Q:

How can you make an HTML element 'float' without affecting any other elements? 

I am designing a product card, and I want to have the delete button be a round button with the X in the upper right corner of the product's photo. 
I usually would use position absolute to achieve this floating effect, but considering this is an element that will be dynamically created for different products, I need some way of styling it that is relative to the parent element, as I don't know the position of each product card.  I don't think I can use position absolute, as it would be a different position for every product card. 
Any Ideas? 
HTML
<div class="cart-card">
  <span class="delete-button">
  <i class="fas fa-times"></i>
  </span>
  <div class="cart-img-cont">
    <img src="" alt="" class="cart-img" />
  </div>
  <p class="cart-card-product-name h-font">Product Name</p>
  <div class="cart-card-price">
    <p class="cart-price">$15.00</p>
    <p class="cart-merchant">
      <span class="cart-from">From</span> Merchant Name
    </p>
  </div>
  <div class="cart-card-qty-cont"></div>
  <div class="cart-opt-cont">

    <select name="" id="" class="opt-select">
      <option value="#">Option</option>
    </select>
  </div>
