我希望 sometext 刚好在 div 边框上方。

.reg_form_fields_icon_box {
  margin: 0 auto;
  display: flex;
  width: 80px;
  height: 80px;
  border: thin #dee5e7 solid;
}
.reg_form_fields_icon_box .reg_form_fields_icon {
  margin: auto;
}
.reg_form_fields_icon_box .reg_form_fields_icon i {
  font-size: 20px;
}

  vertical-align: bottom;
}

任何帮助都会很棒。

谢谢。

Answer 1

您可以尝试使用 flexbox 的以下解决方案：

.reg_form_fields_icon_box {
  margin: 0 auto;
  width: 80px;
  height: 80px;
  border: thin #dee5e7 solid; 
}
.reg_form_fields_icon_box .reg_form_fields_icon {
  display:flex;
  flex-direction:column;
  width:100%;
  height:100%;
  text-align:center;
  justify-content:space-between;
}
.reg_form_fields_icon_box .reg_form_fields_icon i {
  font-size: 20px;
  top:calc(50% - 20px);
}

<div class="reg_form_fields_icon_box text-center">
  <div class="reg_form_fields_icon">
    <i class="glyphicon glyphicon-font"></i>
    <div class="m-t-md text_name">
      <span>sometext</span>
    </div>
  </div>
</div>

Answer 2

添加以下内容css:

div.reg_form_fields_icon_box {
    position: relative;
}

div.reg_form_fields_icon_box div.reg_form_fields_icon div.text_name{
    position: absolute;
    bottom: 0;
}

Answer 3

你可以flexbox自己做，你不需要calc来设置位置 - position 绝对 - 所以这就是我做过：

您可以将 reg_form_fields_icon_box 设为 flexbox，即垂直和水平对齐。

重置 margin: auto 并将其设置为 100% height 和 width

.reg_form_fields_icon_box .reg_form_fields_icon {
  display: flex;
  align-items: center;
  justify-content: center;
  height: 100%;
  width: 100%;
  position: relative;
  margin: 0;
}

现在定位 reg_form_fields_icon absolutely 并将其对齐到 bottom 使用此：

.reg_form_fields_icon_box .reg_form_fields_icon .text_name {
  position: absolute;
  bottom: 0;
  left: 0;
  right: 0;
}

参见下面的演示：

.reg_form_fields_icon_box {
  margin: 0 auto;
  display: flex;
  width: 80px;
  height: 80px;
  border: thin #dee5e7 solid;
}
.reg_form_fields_icon_box .reg_form_fields_icon {
  margin: auto;
}
.reg_form_fields_icon_box .reg_form_fields_icon i {
  font-size: 20px;
}
.reg_form_fields_icon_box .reg_form_fields_icon .text_name {
  vertical-align: bottom;
}
/*ADDED THESE*/

.reg_form_fields_icon_box .reg_form_fields_icon {
  display: flex;
  align-items: center;
  justify-content: center;
  height: 100%;
  width: 100%;
  position: relative;
  margin: 0;
}
.reg_form_fields_icon_box .reg_form_fields_icon .text_name {
  position: absolute;
  bottom: 0;
  left: 0;
  right: 0;
}
