Issue with Cart Items Container's Scroll Behavior on Mobile Devices

Exploring a web layout where the .cart-items-container needs to occupy the remaining space above the .cart-rest-details section. The .cart-items-container should be scrollable if it overflows while the .cart-rest-details remains fixed at the bottom of the viewport. However, facing challenges with the layout specifically on mobile devices.

Providing my codebase below:

.cart-container {
  display: flex;
  flex-direction: column;
  gap: 16px;
  width: 100%;
  height: 100vh;
}

.cart-items-container {
  display: flex;
  flex-direction: column;
}

.cart-items {
  padding: 8px;
  max-height: 300px;
  overflow: auto;
  background-color: #EEEEEE;
  border: 2px solid orange
}

.cart-rest-details {
  display: flex;
  flex-direction: column;
  gap: 4px;
  width: 90%;
  padding: 5%;
  background-color: dodgerblue;
  color: white;
}

@media screen and (max-width: 768px) {
  .cart-items-container {
    flex-grow: 1;
  }

  .cart-items {
    flex-grow: 1;
    max-height: none;
  }
}

Answer №1

By adding the CSS rule resize: both to your .cart-container, you can now drag from the bottom right corner to see how the layout adapts:

body {
  margin: 1vh;
}

* {
  box-sizing: border-box;
}

h1 {
  margin: 0;
}

.cart-container {
  resize: both;
  overflow: hidden;
  display: flex;
  flex-direction: column;
  gap: 16px;
  height: 98vh;
}

.cart-items-container {
  display: flex;
  flex-direction: column;
  flex-grow: 1;
}

.cart-items {
  padding: 8px;
  overflow: auto;
  background-color: #EEEEEE;
  border: 2px solid orange;
  height: 50px;
  flex-grow: 1;
}

.cart-rest-details {
  display: flex;
  flex-direction: column;
  gap: 4px;
  width: 90%;
  padding: 5%;
  background-color: dodgerblue;
  color: white;
}

The flexbox algorithm prioritizes your max-height as a minimum height and won't shrink below it, so using a low initial height and allowing flex-grow to adjust dynamically should achieve the desired outcome.

Answer 3

Answer №2

To address the issue, you can try inserting min-height: 0; into the styling for .cart-items-container.

Typically, a child element within a flexbox layout won't shrink below its intrinsic content size (min-content) even with flex-shrink applied. By including min-height: 0, this default behavior is overridden, allowing the element to properly resize and display the expected scrollbar.

.cart-container {
  display: flex;
  flex-direction: column;
  gap: 16px;
  width: 100%;
  height: 100vh;
}

.cart-items-container {
  display: flex;
  flex-direction: column;
  /* added */
  min-height: 0;
}

.cart-items {
  padding: 8px;
  max-height: 300px;
  overflow: auto;
  background-color: #EEEEEE;
  border: 2px solid orange
}

.cart-rest-details {
  display: flex;
  flex-direction: column;
  gap: 4px;
  width: 90%;
  padding: 5%;
  background-color: dodgerblue;
  color: white;
}

@media screen and (max-width: 768px) {
  .cart-items-container {
    flex-grow: 1;
  }

  .cart-items {
    flex-grow: 1;
    max-height: none;
  }
}
