Hi,
Sorry for your trouble.
Please use the following code in your custom CSS:
#sp-top-bar>.container>.row {
align-items: center;
}
This should fix the alignment issue of your topbar.
Moreover, you can create the whole section in SPPB editor as a SPPB module, then publish that module in your top position. Right now you are using 3 column for your topbar, but later you need to single column that covers the full space to hold your SPPB module where you would create the whole section. If this is what you wanted.
Thanks!
