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)
- 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
For use inside VS Code:
- Install any channel (Canary/Dev/etc.) of Microsoft Edge (Chromium).
- Install the extension Elements for Microsoft Edge.
- Open the folder containing the project you want to work on.
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.
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
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.
"name": "Launch Microsoft Edge and open the Elements tool",
"name": "Attach to Microsoft Edge and open the Elements tool",
Other optional launch config fields
browserPath: The full path to the browser executable that will be launched. If not specified the most stable channel of Microsoft Edge (Chromium) will be launched from the default install location instead.
hostname: By default the extension searches for debuggable instances using
localhost. If you are hosting your web app on a remote machine you can specify the hostname using this setting.
port: By default the extension will set the remote-debugging-port to
9222. Use this option to specify a different port on which to connect.
userDataDir: Normally, if Microsoft Edge is already running when you start debugging with a launch config, then the new instance won't start in remote debugging mode. So by default, the extension launches Microsoft Edge with a separate user profile in a temp folder. Use this option to set a different path to use, or set to false to launch with your default user profile instead.
useHttps: By default the extension will search for attachable instances using the
http protocol. Set this to true if you are hosting your web app over
