  .answerBox>.x-section{display:flex;flex-wrap:wrap;justify-content:space-between}
 
  .answerBox > .x-section>.section{x-width:33%}
  .answerBox > .x-section > hr{width:100%}
 
  .x-ui-field-contain .ui-select{width:auto!important;}
  .x-ui-field-contain >.ui-btn-inline{max-width: 100%!important;}
style>

.answerBox>.x-section 是说在class=answerbox的标签下的哪一行class=x-section标签适用后面的style
如果是.answerBox .x-section 的话，表示class=answerbox的标签下的所哟class=x-section的标签全部继承大括号内的style，也就是说这种样式会影响其他地方的块儿元素的结构的意思否

感谢解答

.answerBox>.x-section只对下面直接子节点有效

.answerBox .x-section则是answerBox 样式容器下的所有包含x-section的节点有效
