<div class="date" k-show="[[coffeeshop.blogpost.blogimage.url == null || coffeeshop.blogpost.blogimage.url == '']]"> <img src="/images/coffee_cup.png"> </div>
This will only show the specified image if there is no image in the update on k-admin/manage or if the url retured by kitsune backend is null.
When kitsune compiles your HTML page, if the condition given with the k-show tag is true, only then shows that HTML tag in its children. Giving you website a seamless appearance :D

<div k-hide="[[coffeeshop.blogpost.length() > 0]]"> <p>Keep watching this space for information about our awesome products.</p> </div>
This will show the message if there are no products available on k-admin.
You can use k-hide and k-show together to give conditions like: hide the section if no items are available and show some default message/image in its place.
When the client adds the items on k-admin, then the default message disappear and the item(s) will come up.
