I imagine this can be done by first placing it inside of the reference DIV, and then using position: relative .

So the animations on removal should work. I would like to have the default animation on removal, but can't get that to work. This is how I setup the RecyclerView: private void setupRecyclerView() {

I used following css for it: #foo { position: fixed; bottom: 0; right: 0; } It works fine with Chrome 3 and Firefox 3.6 but IE8 sucks... what can be a suitable solution for it? 回答1: This snippet works in IE7 at least <!DOCTYPE html> <html> <head> <meta charset=utf-8 /> <title>Test</title> <style> #foo { position: fixed; bottom: 0; right: 0; } </style> </head> <body> <div id="foo">Hello World</div> </body> </html> 回答2: I
