I've created CSS-only popup which is working only by clicking on the link/button. I want to show this popup automatically on page load. Also, how this popup can be opened without clicking on the link/button i.e. By using Javascript/jQuery.

Fiddle

.modalDialog {
  position: fixed;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  z-index: 99999;
  opacity: 0;
  -webkit-transition: opacity 400ms ease-in;
  -moz-transition: opacity 400ms ease-in;
  transition: opacity 400ms ease-in;
  pointer-events: none;
}
.modalDialog:target {
  opacity: 1;
  pointer-events: auto;
}
.modalDialog > div {
  width: 400px;
  position: relative;
  margin: 10% auto;
  padding: 5px 20px 13px 20px;
  border-radius: 10px;
  background: #fff;
  background: #339999;
}
.close {
  background: #606061;
  color: #FFFFFF;
  line-height: 25px;
  position: absolute;
  right: -12px;
  text-align: center;
  top: -10px;
  width: 24px;

  -webkit-box-shadow: 1px 1px 3px #000;
  box-shadow: 1px 1px 3px #000;
}
.close:hover {
  background: #00d9ff;
}

<a href="#openModal">Open Modal</a>

<div id="openModal" class="modalDialog">
  <div>
    <a href="#close" title="Close" class="close">X</a>

• Show us what you've tried (with jQuery) – Popnoodles Commented Aug 26, 2015 at 8:56
• You talk about your code actually triggering the pop up on click, may we see what you have written in JQuery so far ? – Anwar Commented Aug 26, 2015 at 8:56

There is no need of jQuery, you can acplish this using Vanilla Javascript. To open the popup automatically on page load, set the hash to the id of popup.

Demo

function openPopup() {
  window.location.hash = 'openModal';
}

window.onload = openPopup;

.modalDialog {
  position: fixed;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  z-index: 99999;
  opacity: 0;
  -webkit-transition: opacity 400ms ease-in;
  -moz-transition: opacity 400ms ease-in;
  transition: opacity 400ms ease-in;
  pointer-events: none;
}
.modalDialog:target {
  opacity: 1;
  pointer-events: auto;
}
.modalDialog > div {
  width: 400px;
  position: relative;
  margin: 10% auto;
  padding: 5px 20px 13px 20px;
  border-radius: 10px;
  background: #fff;
  background: #339999;
}
.close {
  background: #606061;
  color: #FFFFFF;
  line-height: 25px;
  position: absolute;
  right: -12px;
  text-align: center;
  top: -10px;
  width: 24px;
  text-decoration: none;
  font-weight: bold;
  -webkit-border-radius: 12px;
  -moz-border-radius: 12px;
  border-radius: 12px;
  -moz-box-shadow: 1px 1px 3px #000;
  -webkit-box-shadow: 1px 1px 3px #000;
  box-shadow: 1px 1px 3px #000;
}
.close:hover {
  background: #00d9ff;
}

<a href="#openModal">Open Modal</a>

<div id="openModal" class="modalDialog">
  <div>
    <a href="#close" title="Close" class="close">X</a>

    <p style="color:white">This is a sample modal box that can be created using the powers of CSS3.</p>

  </div>
</div>

<button onclick="openPopup()">Open popup by Javascript</button>

You can also create a generic function to open the popups:

function openPopup(popupId) {
    window.location.hash = popupId;
}

As you are just hiding the popup using css opacity you can just use jquery on page load to show the popup or fade it in if you want to add a bit of animation.

Also its probably a good idea to set the display of the popup to none in css or you may run into problems at a later date. You could do something like:

.modalDialog {
  //added display none on element
  display:none;
  position: fixed;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  z-index: 99999;
  //opacity: 0;
  -webkit-transition: opacity 400ms ease-in;
  -moz-transition: opacity 400ms ease-in;
  transition: opacity 400ms ease-in;
  pointer-events: none;
}

$(document).ready(function() {
  //Use jQuery to show the popup
  $('.modalDialog').show();
  //Alternativly use jQuery to fadeIn the popup
  $('.modalDialog').fadeIn()
})

Final updated code: https://jsfiddle/q4n7p0jx/1/

Just need to trigger click on the link when the page loads.

$(document).ready(function() {
  console.log($('a[href="#openModal"]')[0]);
  $('a[href="#openModal"]')[0].click();
})

.modalDialog {
  position: fixed;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  z-index: 99999;
  opacity: 0;
  -webkit-transition: opacity 400ms ease-in;
  -moz-transition: opacity 400ms ease-in;
  transition: opacity 400ms ease-in;
  pointer-events: none;
}
.modalDialog:target {
  opacity: 1;
  pointer-events: auto;
}
.modalDialog > div {
  width: 400px;
  position: relative;
  margin: 10% auto;
  padding: 5px 20px 13px 20px;
  border-radius: 10px;
  background: #fff;
  background: #339999;
}
.close {
  background: #606061;
  color: #FFFFFF;
  line-height: 25px;
  position: absolute;
  right: -12px;
  text-align: center;
  top: -10px;
  width: 24px;
  text-decoration: none;
  font-weight: bold;
  -webkit-border-radius: 12px;
  -moz-border-radius: 12px;
  border-radius: 12px;
  -moz-box-shadow: 1px 1px 3px #000;
  -webkit-box-shadow: 1px 1px 3px #000;
  box-shadow: 1px 1px 3px #000;
}
.close:hover {
  background: #00d9ff;
}

<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.0/jquery.min.js"></script>

<div id="openModal" class="modalDialog">
