Defining viewport width & height

[Vingtoft]

Use case:
I'm server side rendering an Angular application where I use FlexBox (and of course domino as the server side DOM implementation).
My layout contains several show/hide, which is dependent on the width of the clients viewport.

The HTML returned by the server is therefore not the same as the HTML rendered by the client a few moments later. This results in the layout "flickering" and jumping around.

Setting width on the server side implementation of the DOM would fix this issue.
