大概实现效果如图

实现代码

方式1

父元素：line-height 子元素：vertical-align

<!DOCTYPE html>
<html lang="zh-cmn-Hans">
<head>
<meta charset="utf-8" />
<title>垂直居中练习</title>
<meta name="author" content="" />
<style>
    .content{
        width: 600px;
        height: 50px;
        border: 1px solid #000;
        margin: 0 auto;
        font-size: 0;
        line-height: 50px;
        margin-top: 200px;
    }
    .content a{
        display: inline-block;
        width: 25%;
        height: 40px;
        background: cadetblue;
        font-size: 16px;
        text-align: center;
        vertical-align: middle;
        text-decoration: none;
        line-height: 40px;
    }
</style>
</head>
<body>
    <div class="content">
        <a>测试1</a>
        <a>测试2</a>
        <a>测试3</a>
        <a>测试4</a>
    </div>
</body>
</html>

方式2

添加元素调整基准线

<!DOCTYPE html>
<html lang="zh-cmn-Hans">
<head>
<meta charset="utf-8" />
<title>垂直居中练习</title>
<meta name="author" content="" />
<style>
    .content{
        width: 600px;
        height: 50px;
        border: 1px solid #000;
        margin: 0 auto;
        font-size: 0;
        margin-top: 200px;
    }
    .content a{
        display: inline-block;
        width: 25%;
        height: 40px;
        background: cadetblue;
        font-size: 16px;
        text-align: center;
        vertical-align: middle;
        text-decoration: none;
        line-height: 40px;
    }

    .content span{
        display: inline-block;
        height: 50px;
        vertical-align: middle;
    }
</style>
</head>
<body>
    <div class="content">
        <a>测试1</a>
        <a>测试2</a>
        <a>测试3</a>
        <a>测试4</a>
        <span>x</span>
    </div>
</body>
</html>

方式3

伪元素调整基线

<!DOCTYPE html>
<html lang="zh-cmn-Hans">
<head>
<meta charset="utf-8" />
<title>垂直居中练习</title>
<meta name="author" content="" />
<style>
    .content{
        width: 600px;
        height: 50px;
        border: 1px solid #000;
        margin: 0 auto;
        font-size: 0;
        margin-top: 200px;
    }
    .content a{
        display: inline-block;
        width: 25%;
        height: 40px;
        background: cadetblue;
        font-size: 16px;
        text-align: center;
        vertical-align: middle;
        text-decoration: none;
        line-height: 40px;
    }
    .content::after{
        content: 'x';
        display: inline-block;
        height: 50px;
        vertical-align: middle;
    }
</style>
</head>
<body>
    <div class="content">
        <a>测试1</a>
        <a>测试2</a>
        <a>测试3</a>
        <a>测试4</a>
    </div>
</body>
