What I'm trying to do is when the checkbox is checked, change the background color of the div, and when it's unchecked, remove the background color. How can I do this using jquery?

<div class="checkbox-container">
    <input type="checkbox" class ="checkbox-border" id="personal-info-checkbox">
      <label for="personal-info-checkbox"> Mark as reviewed and acknowledged
      </label>
 </div>

using parent selector and .removeclass I do not know how to select my div and turn the color off and on using jquery.

• 2 What have you tried, in order to solve this yourself? Where's your (relevant) "minimal reproducible example" code? What went wrong - and in what way - with that code, were there any errors reported? – David Thomas Commented Dec 7, 2022 at 16:45
• To give you a direction to start looking at, you need to set an event listener on your checkbox and, since using jQuery, you can use the toggleClass() method on your container element: api.jquery./toggleclass – Jeremy Harris Commented Dec 7, 2022 at 16:49

You don't need jQuery for this
You can do this only with css.

    .checkbox-container:has(input:checked) {
    background-color: red;
}

:has pseudo class is supported in chromium, safari.
For firefox, need to enable flag. know more at mdn ::has pseudo class

Add a change event listener to the input that sets its closest parent div's background color based on whether it is checked:

$('input[type="checkbox"]').change(function(){
  $(this).closest('div').css('background-color', this.checked ? 'green' : 'white')
})

<script src="https://cdnjs.cloudflare./ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="checkbox-container">
    <input type="checkbox" class ="checkbox-border" id="personal-info-checkbox">
      <label for="personal-info-checkbox"> Mark as reviewed and acknowledged
      </label>
 </div>

Here's an example of how you can do this

$(function() {
  $("input[type=checkbox]").click( () => {
    $("div").toggleClass("background");
  })
});

.background {
  background: blue;
}

<script src="https://cdnjs.cloudflare./ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div style="height:4em;">
Change colors<input type="checkbox" />
</div>

There are a number of ways to do this:

1. CSS (with limited, as of writing, browser support),
2. jQuery (among other libraries), and
3. native JavaScript.

The below example has explanatory ments in the code:

// using jQuery, we select the relevant element via its class, and use the on()
// method to bind the anonymous function as the event-handler for the 'change'
// event:
$('.checkbox-container.with-jQuery').on('change', function(){
  // here we find the <input> element descendant with find(), and then use the
  // is() method to test that element to see if it matches the :checked pseudo-
  // class; this returns a Boolean true/false which is cached in the 'checked'
  // variable:
    let checked = $(this).find('input').is(':checked');
  
  // here we use toggleClass() to toggle the 'checked' class-name on the element,
  // and use the 'checked' variable to ascertain whether the class should be
  // added/retained (if the Boolean is true) or removed/not-added (if the Boolean
  // is false):
    $(this).toggleClass('checked', checked);
});


// using JavaScript we use document.querySelector to retrieve the element
// with the listed classes; and use EventTarget.addEventListener() to bind the
// anonymous Arrow function as the event-handler for the 'change' event:
document.querySelector('.with-JavaScript.checkbox-container').addEventListener('change',(evt)=>{
  // we cache a reference to the current element (the <div>):
    let current = evt.currentTarget,
      // we find the <input> descendant, and access its checked property to
      // obtain a Boolean true (if checked) or false (if not-checked) and
      // store that Boolean in the 'checked' variable:
        checked = current.querySelector('input').checked;
  // here we use Element.classList.add() to add the 'active' class-name,
  // with the checked variable to determine if it should be added/retained
  // (if true) or removed/not-added (if false):
    current.classList.add('active', checked);
});

:root {
  --checkedColor: lime;
}

/* here we select the element via classes, and use :has()
   to check if it has a descendant element which matches
   the enclosed selector: */
.with-CSS.checkbox-container:has(input:checked) {
  /* if so, we set the --checkedColor custom property
     as the background-color of the element: */
  background-color: var(--checkedColor);
}

.with-jQuery.checkbox-container.checked {
  background-color: var(--checkedColor);
}

.with-JavaScript.checkbox-container.active {
  background-color: var(--checkedColor);
}

<!-- each wrapper <div> has a 'with-...' class applied in order to identify which
     approach is being taken: -->
<div class="checkbox-container with-CSS">
  <!-- an id must be unique, to that end - because there are three checkboxes in
       this example - the id has been modified, as has the corresponding <label>
       element's 'for' attribute: -->
  <input type="checkbox" class="checkbox-border" id="personal-info-checkbox1">
  <label for="personal-info-checkbox1"> Mark as reviewed and acknowledged
  </label>
</div>

<div class="checkbox-container with-jQuery">
  <input type="checkbox" class="checkbox-border" id="personal-info-checkbox2">
  <label for="personal-info-checkbox2"> Mark as reviewed and acknowledged
  </label>
</div>

<div class="checkbox-container with-JavaScript">
  <input type="checkbox" class="checkbox-border" id="personal-info-checkbox3">
  <label for="personal-info-checkbox3"> Mark as reviewed and acknowledged
  </label>
</div>
