Css flex-box - How to align a single item to the bottom while keeping the other items to the top

Question

I've been playing with flex-box for a while but now I'm stuck with an issue. I made a few boxes and in each box there are 3 items inside, an image a paragraph and a button. The image and the paragraph need to stay on top while the buttons need to be aligned on the bottom of their row. Thank you for your time :)

Answer 1

The child is basically a column so you can use flexbox and flex-direction column.

.parent {
  width: 500px;
  display: flex;
  flex-wrap: wrap;
}
.parent .child {
  border: 1px solid black;
  flex: 1 1 32%;
    display: flex;
    flex-direction: column;
    align-items:flex-start;

}

.parent .child input {
  width: 100%;
  margin-top: auto;
  align-self: flex-end; 
}

.parent {
  width: 500px;
  display: flex;
  flex-wrap: wrap;
}
.parent .child {
  border: 1px solid black;
  flex: 1 1 32%;
  display: flex;
  flex-direction: column;
  align-items: flex-start;
}
.parent .child img {} .parent .child input {
  width: 100%;
  margin-top: auto;
  align-self: flex-end;
}

Answer 2

You can do this:

Use position: absolute to fix the button on the bottom and give the same padding-bottom to the main div to adjust your height button needs.

CSS

.parent {
    width: 500px;
    display: flex;
    flex-wrap: wrap;
}
.parent .child {
    border: 1px solid black;
    flex: 1 1 32%;
    position:relative;
    padding-bottom: 20px;
    box-sizing: border-box;
}
.parent .child img {
    max-width: 100%;
}
.parent .child input {
    width: 100%;
    bottom: 0;
    position: absolute;
}
