Simple KPI - CSS - Changing Font Size and entering space for Second Value

[kristen_qlik_noob]

I have a KPI where I would like to add a second value....how do I go about changing the font size of the second value and making a space between the first value and the second value so they can stack vertically without being smashed together? Thanks!

Current CSS:

& .label {
font-size: 150%;
color: black !important;
}
& .value {
font-size: 200%;
color: black !important;
]

Do I have to just create another KPI?
