Converts :hover CSS to :active CSS on mobile devices

/**

function hoverTouchUnstick() {
  // Check if the device supports touch events
  if('ontouchstart' in document.documentElement) {
    // Loop through each stylesheet
    for(var sheetI = document.styleSheets.length - 1; sheetI >= 0; sheetI--) {
      var sheet = document.styleSheets[sheetI];
      // Verify if cssRules exists in sheet
      if(sheet.cssRules) {
        // Loop through each rule in sheet
        for(var ruleI = sheet.cssRules.length - 1; ruleI >= 0; ruleI--) {
          var rule = sheet.cssRules[ruleI];
          // Verify rule has selector text
          if(rule.selectorText) {
            // Replace hover psuedo-class with active psuedo-class
            rule.selectorText = rule.selectorText.replace(":hover", ":active");
          }
        }
      }
    }
  }
}

I found I had more success using a greedy regex on line 25

rule.selectorText = rule.selectorText.replace(/\:hover/ig, ":active");
