Answer 1

垂直居中有各种技术，但在处理绝对定位时，最好使用

top:50%; left: 50%; transform:translate(-50%,-50%);

* {
    margin: 0;
}

html, body {
    height: 100%;
}

.landing-bg{    
    height: 100%;
    position: relative;
    background: #ccc;
}
.watch-trailer-btn{
    position: absolute; 
    width: 180px;
    height: 20px;
    color: #fff;
    top:50%;
    left: 50%;
    transform:translate(-50%,-50%);
    font-size: 16px;
    font-weight: 600;
    text-decoration: none;
    text-align: center;
    text-transform: uppercase;
    padding: 20px 0;
    border-radius: 8px;
    background: #f1d948;    
}

<div class="landing-bg">

    <a class="watch-trailer-btn" href="#"><span>Watch Trailer</span></a>

</div>

你可以这样做：

    width: 100%;
    height: 1350px;
    display: block;
    position: relative;
}
.watch-trailer-btn{
    position: relative; /*Change to relative*/
    display: block;
    width: 180px;
    height: 20px;
    color: #fff;
    margin: 0 auto;
    /*left: 0;*/
    /*right: 0;*/
    top: 490px;
    font-size: 16px;
    font-weight: 600;
    text-decoration: none;
    text-align: center;
    text-transform: uppercase;
    padding: 20px 0;
    border-radius: 8px;
    background: #f1d948;    
}

这是HTML：

<div class="modal-box visible form-modal">
    <!-- MODAL 01 -->
    <div class="inner-container">
        <div class="text-container">
            <h2>Vivez Lorem</h2>
            <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. .....</p>
        </div>

</div>

这是CSS：

.modal-box .inner-container {
   position: relative;
   width: 465px; 
   /*width: better put in percentage; */
   left: 9px;
   background-color: #FFF;
   display: block;
   margin-left: auto;
   margin-right: auto;
   margin-top: 10%;
   margin-bottom: 10%;}

这是工作example。
