By clicking on the tag <a> is displayed a modal. How can I make so that when the person enters the site, the modal appear without the click?

.modalDialog {
  position: fixed;
  font-family: Arial, Helvetica, sans-serif;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  background: rgba(0, 0, 0, 0.8);
  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: -moz-linear-gradient(#fff, #999);
  background: -webkit-linear-gradient(#fff, #999);
  background: -o-linear-gradient(#fff, #999);
}

.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>
    <h2>Popup</h2>
    <p>Isto é uma popup toda bonitinha a funcionar apenas com CSS3.</p>
  </div>
</div>

I suggested an issue in the question, partly changing pop up for modal (which is the most commonly used term for that "component").

You can open the modal using the event Domcontentloaded to perform a certain action when the HTML is loaded, for example by simulating the click in the link:

let open = document.getElementsByTagName('a')[0];

document.addEventListener('DOMContentLoaded', function() {
  open.click();
});

.modalDialog {
  position: fixed;
  font-family: Arial, Helvetica, sans-serif;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  background: rgba(0, 0, 0, 0.8);
  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: -moz-linear-gradient(#fff, #999);
  background: -webkit-linear-gradient(#fff, #999);
  background: -o-linear-gradient(#fff, #999);
}

.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>
    <h2>Popup</h2>
    <p>Isto é uma popup toda bonitinha a funcionar apenas com CSS3.</p>
  </div>
</div>

Now if you want to open the modal without the tag a in the Html markup, you can create the tag and trigger the click action:

let tagA = document.createElement('a');
let hrf = document.createAttribute('href');
hrf.value = '#openModal';
tagA.setAttributeNode(hrf);

document.addEventListener('DOMContentLoaded', function() {
  tagA.click();
});

.modalDialog {
  position: fixed;
  font-family: Arial, Helvetica, sans-serif;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  background: rgba(0, 0, 0, 0.8);
  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: -moz-linear-gradient(#fff, #999);
  background: -webkit-linear-gradient(#fff, #999);
  background: -o-linear-gradient(#fff, #999);
}

.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;
}

As your modal is opened according to what is in the URL, you can simply use the function window.onload= function(){} javascript, along with the window.location and window.location.href + idModal, ie in only 3 lines you can, example:

window.onload = function(){
   window.location = window.location.href +'#openModal'
}

.modalDialog {
  position: fixed;
  font-family: Arial, Helvetica, sans-serif;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  background: rgba(0, 0, 0, 0.8);
  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: -moz-linear-gradient(#fff, #999);
  background: -webkit-linear-gradient(#fff, #999);
  background: -o-linear-gradient(#fff, #999);
}

.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>
    <h2>Popup</h2>
    <p>Isto é uma popup toda bonitinha a funcionar apenas com CSS3.</p>
  </div>
</div>
