Edit the header tags

I need to install a facebook pixel on my site but I cannot find how to edit the header tag if not by publishing the site and then editing it manually.

thoughts?

@ayahni, Yes the best way is to place the code in an “Embed” element and then go to your Arrange tab/Visibility: Show on all Pages to make the Pixel common to all pages. Also don’t forget to “generate meta data for social sharing” by going into Settings/Sharing.

Maybe @duncan this could be a great addition to Sparkle as more and more users are using Facebook to advertise?
