谢谢你的帮助

一个css文件包含CSS。只是CSS。您不能将html或PHP写入CSS文件。如果要使用PHP生成CSS属性，则必须直接在PHP文件（视图）中使用<style>...</style>标记。例如：

<?php $image = get_field('image_projet'); // fetch the ACF field ?> <html> <head> <title>Page's Title</title> <style> .your-div { background-image: url('<?php echo $image; ?>'); } </style> </head> <body>  <div class="your-div"> Lorem Ipsum. </div> </body> </html>

A css file contains CSS. Just CSS. You can't write html or PHP into a CSS file. If you want to generate a CSS property with PHP, you must use the <style>...</style> tags directly in your PHP file (the view). For instance :
