I have downloaded the code posted on this web site to see if that would work…..it does not (‘depot_n’).
Adding a product to the cart results in the cart briefly being displayed (with no HTML)…more like a stutter step down. Then after the specified number of seconds in the jQuery slide function (e.g. 1,000), the HTML pops into position. No sliding effect.
Something to note. The book uses a condition testing the number of ‘tr’ elements. If there is 1 ‘tr’ element then the cart should be displayed. This is flawed. An empty cart will have 1 tr element (for the total price). A cart with 1 line item will therefore have 2 ‘tr’ elements.
