I would like to create a well area on my page that makes the area look like it is a little bit below the page by a few pixels. My page currently has a white background and a #F5F5F5 well area. 

I looked at the well for twitter bootstrap:

```
http://getbootstrap.com/components/#wells

```

For me at least this does not look like well at all. Maybe it is because I know the focus of the later version is to create a flat effect. 

Does anyone have any examples of how I could add a working well effect?
