Question

如何为 :after 选择器中的背景图像创建自定义字段？问题是我必须改变它

    <span class="project-title"><?php echo $project_title2;?></span>
    <p><?php echo $project_text2;?></p>
</div>


  div#pr0.project-slide:after{
    background-image: url(http://localhost/ruby/wp-content/uploads/2017/05/720_500_specialnij.png);
  }

Answer 1

试试这个。

<div id="pr1" class="project-slide>
    <span class="project-title"><?php echo $project_title2;?></span>
    <p><?php echo $project_text2;?></p>
</div>




div#pr1.project-slide:after{    
    content:url(http://localhost/ruby/wp-content/uploads/2017/05/720_500_specialnij.png);
  }
