ngDialog positioning and sizing - css

Question

I am working on a popup window using ngDialog. Here is some code:
<style>
.ngdialog.dialogforpopup .ngdialog-content
{
width : 1100px;
margin-top:-100px;
padding-top:10px;
}
</style>
Template
<div style="height:800px;width:1040px;padding-left:5px;padding-top:5px;
padding-right:5px"
</div>
<div class="ngdialog-buttons" style="margin-top:10px">
<button type="button" class="ngdialog-button ngdialog-button-primary"
ng-click="cancel()">Cancel</button>
<button type="button" class="ngdialog-button ngdialog-button-primary"
ng-click="save()">Save</button>
</div>
Directive
ngDialog.open({
template: 'editor.html',
controller: 'editorController',
className: 'ngdialog-theme-default dialogforpopup',
closeByDocument: false,
disableAnimation: true
});
I have two questions.
How can center my popup on the screen? Currently I am using margin-top:-100px;
Is it possible to size ngDialog automatically to its content?
Thanks

Answer 1

One can center ngdialog by setting "table-like" styles:
.ngdialog{
padding:0 !important;
}
.ngdialog-content {
padding: 0 !important;
background: transparent !important;
display: table; /*table-like styles for vertical centering*/
width: 100% !important;
height:100%;
}
.ngdialog-holder {
display: table-cell;
vertical-align: middle;
width: 100%;
height:100%;
}
.ngdialog-content > .ngdialog-close{
display:none; /*hide original close button*/
}
.my-dialog{
width:400px;
background:#fff;
border:1px solid #000;
margin:0 auto; /*center dialog horizontally*/
position: relative;
}
Also one need to wrap content of dialog with ".ngdialog-holder" and ".my-dialog" blocks. And finally place ".ngdialog-close" button inside of it.
<div class="ngdialog-holder">
<div class="my-dialog">
Dialog content goes here
<div class="ngdialog-close"></div>
</div>
</div>
Here is live example: ngdialog plunk

I downloaded ngDialog package using bower. so ngDilaog related CSS and JS files are in bower_components.
I added the following CSS and JS files to my html page.
<link rel="stylesheet" href="../bower_components/ng-dialog/css/ngDialog.css">
<link rel="stylesheet" href="../bower_components/ng-dialog/css/ngDialog-theme-default.css">
<link rel="stylesheet" href="../bower_components/ng-dialog/css/ngDialog-theme-plain.css">
<script src="../bower_components/ng-dialog/js/ngDialog.js"></script>
In my own JS file I am opening the dialog in the following way:
ngDialog.open({ template : 'dialog' ,scope : $scope , className: 'ngdialog-theme-default', plain: false,
showClose: true,
closeByDocument: true,
closeByEscape: true,
appendTo: false});
here is the html code:
<script type="text/ng-template" id='dialog'>
<div class="ngdialog-message">
Hello!!
</div>
</script>
With the above changes I am able to show the pop up on the center of the screen.
can use of the following class for pop up.
className: 'ngdialog-theme-plain'
className: 'ngdialog-theme-default'
I hope this will help!
