The text added to the Next and Back Buttons in the Look and Feel will apply to the Next and Back Buttons on every page of the survey.
Every question, whether seen or not by the respondent, is calculated in the progress bar. If the respondent encounters logic that skips them to the middle of the survey, then the Progress Bar will jump to 50%.
Click into the text box labeled Questions per page and enter in a number to specify how many questions you would like per page. This is a great alternative to manually entering page breaks into your survey.
When the respondent clicks on a question, the question will be highlighted. This option is turned on by default. You can specify the color of the highlighter in the Colors tab.
The Question separator is turned on by default and adds space between questions. Edit the Question Separator item in the Colors tab to add a thin, colored line between the questions. If you would like to lessen the space between your questions, turn the Question Separator off by un-checking the select box.
