Alert dialogs display important information that users need to acknowledge. They appear over the interface and block further interactions until an action is selected.
All alert dialogs must have a title. The title appears in bold at the top of the dialog and uses a few words to convey the outcome of what will happen if a user continues with an action.
Alert dialogs can include a description. A description briefly communicates any additional information or context that a user needs to know in order to make one of the decisions offered by the buttons.
This is the default variant for alert dialogs. Use a confirmation variant for asking a user to confirm a choice. This alert dialog has an accent button to highlight a strong preference for which action to take.
Warning alert dialogs communicate important information to users in relation to an issue that needs to be acknowledged, but does not block the user from moving forward. It has an orange warning icon near the title to reinforce its importance.
Destructive alert dialogs are for when a user needs to confirm an action that will impact their data or experience in a potentially negative way, such as deleting files or contacts. This alert dialog has a red (negative) button to highlight the destructive action.
Error alert dialogs communicate critical information about an issue that a user needs to acknowledge. This alert dialog has a warning icon to reinforce its importance.
An alert dialog must have at least one button. The primary action label is for the first (right-most) button. It communicates what the button will do with a short, actionable phrase to either describe the next step if selected, or to acknowledge and dismiss the dialog.
An alert dialog can have a total of 3 buttons if the secondary outline button label is defined. If left undefined, the button won’t appear. The secondary outline button label communicates what the button will do with a short, actionable phrase to describe what will happen in the next step, if selected.
An alert dialog with a button that offers an option to go back and cancel the action will have a label of “Cancel,” by default.
From the design point of view, each component has a number of options. These options and their names are platform agnostic, and each implementation should adapt these to fit into their framework.
confirmation / information / warning / destructive / error
|primary action label|
|secondary action label|
If undefined, this button does not appear.
|cancel action label|
If undefined, this button does not appear.
When the title and description text are too long for the available horizontal space, they wrap to form another line.
An alert dialog can have up to 3 buttons. When horizontal space is limited, button groups stack vertically. They should appear in ascending order based on importance, with the most critical action at the bottom.
Alert dialogs are interruptive, so they're best for displaying important information that users need to acknowledge before moving forward with a task or workflow. Use them only when absolutely necessary, not for low-signal notifications or excessive confirmations.
Alert dialogs are meant to interrupt the experience until a resolution is reached, so there should only be one displayed at a time. Don't open an alert dialog from within another alert dialog. If the situation seems to require a sequence of decisions, look into using a different design altogether.
Writing for alert dialogs starts by determining the nature of the message. Each Spectrum alert dialog variant has its own communication goal and tone that work in partnership with its visual design.
|Alert dialog variant||Goal||Tone|
|Confirmation||Asking a user to confirm an action they want to take.||Instructive|
|Information||Sharing important information that a user needs to acknowledge.||Helpful|
|Warning||Sharing time-sensitive information that a user needs to consider, but won’t block them from proceeding.||Instructive to helpful|
|Destructive||Telling a user that if they are to proceed with an action they want to take, it may impact their data in a negative way.||Instructive|
|Error||Communicating critical information about an issue that a user needs to resolve before they can move forward with a task.||Supportive|
All alert dialogs must have a title. The title communicates the upshot of the message, such as the eventual outcome or conclusion of an action. It should be as close as possible to a complete sentence (subject + verb). Don’t use punctuation at the end of the title.
Most alert dialog titles communicate the main effect of whatever a person is about to do. Titles ideally use the same or similar phrasing as the call-to-action that had led someone to the alert dialog in the first place.
The title of an error alert dialog communicates the result of the error. Don’t just state that an error has occurred.
Alert dialog descriptions share any additional information or context that a person needs to know in order to make one of the decisions offered by the actions. Descriptions are written in complete sentences, and any error code is included in parentheses at the end of the last sentence.
Use a short phrase to succinctly describe the options for next steps. If possible, have the button label use the same language as the action mentioned in the alert dialog title (e.g., if a dialog's title is “Delete conversation,” its primary action button label would be “Delete”).
For alert dialog buttons, make the labels as specific and actionable as possible. Even if someone were to only read the word or phrase on the button, they should be able to get a summary of the alert dialog’s entire message.
Questions in alert dialog titles — such as “Are you sure you want to quit?” or “Do you want to cancel?” — are redundant and undermine a user's agency in the decision they've already made by taking a previous action to get to the alert dialog. This phrasing also sets up for a yes/no set of actions, which can become confusing. Instead, reframe the message to focus on the outcome or effect.
It’s OK to ask a question in an alert dialog's description to confirm if someone wants to go ahead with a choice that the system is making on their behalf. However, this should still be paired with distinct actions that show that a person has control over what happens next.
For RTL (right-to-left) languages, the layout of the alert dialog is mirrored. Texts are right-aligned and buttons are left-aligned.
|Tab||Moves focus to the next button inside the alert dialog (last becomes first). If none of the buttons are selected, the focus is set on the first button.|
|Shift + Tab||Moves focus to the previous button inside the alert dialog (first becomes last). If none of the buttons are selected, the focus is set on the last button.|
|Esc||Dismisses the alert dialog. This is equivalent to choosing “Cancel” or an “OK” confirmation.|
