Use flex-basis Property to Set the Initial Size of an Item

HTML-CSS
1

Tell us what’s happening: can’t we just use height and width property to set the initial size of the item?

Your code so far


<style>
  #box-container {
    display: flex;
    height: 500px;
    
  }
  
  #box-1 {
    background-color: dodgerblue;
    height: 200px;
   FLEX-BASIS: 10em;
  }
  
  #box-2 {
    background-color: orangered;
    height: 200px;
    flex-basis: 20em;
  }
</style>
  
<div id="box-container">
  <div id="box-1"></div>
  <div id="box-2"></div>
</div>

Good question. The main difference is that flex-basis will work on width or height depending if your flex-direction is row or column respectively, while width and height works only on their respective axis.
