直接复制运行，简单易懂。

<style>
    .content {
        display: flex;
        flex-direction: column;
        align-items: center;
        justify-content: center;
        zoom: 0.5;
    }

    .logo {
        height: 200rpx;
        width: 200rpx;
        margin-top: 200rpx;
        margin-left: auto;
        margin-right: auto;
        margin-bottom: 50rpx;
    }
</style>

ps：如果父级元素有用到缩放 /zoom对应的缩放比就行
