Is there a wireframing tool for web apps that can re-use my own custom CSS?

Question

I have been searching for and have not located (I fear it doesn't exist) a wire frame application that will use our current css for objects.

We have spent a lot of time perfecting our css to get the look we want, now I want to be able to use that css for new mockups without creating new objects each time we add something (as we would have to in photoshop).

In a perfect world, it would even handle the page layout so all that remains is the logic.

Has anyone heard of a tool that can do this?

Answer 1

I haven't used it, and I can't vouch for it, but https://alpha.easel.io/ might fit the bill. It's still in beta, but looks very interesting.

From their homepage: "Implement designs quickly using exact CSS properties rather than guessing from a mockup."
