如上图，怎么改css才能让图片固定在中间，并且可以增加宽度和高度。现在一增加高度或宽度就变形。margin：0 auto；也不好使

.ruleZhezhao{

    height: 100%;

    width: 100%;

    position: fixed;

    background-color:rgba(0, 0, 0, .5);

    z-index: 2;

    top: 0;

    left: 0;

    display: flex;

    flex-direction: column;

    align-items: center;

    justify-content: center;

}

.ruleZhezhaoContent{

}

.ruleZhezhaoimage{

    width: 800rpx;

}

<image class=“ruleZhezhaoimage” src=“https://www.xxxxx/upload/3369f6d59bf2463fa9b4665fcd9b4d64_0429.png” mode="widthFix"></image>
