style by card-title

[flyibeat]

It would be very useful if there could be a possibility to add custom style to a card-title separately.
like this

Sometimes I use it with other Lovelace
like this

The space between them is a little big

The left and right clearances also need to be adjusted separately，like this
.container｛
margin-top： 0px；
margin-bottom：0px；
｝
.row .col {
padding: 0px 0px;
｝
