再会。

我正在使用 Wordpress 主题，并且想添加自己的自定义 CSS。现在我尝试在 header.php 文件中的所有其他 php 样式表调用之后添加我自己的单独样式表。我尝试在外观>编辑器中编辑样式表，我什至在我的所有样式中添加了 !important。但是 Wordpress 不断用默认样式表覆盖我的样式。

现在我在functions.wp-styles.php中阅读了一些关于注册/排队样式表的信息，但是那里的代码对我来说是法语......我不知道在哪里添加我的css......

这是functions.wp-styles.php页面中的代码：我应该在这里定义它吗？对你的帮助表示感谢！

您必须在 functions.php 页面中创建一个函数 - 它位于主题根目录中......

function wpse87681_enqueue_custom_stylesheets() {
    if ( ! is_admin() ) {
        wp_enqueue_style( 'mytheme-custom', get_template_directory_uri() . '/custom.css' );
    }
}
add_action( 'wp_enqueue_scripts', 'wpse87681_enqueue_custom_stylesheets', 10 );

只需将 custom.css（这是您的自定义代码）也添加到根文件夹（与 functions.php 相同的文件夹）。我相信这会成功

代码最后一行引用的 10 是默认优先级。如果第一次不起作用，请尝试将优先级设为 11

JetPack 插件适合您吗？它们提供了自定义 css 模块功能，您可以选择添加到现有 CSS 或替换主题的 CSS。如果你还没有，我建议你先看看这个。

DextrousDave 的反应很好。

但是，我建议您制作一个子主题，而不是将文件添加到主题文件夹中。原因是如果您在进行更改后更新主题，它将清除您的更改。要制作子主题，请在“主题”文件夹中创建一个新文件夹，然后将其命名为您喜欢的任何名称（BackpressChildTheme 或 DavidVanStaden 等）。

然后添加一个样式表（“style.css”），并在顶部包含以下代码：

/*
Theme Name:     Backpress Child Theme, or whatever you want to call it
Theme URI:      http://notreallynecessary.com
Description:    Child theme for the BackPress theme 
Author:         David Van Staden
Author URI:     http://davidvanstaden.com/about/
Template:       BackPress
Version:        0.1.0
*/

请注意，最重要的行是“模板：”，确保与“父”主题（BackPress）的文件夹名称相匹配。

接下来添加一个空白的 php 文件，functions.php，并添加 DextrousDave 建议的函数，除了它说 get_template_directory_uri 的地方，将其更改为 get_stylesheet_directory_uri。

Now, if you update your theme, all your changes that are made in your child theme will be preserved.
