Axure RP is a powerful prototyping tool for front end, web, and workflow designers to create wireframes, prototypes, workflow diagrams, and more. There is no coding required.
This tool reminds me of Adobe Illustrator in how you can modify vector shapes using points. I love having that level of control especially when tweaking icons. Axure has terrific documentation, too; yet, my CSS knowledge likely made it easier for me to learn how the widgets work.
