Usage & Behavior
General guidelines
A popup window usually appears as a result of a user clicking a button, an icon, or a link.
Structure
A popup window consists of:
A colored header, including:
a title.
a close button (unless otherwise specified).
a help button (optional).
A content area, which may contain text, inputs and controls.
Buttons, including:
a primary action button.
a secondary action button, if relevant.
other action buttons, if relevant.
The popup appears over a semi-transparent black background with an opacity of 40%.
Placement and Positioning
The popup is centered horizontally on the screen.
The popup appears at 2/3 height of the screen.
The user will be able to move the popup around the screen.
The user cannot change the width or height of a popup window.
Content
Message headers will describe the object they are referring to (for example: Shifts). In some cases they may also contain the actual names of the entities (for example: Car Insurance evaluation form).
Dialog headers may describe the object they are referring to, or display action names (for example: Save as…)
if the header text exceeds the container’s width it will be truncate, showing an ellipsis (…). In this case, hovering over the header will open a tooltip showing the full header text.
In rare cases, button labels may change as a result of a user action.
Interaction
The popup can be closed by either:
clicking the close (X) button,
clicking the primary or secondary action buttons, or
pressing the Esc key.
Clicking outside of the popup will not close it.
For interactions within dialog boxes see Dialogs.
Validations and errors
Message popups do not require special validations.
For information about dialogs validations, see Dialogs.
Transitions
The semi-transparent background will appear and disappear with a fade effect.
The popup window itself will appear and disappear with a fade effect.
Best practices
Use
to display important information. Remember that popups can be intrusive.
Do not use
to display a large amount of content. In this case, link to another page or, in case of a dialog, consider using a Form.
to display unintrusive messages. In this case, consider using Toasts.
General
Keep the text short and informative.
Avoid opening a popup from another popup.
Accessibility compliance
Unless otherwise specified, see our general compliance information in Fundamentals - Accessibility.
Focus management
The tab index flow will follow the order displayed below. Shift + Tab will follow the reverse order.
In case there are more than 2 dialog buttons at the bottom of the popup, see example below:
If the content is not focusable, 1st item to get focus will be the Enter button.
The same logic order as above should apply even if any of the other buttons don’t appear.
Focus visual style on pop-up headers will have a different indication than other LUX components due to the background fill color:
Help, Informative, and Error will use a White color F/ocus
The warning pop-up will use a Black color Focus
