圖片大於div時的居中顯示

當圖片大於div時,想要圖片居中顯示,若是圖片等比例縮小可能會致使圖片不能填充整個div,若是直接將圖片不設置寬高,將其外層div設置overflow:hidden;這時即便外層div設置了水平垂直居中,圖片也不是居中的效果:javascript

解決方法:css

1-       把圖片設置爲背景圖片java

<div class="face-img-contain" id="face-img-back">
 </div>

 

.face-img-contain{
    width: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;
}

 

如果後臺返回的地址,別忘了拼接方法正確
$("#face-img-back").css("background-image","url("+faceImg+")");

 

2-       給圖片設置相對div的100%的寬高,再設置object-fit:cover;flex

 

<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{
    width: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{
    width:100%;
    height:100%;
    object-fit: cover;
}
