How to make an added note a required field on Shopify?

[mj246]

I want customers to enter a note before checking out at our store. I have the note customized but want it to be/say “required field” before they check out. How can I accomplish this?

Add the required attribute to the html input.

Thought without also writing validation rules this can just mean people have to enter a single character to proceed.

simply add ‘required’ in the textarea tag.

e.g. <textarea required class=“text-area field__input” name=“note” form=“cart” id=“Cart-note” placeholder=“{{ ‘sections.cart.note’ | t }}” >{{ cart.note }}
