Thanks for posting your design question. Is there any way you can provide some examples or screenshots? Also, if you’ve already began working on this effect, include your site’s read-only link and I’d be happy to take a look.

Hi @Revolution, at the moment, it is not possible to change the gradient via an interaction, so you can only change the opacity of the section element, not the opacity of the background color, background image or the gradient, at this time. Maybe in the future we will update this and add some more styling capabilities, we need to see how that fits in with some of our planned updates… we have had this request already and it is on our customer wish list
An alternate method to change the gradient opacity is to use jQuery and the CSS method to dynamically change any element or css property on your page, but it does involve some custom coding, which Webflow does not support (we only support currently implemented features). So while this can be done, and it is relatively easy to adjust css via jQuery, you still need to know jQuery and css and custom coding in order to accomplish this.
