html - Alignment of content vertically in adjacent flexbox containers

Question

I have multiple items say cards. These cards need to stack horizontally and height needs to be the same. This is happening for me.

Each card has an image, text and a button. Image and text for each card should take what ever is the max height in any card, so that these align properly. This is not happening for me.

If the image and text align properly then the button will always be aligned in each card at the bottom.

I have been following this tutorial but I have multiple cards, putting three here only. Also the third card image height is being set via CSS.

.partner-cards * {
  box-sizing: border-box;
}

.partner-cards {
  display: flex;
  flex-wrap: wrap;
}

.partner-card {
  display: flex;
  flex: 1 0 20%;
  border-radius: 0;
  text-align: center;
  border: 3px solid blue;
  padding: 5px;/*3rem;*/
  margin-bottom: 3rem;
  max-width: 20%;
  margin: 5px;
}

.partner-card-content {
  display: flex;
  flex-direction: column;
}
/*
.card-content .image-container img {
  
  margin: 0;
  padding: 0;
}
*/
.partner-card-content .partner-image-container {
  border: 1px solid green;
  padding: 0;
  margin: 0;
  min-height: 11rem;
                display: flex;
                vertical-align: middle;
                align-items: center;
                justify-content: center;
                max-width: 100%;
}

.partner-card-content p /*, .card-content .image-container*/
{
  flex: 1 0 auto;
  border: 1px solid red;
}

.partner-card-content img.third-image {
  height: 5.5rem !important;
}
/*
p {
  font-size: 16px;
line-height: 26px;
font-family: Averta-Regular,Arial,Helvetica,sans-serif;
margin-bottom: 2.5rem;
margin-top: 0;
}*/

Answer 1

TL;DR

Alignment of flexbox items in adjacent flexboxes is not possible in CSS. You really need sub-grids to solve this problem with dynamic sizes of the sections in your card.

Flexbox Scenario

Anyway given that you have a min-height for the partner-image-container, so I guess you can have either a min-height set for the a or an ellipsis to keep it to a single line. See below solution that adds an ellipsis:

.partner-cards * {
  box-sizing: border-box;
}

.partner-cards {
  display: flex;
  flex-wrap: wrap;
}

.partner-card {
  display: flex;
  flex: 1 0 20%;
  border-radius: 0;
  text-align: center;
  border: 3px solid blue;
  padding: 5px;/*3rem;*/
  margin-bottom: 3rem;
  max-width: 20%;
  margin: 5px;
}

.partner-card-content {
  display: flex;
  flex-direction: column;
  min-width: 0; /* ADDED */
}


/*
.card-content .image-container img {
  
  margin: 0;
  padding: 0;
}
*/

.partner-card-content .partner-image-container {
  border: 1px solid green;
  padding: 0;
  margin: 0;
  min-height: 11rem;
  display: flex;
  vertical-align: middle;
  align-items: center;
  justify-content: center;
  max-width: 100%;
}

.partner-card-content p/*, .card-content .image-container*/ {
  flex: 1 0 auto;
  border: 1px solid red;
}

.partner-card-content img.third-image {
  height: 5.5rem !important;
}


/*
p {
  font-size: 16px;
line-height: 26px;
font-family: Averta-Regular,Arial,Helvetica,sans-serif;
margin-bottom: 2.5rem;
margin-top: 0;
}*/

.primary-button { /* ADDED */
  text-overflow: ellipsis;
  overflow: hidden;
  white-space: nowrap;
}
