Bootstrap儿童元素高度100％

Question

我想要一个带有2个元素的按钮来滑动背景。

但是我希望这两个元素都能垂直居中，即使其他元素较大时也能获得100％的高度。

下面是HTML

<button class="btn-cstm-slide"> 
    <div class="btn-cstm-slide-logo"><span>Test Test 14343</span></div> 
    <div class="btn-cstm-slide-text"> 
     <span>Just a Testtest</span> 
     <br/> 
     <span>Let's see</span> 
    </div> 
</button> 

而且这里的CSS

.btn-cstm-slide { 
    height: 100%; 
    padding: 0px; 
    display: flex; 
    position: relative; 
    text-decoration: none; 
    overflow: hidden; 
    background: #333C42; 

    border: none; 
    box-shadow: 0px 1px 1px rgba(0,0,0,.1); 
} 
.btn-cstm-slide-logo { 
    height:100%; 

    min-height:100%; 
    margin: 0; 
    padding: 10px; 
    position: relative; 
    text-decoration: none; 
    background: #474f54; 
    color: #fff; 
} 
.btn-cstm-slide-text { 
    padding: 10px; 
    position: relative; 
    text-decoration: none; 
    background: #333C42; 
    color: #fff; 
    -webkit-transition: all 0.5s ease; 
    -moz-transition: all 0.5s ease; 
    -o-transition: all 0.5s ease; 
    transition: all 0.5s ease; 
} 

.btn-cstm-slide-text * { 
    position:relative; 
} 

.btn-cstm-slide-text:before { 
    content: ""; 
    position: absolute; 
    height: 100%; 
    width: 0; 
    bottom: 0; 
    left:0; 
    background-color: #474f54; 
    -webkit-transition: all 0.4s ease-in-out 0s; 
    transition: all 0.4s ease-in-out 0s; 
} 
.btn-cstm-slide-text:hover:before { 
    width: 100%; 
}
