如何将引导表单控件填充设置为 0 px

Question

我在将 Bootstrap 表单控件填充设置为 0 时遇到问题。我尝试.form-control在样式中添加类，但没有成功。我相信应该可以覆盖样式块中 CSS 类的一些属性。

如何将.form-control填充设置为 0？

<wicket:head xmlns:wicket="http://wicket.apache.org/">
 <styles>
     .form-control {
        padding: 0px;
     }

 </styles>
</wicket:head>

将 0 填充的类“p-0”添加到您想要的 div，

class="other-class p-0"
