Add the blend mode Styles

[elisa (elisa.kraus)]

Hello!
Can someone explain to me where I can set the Blendmodes in Webflow?
I have inserted the code in the Head Code.

But now i don’t know where i can set the “.mbm-multiply” for the Elements.
Is it in the Styles Area? Is it in the Selector Area?

Could someone Show ne some Screenshots?
