CSS style delimiters not supported by Internet Explorer 6

1. Child Selector

H1> strong {color: red;} is invalid.

Only H1 strong {color: red;} can be used ;}

The subselector is not supported, but the subselector is supported.

2. sibling Selector

Invalid Li + Li {font-style: bold.

3. limited support for pseudo-class selector

A: Link: visited {color: # FFF;}, only recognizes the last one: visited.

It is best to write in the following order:

A: link {color: Navy ;}

A: visited {color: Gray ;}

A: hover {color: red ;}

A: active {color: yellow ;}

IE6 supports pseudo-class delimiters and is limited to hyperchains.

4 attribute Selector

H1 [Class] {color: Silver;} is invalid.

Not supported above. Eric Meyer's authoritative CSS guide pointed out that I have also verified IE6 SP1/Win XP in mainstream environments.

5. Eric Meyer says that Internet Explorer does not support multi-class delimiters correctly, at least not Internet Explorer 6.

. Warning. Urgent {Background: Silver;} is valid, not invalid.
