Question

我将包含完整的代码，因为我不确定问题出在哪里，但是我要定位的元素是<h1>PC Lee</h1>，因此我试图将字体颜色更改为白色，但是不起作用：

{% extends 'core/base.html' %}
{% load static %}

{% block head %}
<link rel="stylesheet" type="text/css" href="{% static 'core/style/index2.css' %}" />

<!--links specific to style sheet 2 -->
<link href="https://fonts.googleapis.com/css?family=Open+Sans+Condensed:300" rel="stylesheet">{% endblock %}

{% block body %}


    <div id="jumbotron">

        <ul>
            <li class="align_left"><a href="#">PCLee</a></li>
            <li class="align_right"><a href="#">Repairs/Upgrades</a></li>
            <li class="align_right"><a href="#">Networking</a></li>
            <li class="align_right"><a href="#">Remote Backups</a></li>
            <li class="align_right"><a href="#">Data Recovery</a></li>

        </ul>

    <div id="h1_div"><h1>PC Lee</h1>
            <img id="image" src="{% static "core/images/logo.png" %}" alt="My image" height="400" width="200"/>
    </div>

    </div>
<h1>dafs</h1>

    <div id="grid">
        <div id="content">
            <h1>About Us</h1>

            <form role="form" action="" method="post">

    </div>

和CSS：

h1{
    font-family: 'Open Sans Condensed', sans-serif;
    color: white !important;
    font-size: 1em;
}

这些css语句都没有影响h1元素，但是css文件已正确链接，因为所有其他css语句都在工作。感谢您的帮助

Answer 1

您尝试过

.example {
  width: 100px;
  height: 100px;
  
  background-color: black;
  background-size: cover;
}

Answer 2

确保已加载CSS文件。如果已加载，则可以被下面的CSS文件覆盖。将自定义CSS文件保留在您引用的CSS文件之下。

Answer 3

自定义后，您可能会加载一个CSS文件，从而覆盖所需的属性。

CSS选择器未选择h1元素
