我建议您
header.php 很简单，把你所有的逻辑都放进去
functions.php同时使用wp_enqueue_style 排队stylesheets 和wp_enqueue_script 排队JavaScript. 这样，您就不会破坏与其他插件的兼容性，并确保最佳实践。
参见关于使用的技术辩论WordPress Coding Standards: How to add crossorigin and integrity to wp_register_style? (Font Awesome 5) 和functions.php not adding css to website?
您需要使用after_setup_theme 和wp_enqueue_scripts 挂钩。这些示例是使用Bootstrap 4制作的
示例标题。php
