CSS中的vertical-align属性

  1,vertical-align属性的作用?

    设置元素垂直对齐的方式;

  2,该属性使用过程的注意点:

    与text-align属性不同,text-align属性是设置给需要对齐元素的父元素的,

    而vertical-align属性是设置给需要对其元素本身的;

  3,该属性的取值有哪些?

    3.1,top (与顶部对齐);

    3.2,bottom (与底部对齐);

    3.3,text-top (与文字顶部对齐);

    3.4,text-bottom (与文字底部对齐);

    3.5,baseline (与基线对齐);

    3.6,middle (与中线对齐)

  4,具体示例:该示例是通过设置图片六种不同的垂直对齐属性来进行对齐的

    

<style>
        div{
            width: 400px;
            margin: 45px auto;
            font-size: 40px;
            line-height: 100px;
        }
        img{
            height: 80px;
        }
        div:nth-child(1){
            background-color: red;

        }
        div:nth-child(1)>img{
            /*默认对齐方式基线对齐*/
            vertical-align: baseline;
        }
        div:nth-child(2){
            background-color: green;
        }
        div:nth-child(2)>img{
            /*顶部对齐*/
            vertical-align: top;
        }
        div:nth-child(3){
            background-color: blue;

        }
        div:nth-child(3)>img{
            /*底部对齐*/
            vertical-align: bottom;
        }
        div:nth-child(4){
            background-color: pink;

        }
        div:nth-child(4)>img{
            /*文字顶部对齐*/
            vertical-align: text-top;
        }
        div:nth-child(5){
            background-color: skyblue;

        }
        div:nth-child(5)>img{
            /*文字底部对齐*/
            vertical-align: text-bottom;
        }
        div:nth-child(6){
            background-color: brown;

        }
        div:nth-child(6)>img{
            /*中线对齐*/
            vertical-align: middle;
        }
    </style>
