title: When should I use CSSStylesheet.insertRule
body: <p>When would it be a good time to use the <a href="https://developer.mozilla.org/en-US/docs/Web/API/CSSStyleSheet/insertRule" rel="nofollow noreferrer">CSSStylesheet.insertRule</a> over using the <a href="https://www.w3schools.com/js/js_htmldom_css.asp" rel="nofollow noreferrer">style object in the DOM elements</a>?</p>
  
  <p>I guess i'm wondering about the performance differences between the two</p>
