Downloading the source of my Heroku site from Heroku?

I built a Ruby on Rails application that is running on Heroku.

For reasons currently unknown to me, the page formatting of my web app has gotten a bit messed up on my local source code, and I'd 开发者_如何学JAVAlike to download the not-messed-up copy from Heroku, and work with that instead.

Is there any way to do this? Thanks in advance.

By the way, I tried downloading the CSS files from the Heroku hosted site, and it still doesn't look right.

You will need to clone it:

git clone git@heroku.com:your-app.git
