Custom footer text height spacing

I'm looking to change the leading (spacing between lines) on the footer to make each line closer to each other.

Hi,

Option 1. When enter text, press Shift Enter, instead of using Enter to make new line

Or

Option 2. Add this to Design > Custom CSS

/* footer text spacing */
div#block-yui_3_17_2_1_1634928867370_8583 p {
    margin: 2px;
}

Thanks so much. @tuanphan You're the BEST.
