Change font-family for Big Title

I want to add a bit title with a different font for the theme fonts I’ve set. I’ve tried adding to Additional CSS with font-family: Parisienne, cursive;

But I’m also interested to see how other google fonts look but even this one isn’t working. What is my problem?

I’ve added it with the change of font and colour so that the full reads

#carousel-hestia-generic .page-header .container .hestia-title {
font-size: 35px;
color: #D6D6D6;
font-family: Parisienne, cursive;

}

It works for the font size and colour but not the font family
