表格和表格单元格不起作用。我把桌子的高度100％和桌子自动。然后我尝试将table-cell设置在vertical-align中间，宽度为100％，但不起作用。我的代码出了什么问题？

*Table and Tablecell rules: if you want to use table and tablecell for making content to center which is up or down/ left or right firstly you need to make 100% height for all div if the table and tablecell are child div then only tablecell need to height auto.
-->
答案 0 :(得分：1)
.welcome-slider-area div {
height: 100%;
}
这使div中的所有.welcome-slider-area成为.slide-item-tablecell，尝试将高度设置为<div class="container" style="height: 100px;">
<!-- content -->
</div>
div的子项。
