Answer 1

您可以使用flexbox尝试以下解决方案：

.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

你可以自己flexbox这样做，你不需要calc来设置位置 - 位置绝对 - 所以这就是我所做的：< / p>

1. 您可以使reg_form_fields_icon_box成为flexbox 垂直且水平对齐。

2. 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;
   }
   

3. 现在定位reg_form_fields_icon 绝对并使用以下内容将其与 bottom 对齐：

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

见下面的演示：

＆＃13;
＆＃13;
.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;
}
