P[align] as p.
How to select elements with a certain attribute.
Testsheet:
P[align] {color: #cc0000;}
P[ownattribute] {color: #0000cc;}
The P[align] selector means "each element P with an attribute ALIGN". So the next paragraph should become red and the rest shouldn't.
Test paragraph with ALIGN=left. It should become red.
As to P[ownattribute], it's a test to see if non-standard HTML attributes are allowed. They are in Netscape 6, but Konqueror gets confused by them and makes all paragraphs blue.
Test paragraph with OWNATTRIBUTE=set. It might become blue.
A last test paragraph.
