For example, do you want to make sure your customers read the product description before adding your product to your cart? Or perhaps you want the Add to Cart button to grab their attention by fading in a few moments after the page loads? The code to do this is pretty simple:
To hide the Add to Cart button for an entire shopping cart theme, edit the theme and add the code snippet to the Custom Header under the HTML Areas tab.
To hide the Add to Cart button for an individual product, edit the product and add the code snippet to the Long Description. Click the Source tab for the Long Description before pasting in the code.
