Hiding or changing discount code in shopping cart
When the Discounts module is active, a text "Enter discount code" appears in the shopping cart below the product list. This script hides or changes this text.

1. Navigate to Management > CMS
2. Scroll down and edit the page Shopping cart (or basket or bag)
3. Click on the Edit HTML icon in the footer

To hide the text, add this CSS code:

<style>
#enter_couponcode { display: none; }
</style>

To change the text, add this Javascript code:

<script>
document.getElementById('enter_couponcode').firstChild.firstChild.innerText = 'Enter your text here';
</script>
