How to save custom style rule to LocalStorage?

Button works, but after refreshing the page, the rule is gone.

My code:

  // Create the <style> tag
  var style = document.createElement("style");
  // WebKit hack :(
  style.appendChild(document.createTextNode(""));
  // Add the <style> element to the page
  document.head.appendChild(style);
  return style.sheet;
})();


// Button
let spaces = document.getElementById("spaces"); 
spaces.onclick = () => {
  sheet.insertRule(".navbar {letter-spacing: 3px !important;}", 0);

};

You can do it like this:

localStorage.setItem("your item name or id goes here", "value goes here");

So for what you want it could be like this:

localStorage.setItem("size", "15px");
Then you have to get it when the window loads:

window.onload = function(){
var nav = document.getElementById(navbar);
var finalSize = localStorage.getItem('size');
nav.style.letterSpacing = finalSize;
}

Also, give your navbar or element and ID of "navbar". Also, there is no need to create a style tag. You can do that with style in javascript.

Shouldn't that be the normal behavior, refreshing the page should reset it to the initial state?

If you want to use LocalStorage for saving the style rules, you can

// Button
let spaces = document.getElementById("spaces"); 
spaces.onclick = () => {
  sheet.insertRule(".navbar {letter-spacing: 3px !important;}", 0);
  localStorage.setItem("addNavbarRule", true)
};

// on page load
window.onload = function(){
  if (localStorage.getItem("addNavbarRule")){
      sheet.insertRule(".navbar {letter-spacing: 3px !important;}", 0);
   }
}
