Question

I have a CSS class Modal which is absolutely positioned, z-indexed above it’s parent, and nicely positioned with JQuery. I want to add a caret image (^) to the top of the modal box and was looking at using the :before CSS pseudo selector to do this cleanly.

The image needs to be absolutely positioned and z-indexed above the modal, but I haven’t found any way to add the appropriate class to the image in the content attribute:

.Modal:before{
  content:url('blackCarrot.png') /* with class ModalCarrot ??*/
}

.ModalCarrot{
   position:absolute;
   left:50%;
   margin-left:-8px;
   top:-16px;
}

Second best option- can I add the styles inline in the content attribute?

http://caniuse.com/#search=::after

::after and ::before with content are better to use as they’re supported in every major browser other than Internet Explorer at least 5 versions back. Internet Explorer has complete support in version 9+ and partial support in version 8.

Is this what you’re looking for?

.Modal::after{
  content:url('blackCarrot.png'); /* with class ModalCarrot ??*/
  position:relative; /*or absolute*/
  z-index:100000; /*a number that's more than the modal box*/
  left:-50px;
  top:10px;
}

.ModalCarrot{
   position:absolute;
   left:50%;
   margin-left:-8px;
   top:-16px;
}

If not, can you explain a little better?

or you could use jQuery, like Joshua said:

$(".Modal").before("<img src='blackCarrot.png' class='ModalCarrot' />");
