Hi there,
add this CSS to your site:
.offside-js--interact .offside,
.offside-js--interact .offside-sliding-element {
-webkit-transition: -webkit-transform .2s cubic-bezier(.16, .68, .43, .99);
-moz-transition: -moz-transform .2s cubic-bezier(.16, .68, .43, .99);
-o-transition: -o-transform .2s cubic-bezier(.16, .68, .43, .99);
transition: transform .2s cubic-bezier(.16, .68, .43, .99);
}
In the CSS there are 4 instances of .2s
which is 0.2 seconds. Increase that to whatever you want in all 4 places.
