It can also mess with the layout of other theme components below, like the light rope from Christmas Decoration Component 🎄.

Two solutions here:
Either remove the margin-bottom from the Welcome Banner component if it has no use or add a display: none; on the Welcome Banner when the requirements for it to be displayed are not met.
