If readers are truly interested in the content, up and down scrolling is no problem. However:
▪You must gain the readers’ interest with the content that’s visible without scrolling. ▪You must keep the readers’ interest throughout the whole text, or they’ll stop scrolling and leave the topic without even having seen the rest. Therefore, good general rules are:
▪Start each topic with the main information. ▪Make sure that the main information is visible without scrolling. ▪If it’s possible, use expandable sections (toggles) to layer the information. If readers can grasp the structure of the topic at one glance, the topic isn’t too long. ▪The more important a piece of information is, the closer it should be positioned to the upper left corner of the window. ▪Don’t add any extra wide tables or extra wide pictures that require horizontal scrolling. Vertical scrolling is acceptable, but horizontal scrolling is not. |
