What steps will reproduce the problem?
1. CSS rule for an element with an id with a '.' character in
eg:
#MyForm\.myfield { ... }
<input id="MyForm.myfield" ... />

Defines this as valid CSS.

Debian 6 ('Squeeze')

Which version of Apache?

Oh, I see, this is a problem because #Myform\.myfield specifies id 
Myform.myfield, whereas #Myform.myfield specifies id Myform with class myfield.

Thanks for the report, I'll look into this.

I've noticed another problem along similar lines.

When trying to filter by element id in quotes, the quotes are removed, meaning 
that the effect is the same again, the rule is treated as ID.class instead of 
ID.MOREID

Eg:
input[id="MyFrm.MyField"]

gets compressed to

input[id=MyFrm.MyField]
