如何在 Mozilla 浏览器的“选择周围箭头”中删除边框和箭头

我在我的 HTML 中使用了 select，它适用于其他浏览器，但我在 Mozilla 浏览器中的 select 内的箭头周围出现了一个带边框的框 有什么办法解决吗？？我不希望它周围只有箭头这样的边界。 这是小提琴的链接https://jsfiddle.net/0zh3fa97/

Answer 1

你可以添加这个： -moz-appearance:none;

select.form-control {
   -moz-appearance:none;
   -webkit-appearance: none;
   appearance:none;
   background-image: url('https://maxcdn.icons8.com/Share/icon/Arrows//expand_arrow1600.png');
   background-repeat: no-repeat;
   background-size:15px;
   background-position: right center;
}


select{
  width:150px;
}

<select class="form-control css-select">
<option data-display="Fright Type">Air Frieght</option>
<option value="1">Road Frieght</option>
<option value="2">Ship Frieght</option>
<option value="3">Rail Frieght</option>
</select>

Answer 2

如果你说的是蓝色边框，你可以试试这个：

.form-control {
    border: 0;
    box-shadow: none !important;
}

Answer 3

在此之前尝试通过此代码删除浏览器外观

.your-class{
   -webkit-appearance: none;
   -moz-appearance:    none;
   appearance:         none;
}
