Please describe the issue
I would like to set dialog's width property but it's not setting width. Every time it's taking 450px which is coming from below class.

.ngdialog-theme-default.ngdialog .ngdialog-content

What did you expect to happen?
width should be set in px or in percentage.

What actually happened?
width is not set for px or percentage.

The version of ngDialog you are using is quite old, and a quick look at the code suggests that the feature you are trying to use was introduced in a later version:

2b15adc

You can confirm this by using a recent version (like 1.4.0) of ngDialog in your Plunkr.
