The objective is so that the end users can see all the links, without having to click, only float across the topics to see where this takes them. After the pages load the first time, this does exactly what I needed, but the initial Java Loadtime (I assume Java) takes up to 5 seconds on screen (with T1), and I am getting complaints about the initial blank screen for such a long time. Can the code that has been inserted from the Dreamweaver simple tools to create these menus be changed into better code, or am I just doing something stupid?

Not big enough to take 5 seconds over a T1. If anything, a CSS should speed up your pages, because it cuts down on the minor bloat you get from all the <font> and <style> tags. Start adding DHTML or Java Script in addition to a CSS, and it could get pretty complicated. The time lag could be a server issue, or your PC itself... The T1 line will only transfer the files off of the server as fast as the server will allow... and JavaScript is processed in your browser locally... so that may be part of it. I don't know that I'd call it stupid, but it sounds like the kewl factor is overshadowed by the increased load time... and maybe not worth it for your site... _____________________________ If con is the opposite of pro, is Congress the opposite of progress?

If you have one main table, with nested tables inside, there will be a delay of anything showing up until the main table loads. The option would be to use individual tables for some things and "stack" them, rather than nesting. In a large majority of cases, the CSS is not the cause of a delay in load time.

If you're talking about what I think you're talking about then it's a script based menuing system that also uses css. The delay is caused by the size of the script rather than the css. With css there will be a small initial load cost, thereafter none as it is cached. A way of reducing the page load time on all pages after the first one your visitor sees is outlined here: http://www.htmlgoodies.com/beyond/extjs.html however I have to say that if you're on a T1 connection the download time (assuming a moderately ok server) should be negligible - sounds to me like the script is massive - you might like to think strongly about the last point bobby made. I am on a very very fast connection. in effect I sit a the end of a datapipe. With that sort of render time I simply leave. - Visitors on an ordinary connection are likely to too. < Message edited by gorilla -- 11/14/2003 7:35:06 PM > _____________________________ Mh�ircaish Signature self-censored to protect the sensibilities of the thin-skinned .
