After changed my web's code with DIV+CSS,(use witer txt) the size of our web's home page code had changed from 65K to 15k. It's really a good behave in simplified codes So the first effection of this change is more fast to load now. And now I am Just wait the gift of search engine. Wish we will have more good rank in search engine. If there will be a good effection may we will take more time for it.(may for W3C) And I suggest more webmaster can "write" there web with DIV+CSS! Just wait for the result as a test !
I don't know what Writer is, but a normal text editor is all you really need. Well, you also want a copy of each major (popular) web browser: Internet Explorer 6 and 7, Firefox 2 (Mozilla), Safari (Safari is a Macintosh browser but there is Safari-for-Windows you can download), and Opera. These are all free. If someone in your company has a Unix/Linux machine, testing in Konqueror web browser is not a bad idea. Good to hear that your web site is smaller now, but DIV+CSS is not magic : ) The search engines will come if you wrote the pages well. The name of each page on your web site should be in a <h1> tag</h1>, and sub-headings in <h2> and <h3> when appropriate... the page should be structured (header, sidebar, menu, footer) and it should make sense when CSS is off (search engines cannot see CSS effects). Good luck.
