Making Website Mock-Ups in Linux?
The Ubiquitous Web Designer asks: "I am trying to design a rather complex web page and am wondering if there are any tools which will allow me to make non-functioning mock-ups of each page so that a programmer can work from them. Obviously, it's hard to use the GIMP to make radio buttons, check-boxes, data entry fields, and so on. Can something help me design a page without much knowledge of HTML, or am I better off just doing it with paper and pencil by hand?"
Try Nvu, it's good enough.
Inkscape is perfect for this sort of thing. I've used it many times.
What if I do the same thing, and I do get different results?
Please do not do what you've asked about doing. Instead, pick up a copy of Paper Prototyping at http://www.paperprototyping.com/ then read it, and then you will save yourself a huge amount of time (much more than the time you take to understand the concept).
