title: Can I make a html-website function as a background-program?
body: <p>I have been working on a html-website lately. The website is a web-app made to measure time spent on a project and to map your efficiency per hour of the day.</p>
  
  <p>I have tested this website while looking at the website, and it worked fine. It is that I have just recently added a part where it will map your time over the day, and since I had to wait for 5 minutes while the clock was passing a 5 minute treshhold, I figured that it would be efficient to do some other things while letting the clock do its thing.</p>
  
  <p>Unfortunately I was kind of shocked to see that the clock had not changed even a millisecond, and that has to be because the js-interval was not continued when viewing a different chrome tab. Once I opened the clock it continued where it was left once I switched tabs.</p>
  
  <p><strong>Now my question is:</strong>
  Is there a way to let the HTML-website run in the background, just like a background-application, so you can do other tasks while the website will continue it's interval?</p>
