CSS rule that could break your Sitecore 8.2 Experience Editor

Today when I was using the Experience Editor on my Sitecore 8.2 Update 3 site and I found that nothing of the following works:

  • Assigning renderings to placeholders
  • Some of the buttons in the ribbon does nothing when clicked
  • Etc, etc
I have checked Chrome console logs... no javascript errors, no 500 or 404 under network tab. Checked Sitecore logs... no exceptions were thrown.

What could it be? I have started scratching my head...

Checking here, checking there, asking my colleague and starting removing whatever is on the page one by one.

At the end we figured out that there is one CSS rule:

body > iframe { display: none;}

We removed it and the Experience Editor starts working again. Why?

This rule effectively hide any iframes that are directly under the body tag, whether they are created dynamically by external javascripts or by yourself. Unfortunately Sitecore Experience Editor also has an iframe directly under body for serving the modal dialog. Therefore when this rule is present, the functionality behind the buttons (that pop up a modal dialog) actually works but the dialog is not showing.

We have only tested this on Sitecore 8.2 so not sure if it affects earlier 8.x versions. The iframe used by Sitecore looks like:

  <iframe allowtransparency="true" 

So once we know this, we can get around this by excluding this from the CSS rule:

body > iframe:not(#jqueryModalDialogsFrame) { display: none;}
Hopefully this helps!

Sitecore Habitat and Fortis

If you don't know what is Habitat yet, please have a look at its Github:

By default, Habitat does not use any mapping tool (such as Glass Mapper, Fortis, or the emerging Synthesis) so keep it simple however it does not mean that Sitecore doesn't prefer using one of those.

I have created a fork of the original Habitat solution and made it Fortis-enabled. A Fortis.Foundation module is added to the foundation layer which is responsible for the registration of Fortis and the code-generation of the Fortis model based on Unicorn.

You can find the repo here:

[Updated 2017-05-03] I have also updated this Habitat to support Sitecore 8.2 Update 3, check if required.

Happy Habitating!
