Custom css not working

I use default theme. and want to adjust line height.

:root {
–ct-text-size: 32px;
–ct-line-height: 3;

I found some css code and put it on custom css. And it doesn’t work.
andy help?

Have you tried this?

:root {
font-size: 32px !important;

Oh, that work, for font size. Is there any way to change line height also?

I would try this first -

Hm… it doesn’t work, line-height is still same but font size changed.
