Edit web page source code directly in Chrome browser, saying goodbye to the tedious editing - refresh loop! This article will guide you how to use Chrome developer tools to edit HTML, CSS and JavaScript files directly and iterate in development quickly.

The daily workflow of web developers is usually: write HTML, CSS and JavaScript code in the editor, then open the page in the browser, use the developer tools to debug after discovering problems, modify the code and copy it back to the editor, and then Reloading the page… While tools like hot reloading simplify the process, many developers still switch between developer tools and editors. In fact, Chrome allows you to open and edit source files directly in the browser. The modified content will be automatically saved to the file system and updated to the editor (assuming that the editor supports automatic refresh of file changes).

Step 1: Start the developer tool

Open Chrome, load the page on the local file system or server, and then open the developer tools through the More Tools menu, or press F12 or Ctrl/Cmd Shift I (depending on your operating system). Switch to the Sources tab to view File Explorer:

You can open and edit CSS and JavaScript files directly in this view, but be aware that these changes will be lost after refreshing the page.

Step 2: Associate the workspace folder

Click on the "Filessystem" tab, and then click "Add folder to workspace". You will be prompted to select a working folder and you will be asked to allow Chrome to access the folder. Explorer will display the files on the system, you can click to open:

Step 3: Edit and save the code

Now you can edit the code directly. Unsaved edits are marked with an asterisk (*) on the file label.

CSS changes are updated immediately, but for HTML and JavaScript, you usually need to press Ctrl/Cmd S to save the file to the file system and refresh the browser to see the effect.

You can also right-click the file label and select "Save As..." to save a copy of the file to another location.

Step 4: View and Undo Changes

To view the changes, right-click the file label and select "Local modifications..." from the context menu:

will display a view similar to diff. The arrow icon in the lower left corner of the pane will undo all changes and restore the file to its original state.

Chrome's developer tool is not a complete replacement for your commonly used code editor, but it is still a very useful tool when making quick changes or working on other computers where the editor is not installed.
