如何在元素中对齐一半的文本？

<style>
    .container {
        display: flex;
        justify-content: center;
        align-items: center;
    }
</style>
<div class="container">
    <span>文本内容</span>
</div>

<style>
    .container {
        position: relative;
    }
    .text {
        position: absolute;
        top: 50%;
        left: 50%;
        transform: translate(-50%, -50%);
    }
</style>
<div class="container">
    <span class="text">文本内容</span>
</div>
