覆盖Wordpress默认样式表

标签: css wordpress wordpress-theming

美好的一天。

我正在使用Wordpress主题,我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Appearance> Editor中编辑样式表,我甚至为所有样式添加了!important。但Wordpress会使用默认样式表覆盖我的样式。

现在我读一下有关在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...我不知道在哪里添加我的CSS ...

这是functions.wp-styles.php页面中的代码:我应该在这里定义吗? 非常感谢您的帮助!

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

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)添加到根文件夹中(与functions.php相同的文件夹)。我相信会做到这一点

代码最后一行中引用的10是默认优先级。如果它第一次不起作用,请尝试优先级11

JetPack插件是您的选择吗?它们提供自定义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。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,并随意调用它(BackpressChildTheme,或DavidVanStaden等)。

然后添加样式表(“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,最重要的一行是“Template:”,请确保匹配“父”主题(BackPress)的文件夹名称。

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,将其更改为get_stylesheet_directory_uri。

现在,如果您更新主题,则会保留您在子主题中所做的所有更改。
