Ask HN: How do you "design then code"?
So I want to build my own web app, and after reading Getting Real by 37signals, I'm inspired to build mockups before actually adding the functionality. I have two questions though:
1. They (37signals) say that you can make the design with HTML and CSS. What are the good tools to facilitate this process? I guess I could write stuff from scratch, and I've found some tools that help you make mockups, but what are the best ones?
2. How exactly do you add the functionality with the design? For example, let's say I want to make a web app using Ruby on Rails, and I make the design for it. I can then create a rails project and build the functionality, but how can I tie the actual functionality with the front-end? I'm sure this is a long answer as well, so if you could recommend a place where I can read about it, that would be wonderful.
Thanks in advance for all your help.
