Is there a purely HTML5 alternative to JS's Alert Box? I have never dabbled with JS or other scripts/codes, i'm fortable with HTML5 and CSS3 only, (i'm really into semantics :) )

No worries if not, more curious than in need.

Thanks! Jess

• Are you looking something like modals? – laaposto Commented Feb 5, 2014 at 14:30
• 3 html5 does not exactly replace javascript. – njzk2 Commented Feb 5, 2014 at 14:30
• 1 There are alert analogs prising HTML elements manipulated by JavaScript but nothing directly equivalent. JavaScript and HTML fulfil different roles. – Alex K. Commented Feb 5, 2014 at 14:31
• There is no way to exactly replicate the behaviour of an alert box, not even with JavaScript. – Pekka Commented Feb 5, 2014 at 14:35
• You could do a popup of sorts in a container in HTML which has a css "hidden" property and use some very light JS in order to hide and show it. Would that suit your needs? – aaron-bond Commented Feb 5, 2014 at 14:36

HTML5 is a platform and brand. It include many javascript API, CSS3 modules and etc. Try to use :target CSS3 example of alert, for example. It use top features of CSS3.

Code from pen:

HTML

<div class="wrap">
  <h1>Modal - Pure CSS (no Javascript)</h1>
  <p>Example of modal in CSS only, here I use the pseudo selector ":target" and no javascript for modal action.</p>
  <p>This works in IE9+ and all modern browsers.</p>
  <p>View <a href="http://www.felipefialho./css-ponents/">Pure CSS Components</a> project.</p>
  <hr />
  <a href="#modal-one" class="btn btn-big">Modal!</a>
</div>

<!-- Modal -->
<div class="modal" id="modal-one" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-header">
      <h2>Modal in CSS?</h2>
      <a href="#" class="btn-close" aria-hidden="true">×</a>
    </div>
    <div class="modal-body">
      <p>One modal example here! :D</p>
    </div>
    <div class="modal-footer">
      <a href="#" class="btn">Nice!</a>
    </div>
  </div>
</div>
<!-- /Modal -->

}
.modal-footer {
  border-top: #eeeeee solid 1px;
  text-align: right;
}

EDIT:

Chrome Canary 37+ has dialog element. More info in code example. The main profit from it is show, close and showModal methods and ::backdrop css selector for background.

No, there is no way to display a popup that doesn't use any JavaScript (At least, nothing that's practical). This is because you need some sort of code to manage the popup's message, or even to make the popup appear.

CSS-only examples rely on the user clicking something for the popup to show.

You can have a look at jQueryUI's modal. But that's a bination of html / css / js

The best option would be to write one from scratch if you don't want to use alert(). There are plenty of libraries that can do it for you, look around a bit and you'll find at least one.
