Full-Screen Page Loading Widget
Is it possible to customize the page loading widget so that
(i) it shows a dark backdrop over the screen (like a Dialog) ?
(ii) supports a back / cancel button that returns the user if they wish to abort the load process?
For (i), would this CSS do the trick, or is there a better way ?
.ui-loader {
padding-top: 40%;
width: 100% !important;
height: 100% !important;
left: 0 !important;
top: 0 !important;
margin-left: 0 !important;
margin-top: 0 !important;
}
thank you.
