css - 覆盖 Wordpress 默认样式表

Question

美好的一天。

我使用的是 Wordpress 主题，我想添加自己的自定义 CSS。现在我已经尝试在 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 Appearance>Editor 中编辑样式表，我什至添加了 !important 到我的所有样式中。但是 Wordpress 一直用默认样式表覆盖我的样式。

现在我读了一些关于在 functions.wp-styles.php 中注册/排队样式表的内容，但是那里的代码对我来说是法语的...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？ 非常感谢您的帮助!

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)中。我相信这会成功

代码最后一行引用的 10 是默认优先级。如果第一次不行，尝试将优先级设置为 11
