Vertical align inline-flex elements - css

Question

I am trying to vertical-align 3 different inline-flex elements in a same div, but the last one doesn't fit as expected.
.container {
height: 100px;
width: 100%;
background-color: blue;
}
.container .left, .container .right {
height: 100%;
width: 30%;
}
.container .middle {
height: 100%;
width: 40%;
}
.container .left, .container .middle {
display: -webkit-inline-flex;
-webkit-justify-content: center;
-webkit-align-items: center;
display: -moz-inline-flex;
-moz-justify-content: center;
-moz-align-items: center;
}
.container .right {
display: -webkit-inline-flex;
-webkit-box-orient: vertical;
-webkit-box-direction: normal;
-webkit-flex-direction: column;
-webkit-box-pack: center;
-webkit-flex-pack: center;
-webkit-justify-content: center;
-webkit-flex-align: center;
-webkit-align-items: center;
display: -moz-inline-flex;
-moz-justify-content: center;
-moz-align-items: center;
-moz-flex-direction: column;
}
.container .right ul {
padding: 0;
margin: 0;
}
<div class="container">
<div class="left">
<span>2014/01/21</span>
</div><div class="middle">
<button>Hello</button>
<button>Bye</button>
</div><div class="right">
<ul>
<li>Chocolate</li>
<li>Caramel</li>
<li>Watermelon</li>
</ul>
</div>
</div>

Answer 1

Just add vertical-align:top to .container .right :
.container .right {
display: -webkit-inline-flex;
-webkit-box-orient: vertical;
-webkit-box-direction: normal;
-webkit-flex-direction: column;
-webkit-box-pack: center;
-webkit-flex-pack: center;
-webkit-justify-content: center;
-webkit-flex-align: center;
-webkit-align-items: center;
vertical-align: top;
}
