This is how I specify my “blank” container in JavaScript:
Ext.create(‘Ext.container.Container’);
The following screenshot shows the style attribute my container has by default (the div in question is selected):

As you can see it has:
style="left: 0px; top: 9px; margin: 0px;"
- Where does this come from?
- How can I “clean” it to have no style at all by default? I didn’t specify
styleon the container so I can’t figure out where this comes from.
This settings comes from layout. If you want get rid of it you can specify
layout: autoin container config.Example: http://jsfiddle.net/rr2Vx/
