newb questions

please forgive these questions if they are obvious, but if you dont mind clearing something up for me:

1. is it possible to include html or javascript inside a css file? if so what is the format?

2. is it possible to use the hover or link properties of one css element to change the properties of another css element which is not a subset of the first element? (eg?)

thanks for your indulgence...

No to both.

Always keep in mind that CSS is not a programming language and cannot modify anything. CSS stands for "style sheet".

Would
Not work?

He said not on a "subset" of another element.

righto . . .

if i had
<span id ="element1">
<a href="#null">something</a></span>
</span>

<span id="element2">some stuff</span>

then the above-mentioned css wouldn't do anything...
(right?)

Correct. It's the "cascade" part of CSS. If you want to refer to other elements of the page, then you would need to reference the DOM (Document Object Model), and the only way to do that is with javascript, a programing language.

There are "selectors", in CSS, which are methods of affecting sibling elements in the same cascade, from parent through child, but I don't think that's what you want.

thanks for the lesson . . .

crystal clear now . . .
