<div style="position: relative; background-color: gray; padding: 1%; width: 100%; height: 60px;">
<div style="background-color: green; width: 50%; height: 100%">
<span style="position: absolute; display: inline-block; text-align: center; width: 100%; vertical-align: middle">
50%
</span>
</div>
</div>

由于您知道外部div的高度为60px,因此您可以设置跨度的行高以匹配它:
<div style="position: relative; background-color: gray; padding: 1%; width: 100%; height: 60px;">
<div style="background-color: green; width: 50%; height: 100%">
<span style="position: absolute; display: inline-block; text-align: center; width: 100%; vertical-align: middle;line-height: 60px;">
50%
</span>
</div>
</div>
