CSS flexbox cannot grow 50%

byMR

August 19, 2022

I have the following structure created by flexbox:

https://jsfiddle.net/zkc03rd1/1/

I am trying to divide:

the top left cell as 50px (top) and 100% bottom
the top right cell as 50% and 50%

but it does not work even if I tried many combination for .flex-item-11, .flex-item-12 and .flex-item-31, .flex-item-32, but not worked. Any idea?

>Solution :

This is my solution! the below class was not setting full height so flex didn’t happen properly!

.flex-container-column {
  flex-direction: column;
  height: 100%;
}

.flex-container-row, .flex-container-column {
  display: flex;
  flex-wrap: nowrap;  
  padding: 0;
  margin: 0;
  list-style: none;
}

.flex-container-row *, .flex-container-column * {  
  border: 1px solid tomato;
  text-align: left;
}

.flex-container-row {
  flex-direction: row;
}

.flex-container-column {
  flex-direction: column;
  height: 100%;
}

.flex-item-1 {
  flex: 4 1 100%;
}

.flex-item-11 {
  flex: 0 0 50px;
}

.flex-item-12 {
  flex: 1 0 100%;
}

.flex-item-2 {
  flex: 2 1 50%;
}

.flex-item-3 {
  flex: 1 0 300px;
}

.flex-item-31 {
  flex: 1 1 100%;
}

.flex-item-32 { 
  flex: 1 1 100%;
}
