CSS achieves the effect of rotating the outermost layer of a multi-layer nested structure while keeping other layers unchanged

<!--Avatar area-->
<div class="headPortrait-panel">
    <!--Loading layer-->
    <div class="load-panel loadWhirl">
        <!--Avatar display layer-->
        <div class="headPortrait-img-panel avatarRotation">
            <img src="../assets/img/login/[email protected]"/>
        </div>
    </div>
</div>
