Use popovers to show a longer text, or when you want to have a link to an external web page. It is shown when the respondent clicks on a word or icon. The window remains visible until they click again outside of the popover.
Use modal windows to display a long text, images and links. This creates an overlay that covers a large part of the screen. The background becomes darker so that the focus lies on the window. Respondents click on the X in the top-right corner or outside of the modal window to close it.
Operator: determine what you want to use a 1) tooltip, 2) popover or 3) modal window.
Active text: this is the text that reacts to either the hover or click. Leave the space between the double quotes empty when you only want to display an icon.
Contents: this is the content that will be shown in the tooltip, popover or modal window.
Position (optional): use a position to determine where the contents must be shown (only for tooltips and popovers).
Icon (optional): show an icon as trigger instead of text.
