A Modal control displays a panel of information above your app. It can contain a header, detail or footers. By default, it is hidden, so it cannot be seen in the Design Screen. It needs to opened using its toggle function.

Since it does not display on the Design Screen, it can be difficult to edit. There's an easy solution. Add 'display:block' to the style attribute. Don't forget to remove it when you are done.

Make it the bottom control in the list of controls in the Project Explorer. That will it will float over the other controls without affecting their placement.

It can also act as a container for child controls.

Keep its width set to 'auto'. Bootstrap will size it properly. Do not set the screenMode of the containing Form to Zoom.
