Hello there,   How would I go about creating 'masks' on the sides of my page where the elements slide in? I see this done very well on this infographic   https://www.ceros.com/examples/visage-data-storytelling/   Thanks in advance   EDIT: Obviously I am new to use lots of tweens on 1 page - is there a way I can minimize my code?   Cheers See the Pen gmeXxY by erayner (@erayner) on CodePen
