在中心对齐锚标记内的内容

Question

我需要帮助让锚内的内容垂直对齐。我在锚标签中使用字体真棒图标和文本。我希望图标和文本在中心垂直和水平对齐。我能够进行水平对齐，但无法进行垂直对齐。不知道我错过了什么

.my-tile {
    height: 90px;
    margin-left: 0.5%;
    margin-right: 0.5%;
    float: left;
    font-family: 'Segoe UI', Tahoma, Geneva, Verdana, sans-serif;
    font-size: 14px;
    /*display: table;*/
    border-radius: 3px;
    -moz-border-radius: 3px;
    -webkit-border-radius: 3px;    
    position: relative;    
    align-items: center;
    background: linear-gradient(#af4b17, #e57234); /* Standard syntax */
    background: -moz-linear-gradient(#af4b17, #e57234 35%, #e57234);
    background: -webkit-gradient(linear,left top,left bottom,color-stop(0, #af4b17),color-stop(.35, #e57234),color-stop(1, #e57234));
    border: 1px solid #af4b17;
    text-align: center;
    justify-content: center;
    vertical-align:middle;
}

    .my-tile > a {
        display: flex;
        align-items: center;

        position: relative;           
        vertical-align:middle;        
    }

        .my-tile > a .link-icon {

            font-size: 30px !important;

Answer 1

对齐内部所有内容的最佳方法<a></a>是使用FLEX

a {
    display: flex;
    align-items: center;
    justify-content: center;

    /** Use this rule if the tag has a parent with specific height */ 
    height: 100%; 
}
