I have worked on several preview features. I first opted for an overlay with an iframe. This provided the advantage of making a quick glance at the information being presented without having to change page. 

However, when we then tried it with the preview loading as a new page in the current tab (not opening a new window and removing the iframe altogether) this allowed for us to also use the same page template we had created for viewing the posted item and provided a better experience to the user.

Once the preview was accepted we directed the user back to their home page. Or if it was rejected they could go back to edit it. The response we had from users was much better with this approach as it meant they could look at the content on different devices more easily, could scroll just with the page scroll bar and meant that the build was actually quicker as we were using similar templates. I would encourage this approach over the use of iframes but speak with your users and see what they think.

Is it better to put "Preview" on an iFrame with a specific height or just show it in full?
I bought some juniper extract for making bath stuff, and it doesn't seem to be very effective for this purpose. I have used juniper berries before, so I thought I might be able to use the extract for cooking or baking. I have not been able to find any recipes online. 

Is juniper extract ok to eat? What types of applications would it be good for, I assume whole berries is much better choice for marinades. Would it have the same uses as orange or peppermint extract?
