Changing the text color on a nav bar using Materialize CSS (rails)

htmlcssmaterialize

提问by torie

I want to create a navbar with a white background and black text, but have been unable to get the text in the links within the navbar to be anything but white.

我想创建一个带有白色背景和黑色文本的导航栏,但一直无法将导航栏中链接中的文本变为白色。

Things I've tried:
- adding the class "black-text" to the li tags, to the ul tag, to the surrounding div and nav tags
- defining a class in my application.scss file for each li tag.
- adding li, nav, a { color: black; } to my application.scss file

我尝试过的事情:
- 将类“black-text”添加到 li 标签、ul 标签、周围的 div 和 nav 标签
- 在我的 application.scss 文件中为每个 li 标签定义一个类。
- 添加 li, nav, a { color: black; 到我的 application.scss 文件

Here is the html for the navbar:

这是导航栏的 html:

  <header class="nav">
    <nav>
      <div class="nav-wrapper white">
        <a href="/" class="brand-logo black-text">GlobalPursuit</a>
        <ul id="nav-mobile" class="right hide-on-med-and-down">
          <li><%= link_to "Pursuits", pursuits_path %></li>
          <li><%= join_dashboard_path %></li>
          <li><%= login_logout_path %></li>
          <li><%= trips_cart_display %></li>
        </ul>
      </div>
    </nav>
  </header>

Try this with rails, I worked for me, So if you modify the style. see in full page.

用 rails 试试这个,我为我工作,所以如果你修改样式。见整页。

nav ul li a{

As adding a style change to the html will work I would recommend staying within the materializecss framework that you have chosen.

由于向 html 添加样式更改会起作用,我建议您保留在您选择的 materializecss 框架内。

<div class="nav-wrapper"></div>

The default to this nav bar background color is pink, but just add one of the built in colors/shades and you will get very cool effects.

此导航栏背景颜色的默认值是粉红色,但只需添加一种内置颜色/阴影,您将获得非常酷的效果。

<div class="nav-wrapper blue lighten-1></div>

Now my nav bar has a light blue background color. Same applies to the text.

现在我的导航栏有一个浅蓝色的背景色。同样适用于文本。

<div class="card-panel">
      <span class="blue-text text-darken-2">This is a card panel with dark blue text</span>
</div>

This will produce a card panel with blue text. Hope this helps.

这将产生一个带有蓝色文本的卡片面板。希望这可以帮助。

Try this on the brand to have a black text:

在品牌上试试这个有黑色文字:

<a href="#" class="brand-logo black-text">Logo</a>

Looks like the materialize library defines the color as white at the nav ul alevel:

看起来物化库在nav ul a级别将颜色定义为白色:

nav ul a {
    -webkit-transition: background-color .3s;
    transition: background-color .3s;
    font-size: 1rem;
    color: #fff;
    display: block;
    padding: 0 15px;
    cursor: pointer;
}

To overwrite this you would have to add the materialize text-color class to the actual <a>tag in the nav <ul>:

要覆盖它,您必须将 materialize text-color 类<a>添加到 nav 中的实际标签<ul>

<nav>
    <div class="nav-wrapper white">
      <a href="#!" class="brand-logo">Logo</a>
      <a href="#" data-target="mobile-demo" class="sidenav-trigger"><i class="material-icons">menu</i></a>
      <ul class="right hide-on-med-and-down">
        <li><a class="black-text" href="sass.html">Sass</a></li>
        <li><a class="black-text" href="badges.html">Components</a></li>
        <li><a class="black-text" href="collapsible.html">Javascript</a></li>
        <li><a class="black-text" href="mobile.html">Mobile</a></li>
      </ul>
    </div>
  </nav>
