Remarks

Known Issues

ContentDialog controls should be direct children of document.body. Otherwise, it is possible to mask event detection on the ContentDialog due to stacking context effects. This is because event detection for other elements is blocked while the ContentDialog is open. So, if the ContentDialog is a child of one of those blocked elements, it too will be blocked. This behavior is typical for all overlaying controls.

CSS classes

To customize the ContentDialog, you can define your own styles for these Cascading Style Sheets (CSS) classes (defined by the Windows Library for JavaScript style sheets):

CSS class	Description
win-contentdialog	Styles the entire ContentDialog.
win-contentdialog-backgroundoverlay	Styles the portions of the app that appear behind the shown ContentDialog.
win-contentdialog-commands	Styles the command buttons in a ContentDialog.
win-contentdialog-content	Styles the content portion of the ContentDialog.
win-contentdialog-dialog	Styles the dialog portion of the ContentDialog.
