To ensure understanding of readers, always use the arrows in pair by placing them at either end of the marquee with a transparency of about 30% opacity. Do not color the arrows. These icons serve only as visual prompts, not buttons to trigger movement.
Possible directions for this interaction: vertical, horizontal (note that vertical mode with the ⅙, ⅛H and banner formats is not permitted).
- The scrolling marquee must not be an infinite loop.
- Use the 65 px arrows (at around 30% opacity) for full-screen, half-screen, 1/3 vertical and 1/3 horizontal ads. With smaller ads, use the 40 px arrows (at around 30% opacity).
