How to edit Heroku application online?

How can I edit the application hosted on Heroku online? I need my remote HTML/CSS designer to do some layout fixes on my application hosted on the Heroku. Any help is really appreciated.

How do I access Heroku app?

Now that you've installed the Heroku CLI, open up a terminal window and type heroku login . The CLI asks you to enter your Heroku credentials, starting with the email address that serves as your username. When you're logged in, you can always check which user is logged in with the command heroku auth:whoami .

Can we change Heroku app name?

It is possible to rename an application by using the heroku:rename command. The application becomes accessible by the new name immediately, and the old name should not be used anymore to address it.

Currently, your best bet might be to Cloud9 to share and edit source code. You can deploy directly from Cloud9 to Heroku.

You cannot edit your application hosted on heroku online. If you have hosted your application code elsewhere on Github or Gitorious, it might be possible for your designer to make changes online there and then you can push the code to Heroku
