html - All css accordion divs open by default (no jquery)

Question

I'm using this:

jsfiddle.net/wromLbq5

And am hoping to have the ability to have multiple accordion sections open at once, and on page load. By this I mean, when one opens, I don't want the other to close. Is this possible? Without javascript as well.

(Ignore all the sub accordions too- I only need one layer)

HTML

<ul class="accordion">

      <li><a href="#three"><em>03</em>Options<span>27</span></a></li>
    </ul>
  </li>

I'm trying to avoid any java script. Is this possible?

Answer 1

No this is not possible with only css, because your example uses the CSS3 :target selector. When you click on another item the target changes.

You cannot set state with css but you can style it. If you would like to keep each section open after clicking you would have to use javascript, but you don't need jQuery

If you would like to use javascript, this mimics the css as closely as possible while allowing the accordions to stay open. To close the accordion simply click on the title again.

var lists = document.querySelectorAll('.accordion > li > a'); // get list title links
for (var i = 0; i < lists.length; i++) { // for each list title link
  lists[i].href = "javascript:void()"; // stop the page from jumping
  lists[i].onclick = function(e) { // when you click the link
    var items = e.target.parentNode.querySelectorAll('li'); // get all list items that are siblings of the clicked link
    for (var x = 0; x < items.length; x++) { // for each list item
      if (items[x].style.height != '33px') { // if its not open
        items[x].style.height = '33px'; // open it
      } else { // otherwise
        items[x].style.height = '0px'; // close it
      }
    }
  };
}

Wrap this in a script tag then either drop it in at the bottom of the body, or wrap it in document.onload = function() { /* Script Here */ }

(Demo)

Note while any style with the :target selector will cease to have effect, you should leave them in the css as a fallback in case the user has javascript disabled.
