css has no negative effects on the caching of sites. css is good because it separates content from presentation which can have positive effects on a website (a couple are reduced page weight [which means faster load times] and by designing to standards it is easier to make changes later on)
the plus side of using css externally it is in one file not across multiple pages so there is only one place to change it. and it reduces that page wieght I mentioned earlier.
here's one previous topic on css pros and cons

Not really, I'm not a designer!
But it is my understanding that CSS totally rocks. Nothing to worry about SEO wise with it if you use it correctly and for good.

Your mark up code compared to table layouts can be reduced by over 50%. This must mean that the spiders can pick up your content, keywords etc much more easily and divide this from the markup code.

the linked file might not be found by spiders. You would need a script that uses HREFs to point to the linked file.

I highly recommend sticking all of your CSS in an external file. Because sooner or later you will want to redesign your site. When you do you'll find it much easier to upload one new CSS file rather than having to upload 100's or 1,000's of pages.

From my experiences, I would suggest going with a Strict DTD, as I find that it ensures the most consistency between browsers. Be forewarned, you will experience troubles with MAC IE5.x if you go the route of CSS-p no matter what DTD you decide upon. dithered.com should help with you with the various *hacks* that you might need to implement depending on the complexity of the layout.

However, there are more recent CSS developments that are much trickier to use, such as when a web designer tries to break completely with using tables to lay out a page and goes to positioned div layers. I find that to be totally unreliable in browsers over a few years old, and there are TENS OF MILLIONS of web users that still rely on old browsers such as NN4, IE4 and 5, and others. So while an advanced CSS page design may look great in the latest browsers, it falls apart in older versions, PARTICULARLY when the user scales their font size up and down (which all Mac users can do EVEN IF the designer tries to "lock" the font size, which is a bad idea anyway).
So for now, while I always use an external style sheet, I find that I still must use tables to lay out pages, much as I would rather not do so!
That said, CSS when used correctly has no impact on SEO other than reducing the overall amount of code on a page and potentially bringing the content "higher up" in the file.

those people aren't showing up in my logs...I'm just curious anyone out there seeing more than one percent of their visitors using NN4 or IE4 ?
besides the point that people using css for layout can quite easily provide support for these users...

Sweepthelegnate, you also hit the nail on the head when said that CSS can provide support for older browsers. It is true that the presentation will not be as slick looking but it can still completely functional, which is key. There is no reason to hinder the progress of Web development due to a few stragglers when CSS allows the option for the exact same site to work an all new browsers, old browsers and even mobile phones and PDAs.

Estimate for 2004:
709.1 million (Source: eMarketer)
945 million (Source: Computer Industry Almanac)
Projection for 2005:
1.07 billion (Computer Industry Almanac)
It is true you can present different versions of a site depending on the users browser, but it is extra work and I find that most websites don't bother. They just ignore those old browsers, which I think is a mistake. Every visitor counts.

I think it's important to point out not supporting these browsers doesn't mean the site is inacessible to those visitors.

I previously worked for Verizon Superpages and one of the frequently mundane chores was pulling browser analytic reports. Surprisingly, even in areas where one might be inclined to think that users are not as technologically advanced (i.e. rural areas) few were using NN4 and little to none IE 4.
For users who have a site with a more complex layout, it may be wise to use a hybrid mix of CSS positioning and tables, but I definitely would not be intrepid concerning CSS because you are concerned about browser compatibility. There are several workarounds and solutions for many issues concerning CSS and the browser war. Even the Library of Congress Web site uses and is currently in the process of transitioning the entire site to CSS layouts.
Besides, there are problematic issues even when using tables for layout in older browsers (particularly in Netscape 6 and older). It is definitely easier and quicker to solve certain layout issues with tables because they aren't quite as apparent with CSS. I have personally found that taking the time to figure it out has given me added flexibility for future expansion while still accommodating my visitors (considerably so with larger Web sites).
I do agree that every visitor counts, but I think it is more important to provide convenience and ease to your target audience. I would pose the question: "Would you build a Web site that may take twice as fast to load to accommodate a small percentage of your visitors or streamline it so it loads quickly for the largest percentage?" This may not always be the determining factor, however I think these sorts of questions are important to consider.
Just my two cents worth.
