+## Design
+
+- Dialogs have a max width of 560px. Alert and confirmation dialogs got a fixed width of 320px. If you need more width, consider a dedicated page instead.
+- The close X-icon is on the top left, on all screen sizes. Except for alert and confirmation dialogs, they only have buttons and no X-icon. This is different compared to the Material guideliness.
+- Dialogs can't be closed with ESC or clicked outside of the dialog when there is a form that the user needs to fill out. Instead it will animate "no" by a little shake.
+- Extra icon buttons are on the top right, for example help, settings and expand dialog. More than 2 icon buttons, they will be in an overflow menu.
+- The submit button is grouped with a cancel button at the bottom right, on all screen sizes. Fullscreen mobile dialogs have them sticky at the bottom.
+- Keep the labels short, for example `Save`, `Delete`, `Enable`.
+- Dialog with actions must always have a discard button. On desktop a `Cancel` button and X-icon, on mobile only the X-icon.
+- Destructive actions should be a red warning button.
+- Alert or confirmation dialogs only have buttons and no X-icon.
+- Try to avoid three buttons in one dialog. Especially when you leave the dialog task unfinished.
