Here are some examples I have collected:
.toast.green{ display: none; }
.tile.weather .tile-footer { font-size: 0.8em; }
.tile.clock .time { font-size: 1.8em; } .date { font-size: 2em; }
.tile .title { text-shadow: none; }
.tile .title { line-height: 110%; }
.tile .tile-footer { text-align: center; }
.tile .tile-footer .status span.right { float: inherit!important; }
