which is the best tool for web designing

[debasis]

Adobe Dreamweaver is the best web development software tool available today, you need to learn use of it.

i have learnt HTML and i know little about dreamweaver.do know any site which teaches how to use dreamweaver to make dynamic website?and where to learn css and what is its use?

Ya there are plenty of e-books and video tutorials are available for learning dreamweaver but the thing is that you need to tackle it and coming to the point of CSS, CSS stands for Cascading Style Sheets, a new feature being added to HTML that gives both Web site developers and users more control over how pages are displayed. With CSS, designers and users can create style sheets that define how different elements, such as headers and links, appear. These style sheets can then be applied to any Web page.
The term cascading derives from the fact that multiple style sheets can be applied to the same Web page. CSS was developed by the W3C.

I am giving you one site where you can learn web designing freely Just Click Here.
Thanks.
