Bug: set width of layout

Run the index.html, the width of layout doesn’t work?
What I used is right?

app.js (204 Bytes)
index.html (420 Bytes)

Please, note that you need to define the sizes of your layout container:

    <div id="layout_container" style="width:300px; height:800px">

I want create full screen application, is there a sample to use layout for full screen?

In this case it makes sense to attach your layout to the html body, not to the div on your html page.
or you may set the sizes of your layout container to 100% height and width.
