I am confused as to why a flex div takes up 100% width of its parent element. Take the following snippet:
#wrapper {
  width: 100%;
  height: 100px;
  background: green;
}
#flex {
  color: white;
  display: flex;
  flex-direction: row;
  background: blue;
}<div id="wrapper">
   <div id="flex">
     <div>Item</div>
     <div>Item</div>
     <div>Item</div>
     <div>Item</div>
   </div>
</div>Why is the flex div expanding to 100% width of the parent? Is there a way to make the flex div only as wide as the contents within it?
Any help appreciated, Thanks
