Dynamic Behaviour of Dialog Box component is not working.

Hi all,

Dynamic Behaviour of Dialog Box component is not working, when we change default styles to our custom styles.

i.e,

If i change the width and height of Dialog Box and when we minimize or decrease the browser window , Dialog Box is not auto adjusting dynamically to current browser size.

When I  use default dialog styles, functionality is working fine.

Please provide some inputs on this issue.

Thanks
