Hey Everyone..
I am looking for a web designing tool.The tool which helps me to design and understanding the page style easily.

Can anyone help me out?

As per my designing experience you can use Dreamweaver. It is very useful for web designing.Build standards-based websites with the industry-leading web authoring tool. Dreamweaver opened up rollovers and other DHTML behaviors for non-programmers. Dreamweaver CS5 integrates with Adobe BrowserLab, one of the new CS Live online services, which provides a fast and accurate solution for cross-browser compatibility testing.
