Uhm...can you explain this in pictures? lol

@Merenwench:
Every widget is now inside a container with class name "gpWidget", no matter what custom content box HTML you use. This makes it easier to standardize coding - I just updated the "hide this widget" code to work for everyone, so it's now one bit of code instead of the two I had before... this makes me happy 

@Aaron:
I noticed that the gpWidget container ID is all numbers. Because Firefox is compliant with the HTML4 standard, I can't use jQuery to target any ID that starts with a number nor does CSS using the ID work. Here is the quote from the standard:

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

But apparently in the HTML 5 standard this won't matter:

The id attribute specifies its element's unique identifier (ID). The value must be unique amongst all the IDs in the element's home subtree and must contain at least one character. The value must not contain any space characters.

I just thought I'd let you know... I don't think I'll need to use the ID anytime soon, so I wouldn't rush changing it...
