  • 图片大于div时的居中显示

    当图片大于div时,想要图片居中显示,如果图片等比例缩小可能会导致图片不能填充整个div,如果直接将图片不设置宽高,将其外层div设置overflow:hidden;这时即使外层div设置了水平垂直居中,图片也不是居中的效果:

    解决方法:

    1-       把图片设置为背景图片

    <div class="face-img-contain" id="face-img-back">
     </div>
    
    .face-img-contain{
        348px;
        height:436px;
        margin:0 auto;
        margin-top: 14px;
        position: relative;
        background-image: url(../images/face-img/test-22.png); 
        background-repeat: no-repeat;
        background-position: center;
        background-size: cover;
        display: flex;
        justify-content: center;
        align-items: center;
        border: 1px solid gainsboro;
    }
    
    若是后台返回的地址,别忘了拼接方法正确
    $("#face-img-back").css("background-image","url("+faceImg+")");
    

    2-       给图片设置相对div的100%的宽高,再设置object-fit:cover;

    <div class="face-img-contain-new-new">
        <img src="../images/face-img/test-22.png" alt="" class="face-img-defined1" id="face-img-photo">
    </div>
    
    .face-img-contain-new-new{
        348px;
        height:436px;
        margin:0 auto;
        margin-top: 14px;
        position: relative;
        display: flex;
        justify-content: center;
        align-items: center;
        overflow: hidden;
        border: 1px solid gainsboro;
    }
    .face-img-defined1{
        100%;
        height:100%;
        object-fit: cover;
    }
