To see how your webpage renders and behaves when a browser doesn't have JavaScript support, temporarily turn off JavaScript.
To turn off JavaScript:
To open DevTools, right-click the webpage, and then select Inspect. Or, press Ctrl+Shift+I (Windows, Linux) or Command+Option+I (macOS). DevTools opens.
Press Ctrl+Shift+P (Windows, Linux) or Command+Shift+P (macOS) to open the Command Menu:
Start typing javascript, select Disable JavaScript [Debugger], and then press Enter:
The yellow triangular warning icon in the Sources tab indicates that JavaScript is disabled:
JavaScript remains disabled in the tab for as long as you have DevTools open.
To check how the page behaves without JavaScript, refresh the page.
To re-enable JavaScript:
Press Ctrl+Shift+P (Windows, Linux) or Command+Shift+P (macOS) to open the Command Menu.
Select the Enable JavaScript [Debugger] command, and then press Enter.
This module covers various concepts on the topic of accessibility and how to add it to your web applications during web development. You will learn the importance of using HTML tags properly to describe information, and various improvements you can make to your sites.
Snippets are small scripts that you can author and run within the Sources tool of Microsoft Edge DevTools. You can access and run resources from any webpage. When you run a Snippet, it runs from the context of the currently open webpage.
Use the Sources tool to view, modify, and debug JavaScript that's returned by the server, and to inspect the resources that make up the current webpage. To use the Sources tool as a development environment, add source files to a Workspace.
