html - Bootstrap 渐变背景无法正确呈现

Question

我的导航栏中有汉堡包图标的背景渐变。 正如您在代码片段结果中看到的那样，它的左右两侧有一些奇怪的“边框”。

如何让这些边框消失？

.btn-primary {
  border-color: transparent !important;
  background-color: transparent !important;
  display: inline-block;
  height: 40px;
  background: #0080eb;
  background: linear-gradient(90deg,#0080eb 0,#00d3eb 100%);
  color: #fff;
  font-size: 13px !important;
  font-weight: 700;
  border-radius: 20px !important;
  padding: 0 9px !important;
  line-height: 40px;
  box-shadow: 0 10px 13px -10px rgba(0,128,235,.75);
}
.bg-primary.container {
  background-color:transparent !important;
}

    <nav class="navbar navbar-expand-md navbar-light bg-primary container">

      <button class="navbar-toggler btn-primary" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
      </button>

      <!-- The WordPress Menu goes here -->
      <div id="navbarNavDropdown" class="collapse navbar-collapse">
      <ul id="main-menu" class="navbar-nav ml-auto">

这是 border 问题，添加 border: 0 !important 就可以了，检查下面:-

.btn-primary {
  border-color: transparent !important;
  background-color: transparent !important;
  display: inline-block;
  width: 40px;
  height: 40px;
  background: #0080eb;
  background: linear-gradient(90deg,#0080eb 0,#00d3eb 100%);
  color: #fff;
  font-size: 13px !important;
  font-weight: 700;
  border-radius: 20px !important;
  padding: 0 9px !important;
  line-height: 40px;
  box-shadow: 0 10px 13px -10px rgba(0,128,235,.75);
  border: 0 !important;
}
.bg-primary.container {
  background-color:transparent !important;
}
