Hi all!
Is it able to put
style="filter:alpha(opacity=10)" onmouseover="nereidFade(this,100,30,5)" onmouseout="nereidFade(this,10,50,5)" for the gradual highlight script in the css?

I'm currently working on a fully html-ed site as a practise (or revision) for html... so I'd like to know if the above code can be converted to put in a css.

Thanks!

style="filter:alpha(opacity=10)"
That part can, but the rest can't since it's javascript... don't think there'a another way you can do the fade in effect with CSS either.

So is it able to link to a js file in css?

No... you can link to a javascript file within your HTML page code, but not from within a stylesheet.
