主要是设置div的样式为：width:100%;height:100%;display: block;

<style>.layui-tab-item{width:100%;height:480px;}
</style><div class="layui-tab layui-tab-brief" lay-filter="component-tabs-brief"><ul class="layui-tab-title"><li class="layui-this">硫磺固体出入库</li><li  onclick="clickYeti()">硫磺液体出入库</li></ul><div class="layui-tab-content"><div class="layui-tab-item layui-show" style=""><!--  固体硫磺 出入库，曲线图  --><div id="sufulrSolidChart" style="width:100%;height:100%;display: block; " lay-ignore></div></div><div class="layui-tab-item" style=""><!-- 硫磺液体出入库，曲线图  --><div id="liquidSufulrChart" style=" width:100%;height:100%;display: block; " lay-ignore></div></div></div></div>
