How to save CSS changes of Styles panel of Chrome Developer Tools?

Question

You can save your CSS changes from Chrome Dev Tools itself. Chrome now allows you to add local folders to your Workspace. After allowing Chrome access to the folder and adding the folder to the local workspace, you can map a web resource to a local resource.

• Navigate to the Sources panel of the Developer Tools, Right-click in the left panel (where the files are listed) and select Add Folder to Workspace. You can get to a stylesheet in the Sources panel quickly by clicking the stylesheet at the top-right of each CSS rule for a selected element in the Elements panel.

• After adding the folder, you'll have to give Chrome access to the folder.

• Next, you need to map the network resource to the local resource.

• After reloading the page, Chrome now loads the local resources for the mapped files. To make things simpler, Chrome only shows you the local resources (so you don't get confused on as to whether you are editing the local or the network resource). To save your changes, press CTRL + S when editing the file.

p.s.

You may have to open the mapped file(s) and start editing to get Chrome apply the local version (date 201604.12).

Starting in Chrome 65, Local Overrides is a new, lightweight way to do this. This is a different feature than Workspaces.

Set up Overrides

1. Go to Sources panel.
2. Go to Overrides tab.
3. Click Select Folder For Overrides.
4. Select which directory you want to save your changes to.
5. At the top of your viewport, click Allow to give DevTools read and write access to the directory.
6. Make your changes. In the GIF below, you can see that the background:rosybrown change persists across page loads.

How overrides work

When you make a change in DevTools, DevTools saves the change to a modified copy of the file on your computer. When you reload the page, DevTools serves the modified file, rather than the network resource.

The difference between overrides and workspaces

Workspaces is designed to let you use DevTools as your IDE. It maps your repository code to the network code, using source maps. The real benefit is if you're minifying your code, or using code that needs to get transpiled, like SCSS, then the changes you make in DevTools (usually) get mapped back into your original source code. Overrides, on the other hand, let you modify and save any file on the web. It's a good solution if you just want to quickly experiment with changes, and save those changes across page loads.

New versions of Chrome have a feature called workspaces which addresses this issue. You can define which paths on your webserver correspond to which paths on your system, then edit and save with just ctrl-s.

I know it is an old post, but I save it this way :

1. Go to Sources pane.
2. Click Show Navigator (to show the navigator pane on left).
3. Click the CSS file you want. (It will open in the editor, with all changes you made)
4. Right click on editor and Save your changes.

You can also see Local Modifications to see your revisions, very interesting feature. Also work with scripts.

You're looking in the wrong section of "Resources".

It's not under "Local Storage", it's under "Frames":

The above screenshot shows a diff of the original styles against the new modifications made in the devtools. You can right-click the item in the left pane and save it back to disk.
