Question

我尝试使用推荐的引导程序4导航栏样式之一。我将代码粘贴到项目中，并且一切正常。唯一的问题是我已将背景颜色从深色更改为白色。由于导航栏中的文字不可见。我尝试了许多方法来将文本颜色更改为黑色，以便可以看到文本，但是它不起作用，而且我不知道如何将文本颜色从白色更改为黑色。

我尝试在无法正常运行的导航栏类中添加text-black类。

感谢您的帮助。

只需在#navigation *中添加一些CSS，然后使用color设置颜色即可。

#navigation * {
  color: red;
}

  <nav class="navbar navbar-expand-lg navbar-dark bg-white static-top text-black">
    <div class="container">
      <a class="navbar-brand" href="#">
        <img src="images/logo_5_150x60.png" alt="">
      </a>
      <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
                <span class="navbar-toggler-icon"></span>
            </button>
      <div class="collapse navbar-collapse" id="navbarResponsive">
        <ul class="navbar-nav ml-auto">
          <li class="nav-item active">
            <a class="nav-link" href="#">Home
                            <span class="sr-only">(current)</span>
                        </a>

navbar-dark元素上的<nav>类是一种设置文本颜色的类。使用浅背景色时，将navbar-dark更改为navbar-light。

<section id="navigation">
    <nav class="navbar navbar-expand-lg navbar-light bg-white static-top text-black">
        <div class="container">
            <a class="navbar-brand" href="#">
                <img src="images/logo_5_150x60.png" alt="">
            </a>
            <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
                <span class="navbar-toggler-icon"></span>
            </button>
            <div class="collapse navbar-collapse" id="navbarResponsive">
                <ul class="navbar-nav ml-auto">
                    <li class="nav-item active">
                        <a class="nav-link" href="#">Home
