Underslide

What is an under slide?

The underslide is a fully responsive, high-impact, expanding ad unit, consisting of an open and closed state

  • Sliding in from the bottom, the closed state occupies a maximum of 100px height and 100% of the width of the device screen. A close button is automatically added above the creative, as shown

  • Open state occupies 100% height and 100% width of the device, with a close button bar (35 pixels in height) sitting at the top

Note Do not place important content within the background/image area as this will be cut off on smaller devices. Please keep all logos, content and CTA to the creative area only

How do I design the closed state?

  • Dimensions 600 x 150px

  • Must contain a clear 'tap to expand' message that will be legible when viewed on mobile
