Saw a discussion on this in Sencha Touch Fourm "Does anyone knows how to set the css -webkit-filter: blur(2px)".
But how to do this in ExtReact using the Themer tool or otherwise?

The idea is I want a modal
login dialog to popup and whatever was on the page gets blurred.

I am fairly new to Sencha and Themer so any examples would be appreciated.

Thanks,
