div中的文字底部对齐:
<div style="width:100px;height:180px; position:relative;" > <span style=" position: absolute;top: 100%;transform: translateY(-100%);">底部居中</span> </div>
div中的文字居中对齐:
<div style="width:100px;height:180px; position:relative;" > <span style=" position: absolute;top: 50%;transform: translateY(-50%);">底部居中</span> </div>
宽度自动计算:
:root{ --slide-font-div-margin-left: calc(100% - 100px) ; } .slide-font-div{ width:var(--slide-font-div-margin-left); }
