Why can @import be at the top only?
A style sheet that is imported into another one has a lower ranking in the cascading order: the importing style sheet overrides the imported one. Programmers may recognize this as the same model as in Java, Modula, Object-Pascal, Oberon and other modular programming languages.
However, there is a competing model, well-known to C programmers, where the imported material is not lower in rank, but is expanded in-place and becomes an integral part of the importing document.
By allowing @import only at the top of the style sheet, people that think in terms of the second model (although in principle incorrect) will still get the expected results: as long as the @import is before any other overriding rules, the two models are equivalent.
Btw. In all the modular languages import statements are only allowed at the top. In C, the #include can be put elsewhere, but in practice everybody always puts it at the top. So there may not be that much need to allow @import elsewhere in the style sheet either.
Colored Horizontal Rule?
You can apply styles to Horizontal Rules
<HR>
in IE without problems, but NN4.xx can only render the silvery HR. But there is a way around it:
.rule {border-top-width: 1px;
border-top-style: solid;
border-color: #FF0000;
margin: 0px 2%;}
that, applied to a div, should give you a red HR in NN4.xx and IE, with a 2% gap on the left and right side.

On this page is an Example of a coloured ‘Horizontal Rule’.
Update:
Thanks to Matt Del Vecchio here is an improved format for the Horizontal Rule:
hr { height:0px;
border:0px;
border-top:1px solid #ff1493; }
….this works in both IE and Netscape. It tells the browser to not render the hr rule itself, and then sets a 1px border, which looks just how most folks want to render the hr rule. It uses the
element and that is better than writing your own class as all devices will know what to do with an
tag.
Do URL’s have quotes or not?
Double or single quotes in URLs are optional. The tree following examples are equally valid:
BODY {background: url(pics/wave.png) blue}
BODY {background: url(”pics/wave.png”) blue}
BODY {background: url(’pics/wave.png’) blue}
To what are partial URLs relative?
Partial URLs are relative to the source of the style sheet. The style sheet source can either be linked or embedded. To which source partial URLs are relative to depends on their occurrence.
If a partial URL occurs in a linked style sheet then it is relative to the linked style sheet. The URL of the linked style sheet is the URL of the directory where the sheet is kept.
If a partial URL occurs in an embedded style sheet then it is relative to the embedded style sheet. The URL of the embedded style sheet is the URL of the HTML document in which the sheet is embedded.
Note that Navigator 4.x treats partial URLs as being relative to the HTML document, regardless of the place where the partial URL occurs. This is a serious bug which forces most authors to use absolute URLs in their CSS.
