Permanently change selected text background color

Issue

How can I permanently change the background color of DIV text when I select it ? What I am trying to achieve is a highlight effect like this:

Anyone can instruct me how to accomplish this with javascript?

I appreciate your help a lot.

EDIT: I need my text to stay highlighted and highlight multiple texts without losing the highlight of the previous ones.

Solution

You need to add event listener in javascript and when a text is selected at that time need to change the color like below

function logSelection(event) {
  // Get Selection
  sel = window.getSelection();
  if (sel.rangeCount && sel.getRangeAt) {
    range = sel.getRangeAt(0);
  }
  // Set design mode to on
  document.designMode = "on";
  if (range) {
    sel.removeAllRanges();
    sel.addRange(range);
  }
  // Colorize text
  document.execCommand("ForeColor", false, "red");
  // Set design mode to off
  document.designMode = "off";
}

const input = document.querySelector('input');
input.addEventListener('select', logSelection);
