CSS Flex

1. 外層屬性

Flex 要加在父層上面，舉例

.container{
  background-color:#004466;
  padding:10px;
  display:flex;
  width: 500px;
}
.item{
  background-color: #00ffa2;
  width: 100px;
  font-size:32px;
  margin:10px;
  text-align:center;
}

<div class="container">
  <div class="item">1</div>
  <div class="item">Lorem ipsum dolor sit amet consectetur adipisicing elit. Facere ipsam accusantium totam maxime dolore est ad doloremque a labore? Aliquid non consequatur nesciunt atque voluptas ea magni natus dolores cum?</div>
  <div class="item">3</div>
  <div class="item">4</div>  
</div>
