Size does not change with Google Font

Hi, I am trying to change the font-size using CSS in the “custom CSS (optionnal)” field but it doesn’t have any effect. Font type and shadows work though…

I am using this CSS:

/* Page and Post Titles */
.title,

/* All other content headlines */
h2

{
font-family: “Parisienne”;
font-size: 20px;
text-shadow: 4px 4px 4px #aaa;
!important;
}

Can anyone help me changing the size of the text?
Thx!!
