Pages

From skylightwiki

You will notice in the question editor that there are tabs labeled "pages". These tabs denote what questions will appear on a single web view. Although there is not limit to the amount of questions you can place on a page, if there is more than a screen full the respondent will have to scroll down. Which, if responses are not required it might be the case respondents dont scroll down and miss some questions....

You can title pages, and you can choose whether or not respondents can see those titles. It's often a good idea to let respondents see the titles, to help frame the questions they're about to read.
