # 2. run 'sudo grub2-mkconfig -o /boot/grub2/grub.cfg'
  # 3. add `luks,allow-discards` too all encrypted volumes in /etc/crypttab (at the end of line)

You can now create a spinner using any of the variants below:

$("#el").spin(); // Produces default Spinner using the text color of #el.
$("#el").spin("small"); // Produces a 'small' Spinner using the text color of #el.
$("#el").spin("large", "white"); // Produces a 'large' Spinner in white (or any valid CSS color).
$("#el").spin({ ... }); // Produces a Spinner using your custom settings.

$("#el").spin(false); // Kills the spinner.
