I am putting back some of my old posts (~1999) after review and corrections. Excuse Spelling, Grammar and Content mistakes.

• Keep information 3 clicks away to improve accessibility, have a search and site map too.
• Html tables can be sized with % and not by pixels, so that it can resize according to different computers of say 1024*768 and 800*600. use pixels for single columns only or when you put all in a 740px limited page.
• FTP not working use passive mode for fire walled sites. Use Filezilla.
• Avoid frames even iframe of dhtml, use the noframes option. Main problem is that visitors cannot get back to your frames site after finding a nice page on the search engine, or keep a link on every framed page to home index.html with '_top'.
• Webpages should be usable, at 1024*768 and 800*600. viewable by mozilla 1.0+ and IE5+, most used vga settings are 1024*768 high.
• The KiloByte weight of a single web page with images, flash, js and css could be a max of 100 kb for up to 10,000 views per day, 200 kb for 1000 visitors per day, 500 kb if you have only 10 visitors per day. Due to bandwidth requirement of server and other bottlenecks. A page of 500 kb will cause great frustration to some users at busy times and poor connection. Use >1Mb pages only for Intranet or offline work.
• Always keep your local website in one folder like 'myweb' all sub folders within that, to a large extent use lower case, 8.3 format like anewpage.htm, .html and .js etc. If you use long file names do not use space in file names or folders, try something like my-best-book.html.
• Images should be like ../images/cat.gif or pictures/jug.jpg. not like file://d://myweb/images/cat.gif this will not work url should be 'relative' only or 'absolute' like http://www.sun.com/jug.png.
