title: How to use multiple languages in a single file in Visual Studio Code
body: <p>I am working on HTML file that has in-line JavaScript and CSS.  However, Visual Studio Code only provides IntelliSense for one language at a time: HTML IntelliSense only if I select HTML, JavaScript IntelliSense only if I set the file to be interpreted as JavaScript, etc.</p>
  
  <p>I want to know, is it possible to see IntelliSense for JavaScript, CSS, and HTML at the same time instead of needing to switch between them?</p>
