This is a Chrome Devtools Extension that tracks changes you make via the inspector and provides a convenient "patch" style listing of the changes so that they can be easily shared.
This grew out of our own frustration with how we worked with designers or art directors. Typically we'll get a screenshot emailed to you highlighting the changes they want made so that their layouts are "pixel perfect".
Once these design types are introduced to the inspector they find joy in the ability to endlessly play & tweak values, but we found that there was still no good way to convey the changes they made back to us. We started getting email with screenshots of the inspector highlighting the changes, a little better than just a marked up screenshot but still a pain to merge the changes back into the code base.
We investigated all of the live-edit style CSS systems, but they're all so much overkill for what we need and require lots of complicated setup. They just wouldn't work for design types.
After discussing the problem around the studio for a couple weeks we figured that if we could just get a patch style output of the differences emailed to us, or provided in a ticket, then a developer could easily grok the changes and manually merge them back into the code base.
And voila. This extension was built.
You can install the extension directly from the Chrom Web Store:
https://chrome.google.com/webstore/detail/css-diff/bnkooidmjbobfbgncondmfoajbpafjio?hl=en
Clone this repository
Open the Chrome extensions page by typing the following in your address bar:
chrome://extensions
Ensure Developer Mode is enable (top right)
Choose
Load Unpacked ExtensionSelect the directory that was created when you cloned the repository
Once the extension is installed just open and use the devtools window as you
normally would. You'll notice that at the top is a new Tab that says CSS
Diff, when you visit it you'll be given the patch style output of your
changes.
The initial & modified resources are tracked when the devtools panel is opened and this means that if you make modifications, close the devtools panel, and then re-open the devtools panel we'll consider the current state the "initial" resources. Once you start to make changes do not close the devtools panel or you will most likely need to reload the page and re-start all of your changes.
This only works with uncompiled/unminified CSS sources because we're actually running a diff on the raw source in the inspected window. This shouldn't be a problem since this tool is meant for development purposes, but needed to be called out.
