Question

If I don’t specify the width parameter for a jQuery modal dialog, what width will the dialog window have when opened?

$(foo).dialog('open') 

Is it 300?

Where is it specified?

Answer 1

In the jquery-ui.css CSS file, line 228.

If you’d like to override it, just add this chunk of code to your own CSS file and it should work:

.ui-dialog {
  width: 400px;
}
