VS Code - Elements for Microsoft Edge (Chromium)

Show the browser's Elements tool inside the VSCode editor and use it to fix styling, layout, and css issues with your site.

A VS Code extension that allows you to use the browser's Elements tool from within the editor. The Elements tool will connect to an instance of Microsoft Edge giving you the ability to see the runtime HTML structure, alter layout, and fix styling issues. All without leaving VS Code.

Note: This extension only supports Microsoft Edge (Chromium)

Supported Features

• Debug configurations for launching Microsoft Edge browser in remote-debugging mode and auto attaching the tools
• Side Bar view for listing all the debuggable targets, including tabs, extensions, service workers, etc.
• Fully featured Elements tool with views for HTML, CSS, Accessibility and more
• Screen-casting feature to allow you to see your page without leaving VSCode

Using the Extension

Getting Started

For use inside VS Code:

1. Install any channel (canary/dev/etc.) of Microsoft Edge (Chromium)
2. Install the extension
3. Open the folder containing the project you want to work on.

Using the tools

The extension operates in two modes - it can launch an instance of Microsoft Edge navigated to your app, or it can attach to a running instance of Microsoft Edge. Both modes requires you to be serving your web application from local web server, which is started from either a VS Code task or from your command-line. Using the url parameter you simply tell VS Code which URL to either open or launch in the browser.

Debug Configuration

You can launch the Elements for Microsoft Edge extension like you would a debugger, by using a launch.json config file. However, Elements for Microsoft Edge isn't a debugger and so any breakpoints set in VS Code won't be hit, you can of course use a different debug extension instead and attach the Elements for Microsoft Edge extension once debugging has started.

To add a new debug configuration, in your launch.json add a new debug config with the following parameters:

• type - The name of the debugger which must be vscode-edge-devtools.debug. Required.
• request - launch to open a new browser tab or attach to connect to an existing tab. Required.
• name - A friendly name to show in the VS Code UI. Required.
• url - The url for the new tab or of the existing tab. Optional.
• file - The local file path for the new tab or of the existing tab. Optional.
