Hello friends, i just want to know that which software or tool is best for designing table less css and xhtml pages.
Thanks in advance for your help.

I don't know if there is a best software. It is just a matter of what you are comfortable with. People usually become accustomed to a certain piece of software, and then stick with it because of knowing its shortcuts and methods well.

I use Dreamweaver for the most part, but I don't think it is something that beginners should jump into (I don't know what your particular skill-level is). Dreamweaver is somewhat expensive, which is a good reason not to start with it. It is also over-featured, so novices tend to be drawn towards its bloated features instead of spending time learning the guts of the code as they should be. Dreamweaver doesn't generate very clean code on its own, and I can always spot when it is being used incorrectly because of the odd way it forms documents.

The best thing to do if you are starting out, is learn to write HTML and CSS without using the aide of anything complex. After all, code is nothing but a text-file, and HTML editors nothing but an advanced text-editor. If you can create a site "blind", then later you will be able to take advantage of a more powerful application.

wayfarer makes a good point.. Really, and esp if you are just beginning, it is better to learn to do everything by hand. The only reason I still use Dreamweaver is because of some of its more advanced features and the fact that it gives me code hints. For the most part, I write all of my code from scratch. That way, I can make sure the code is coming out the way it should.

Most WYSIWYG editors will allow you to make table free layout if you know how to work it.. for example, you can change a few settings in Dreamweaver and it will use nothing but div tags in place of tables. However, unless you are in a hurry to get your site going or just dont care enough about your code to get it right (which it appears you do care), then I would recommend using something similar to notepad (preferably with syntax highlighting) or Dreamweaver in code view.
