Looking for help - Prestige Theme Product Customization with personal note

Hi everybody,

I am new to Shopify and need some help in adjusting my theme to the requirements of my products.

I use the prestige theme and would like to add a text field to some of my products for a personal note. Ideally below the quantify selector and above the shopping cart button.

In addition to that this text field should be a required field and if the customer does not add it - he won’t be able to add the product to the cart and a note popes up to remind him to fill out the text field

Since prestige does not offer a note field I assume - this needs to be added via CSS. I found a video outlining exactly what I need however its just for the dawn theme:/.

Would really appreciate some help since this is the only thing that’s left to do before I can go live!

Thanks!

It should work for prestige theme too. Try doing what the person did in the video and if it doesnt work you can lemme know then we see whats happening
