Hiii

I added rich text in bw subtotal and tax note and when I add product in cart page and increase the quantity or even add a new product then the rich text get mixed with subtotal and tax note. Please check the screenshot below

I added this code to add rich text in theme.liquid -

<script>
let totals = document.querySelector('.totals');
if(totals) {
totals.insertAdjacentHTML('afterend', '<br><div class="custom-richtext">Incl. of all taxes and costs</div>');
}
</script>
