Responsive Squares Divs

I want to have a column with 4 divs with a background-image and fit the 100% of the parent width and give the same to the height to make a square. This is what i have without %: M

Solution 1:

You may use a pseudo element:

.slot {
  box-shadow:inset 005px#C9A170;
  background:#EBE6C9;
  border:solid #78624A;
  overflow:hidden;
  padding:5px;
  margin:1em;
  }
.slot:before {
  content:'';
  float:left;
  padding:50%0;
  }
body {
  margin:0;
  }

<divclass="col-sm-3 slots"style="background-color: red;"><divclass="slot"> anything here</div><divclass="slot"> can grow taller than the initial square shape</div><divclass="slot"></div><divclass="slot"></div></div>

Solution 2:

I don't understand what you're trying to accomplish... if you want those boxes to dynamically change size according to their parent div you need javascript for that, can't do with CSS.

Solution 3:

You can use a vertical padding with a percentage for this:

.slots {
    width: 150px;
}
.slot {
    width: 100%;
    padding-bottom: 100%;
}
