The requirement is to set equal height and equal width of column. I have used css property display table-cell for this and its works fine in terms of equal height but not well with when it comes to equal width. I know technically it is working fine but I want to make it equal width. So whether there is four column or one column in a one table it should come with one width.
I have also looked for flex but its support is not there in IE9 and has some compatibility issue with mobile browser. I have think and tried it many ways but did not got the solution. Here is fiddle if you want to try your hand on it.
HTML
.table {
  display: table;
  width: 100%;
  height: 100%
}
.cell {
  display: table-cell;
  padding: 0 10px;
  width: 23.8%;
  height: 100%
}
.white-box {
  border: solid 1px #ccc;
  background: #eee;
  height: 100%
}<div class="table">
  <div class="cell">
