after some time I'm asked to work on a heavy web-project I did (layout, html/css) about a year ago. There are some changes that have to be made, basically some css and js stuff. By now the whole project was turned upside down by the developer. It gives me a hard time to connect to the work of him, especially because my old files and file-structure won't work anymore. Thats why I need a up-to-date working-environment, but I don't want to change the files on the server directly. Need some testing and improving while doing this.

So, what is your workflow in such a case? Thought about copying the whole/parts of the server to a own homeserver. But even that will be a big task for me (I'm more the front-end-guy). Would be great if theres a way to shrink it down (php, mysql,...), since I only need to change some css/html javascript. Are there any tools available?

Love to hear how you handle such situations.

Thanks a lot!
