• Your thumbnail should be 312px (width) by 268px (height)
  • The thumbnail should be a simplified vector representation of the component on a white background as it will appear when it’s in the editor view.
  • Please use the following grays (from lightest to darkest) to create the representation of the component.
    • #EEEEEE
    • #E0E0E0
    • #BDBDBD
    • #9E9E9E
    • #757575
  • Try to avoid text. Instead what works well is just using rounded rectangles as a simplified version of “text”.
  • Can’t be a GIF.
