3.5.1, drop shadow not showing in Safari and Chrome
 

Firefox shows the drop shadow around the container quite nicely, but I'm not seeing it in Safari or Chrome. I haven't checked it in MSIE yet. This is how it looks in Chrome:

CSS3 has yet to be fully integrated in many browsers.

Well I am having an issue even getting the drop shadow to appear at all.

I did it fine on http://musingmainiac.com, but that was when the drop shadow was a feature in the theme options.

I added what I thought was the code in layout option, but it does not show here: http://notjustbabybrain.com

Any suggestions?

I see the drop shadow in both.

I had the same issue with my blog. In the Style & Configure LAYOUT option I had to add "-webkit-box-shadow: 0 0 15px #333;" to get the drop shadow to show in Chrome. Strange that it wasn't previously there, but that line fixed it for me.
