Alternate character sets / CSS code

Hello everyone,

I am trying to inject some CSS code in Rapid Weaver for alternate character sets. I work with Google font « Jost ».

It is said that Jost ships out-of-the-box with a double-storey “a”. To get the full Futura feel, we need to use the single-storey “a” alternate character with font-feature-settings: “ss01” 1 ;

I have not had any success with the following CSS code that I injected in my page :
.element {
font-feature-settings: “ss01” 1 ;

I know my problem is not related to Foundry, but I would be grateful if someone could propose a solution.

Thank you !
