Question

我正在尝试更改默认的Bootstrap表单样式以获得类似于图片显示的表单样式（只是下划线）

但是，我无法删除Bootstrap表单所具有的默认灰色边框。我该如何删除它。（请在此帖附上找到代码）

总结一下，我想保留红色底线并删除我的代码的灰线。

由于

.form-control {
    background-color: transparent !important;
    background-image: none !important;
	border-bottom-color:red !important;
	border-bottom-style:solid !important;
	border-bottom-width:1px !important;
	
    border-radius: 0 !important;
    box-shadow: 0 !important;
    display: block !important;
    font-size: 15px !important;
    height: 45px !important;
    line-height:  1!important;
    padding: 5px 20px 20px 14px;

Answer 1

** 方法-1 ：直接更新引导类**

.form-control
{
  border:none !important
}

Answer 2

设置label，然后设置Border:0px。这就是你所需要的一切。

＆＃13;

Border-bottom-width

＆＃13;

.form-control {
  background-color: transparent !important;
  border: 0px solid !important;
  border-radius: 0 !important;
  background-image: none !important;
  border-bottom-color: red !important;
  border-bottom-style: solid !important;
  border-bottom-width: 1px !important;
  box-shadow: none !important;
  display: block !important;
  font-size: 15px !important;
  height: 45px !important;
  line-height: 1!important;
  padding: 5px 20px 20px 14px;
  width: 100%;
}
