change subheading styling

Hi,

I can only change the color of the subheading with the following custom css, but I also want the font, weight, size, and case changed.

.av-subheading {
font-family: ‘Montserrat’;
font-weight:400;
font-size:17px;
color:#e68903;
text-decoration:uppercase;
}

Google Font is loaded, and I’ve also tried by adding ” !important” to each rule… It doesn’t work.
