无法在主动链接上覆盖线性梯度

Question

我有一个引导导航，我添加了一个简单的CSS过渡。当用户徘徊在链接上时，它会正确擦拭并将背景颜色更改为蓝色。当用户在链接页面上时， .navactive将添加到<li>类中。这应该使背景颜色实心蓝色，因此用户知道他们在该页面上。线性梯度一直在克服这一点。

有办法

• 覆盖过渡并使其固体
• 禁用链接中与.navactive的链接过渡

谢谢

.nav li {
  /* Old browsers */
  background: linear-gradient(to right, #0943A7 50%, #FFFFFF 50%);
  background-size: 200% 100%;
  background-position: right bottom;
  margin-left: 10px;
  transition: all 1s ease;
}
.nav li:hover{
  background-position: left bottom;
}
.navactive {
  background-color: #0943A7 !important;
  overflow: hidden;
  transform: skewX(-18deg);
  -webkit-transform: skewX(-18deg);
  -ms-transform: skewX(-18deg);
}

html：

<nav class="navbar navbar-expand-lg navbar-light bg-faded">
  <div class="container">
   <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="true" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse show" id="navbarResponsive">
      <ul class="nav justify-content-center mx-md-auto">
        <li class="<?php echo ($page == "home" ? "nav-item navactive" : "nav-item")?>">
          <a class="nav-link" href="index.php">Home</a>
        </li>
        <li class="<?php echo ($page == "page2" ? "nav-item navactive" : "nav-item")?>">
          <a class="nav-link" href="#">Page 2</a>
        </li>
      </ul>
    </div>
  </div>
</nav>

Answer 1

在这里发生了两件事：

• .navactive上的CSS特异性低于.nav li
• background:~~~是background-image的速记，background-image覆盖background-color

将.navactive规则更改为.nav li.navactive应照顾特异性。

将background-image:none;添加到.navactive规则将确保background-color将显示。

.nav li {
  /* Old browsers */
  background: linear-gradient(to right, #0943A7 50%, #FFFFFF 50%);
  background-size: 200% 100%;
  background-position: right bottom;
  margin-left: 10px;
  transition: all 1s ease;
}
.nav li:hover{
  background-position: left bottom;
}
.nav li.navactive {
  background-color: #0943A7 !important;
  background-image:none;
  overflow: hidden;
  transform: skewX(-18deg);
  -webkit-transform: skewX(-18deg);
  -ms-transform: skewX(-18deg);
}

<nav class="navbar navbar-expand-lg navbar-light bg-faded">
  <div class="container">
   <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="true" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse show" id="navbarResponsive">
      <ul class="nav justify-content-center mx-md-auto">
        <li class="nav-item">
          <a class="nav-link" href="index.php">Home</a>
        </li>
        <li class="page2 nav-item navactive" >
          <a class="nav-link" href="#">Page 2</a>
        </li>
      </ul>
    </div>
  </div>
</nav>

在侧节点上，您可能需要使用 font-style:italic而不是skewx。
