jQuery関数はセクションを非表示にしません

Question

空のコンテナを非表示にする関数を使用していますが、1つのセクションでは機能しません。ここ

コードである：

$('.lmla-hidden').each(function() { 
     if ('' === $.trim($(this).text())) { 
     $(this).hide(); 
     } 
    }); 

それが適用されている場所です：

<section class="section-wrapper-projects lmla-hidden"> 

      <h2 class="section-title lmla-hidden"><?php echo CFS()->get('course_details_title_project'); ?></h2> 

      <div class="projects-description lmla-hidden"> 
         <?php echo CFS()->get('design_cycle'); ?> 
        </div> 

      <div class="single-project-wrapper lmla-hidden"> 
         <p class="project-title lmla-hidden"><?php echo CFS()->get('project_title'); ?></p> 

         <div class="project-image lmla-hidden"><img src="<?php echo CFS()->get('project_image'); ?>"></div> 

         <style> .project-link-btn a {color: <?php echo CFS()->get('link_text_colour'); ?>;} </style> 
         <style> .project-link-btn {background: <?php echo CFS()->get('project_link_colour'); ?>;} </style> 

         <div class="project-link-btn lmla-hidden"><?php echo CFS()->get('projects_link'); ?></div> 

        </div> 

     </section> 

パディング底性が依然としてセクションに適用されています。

すべてが機能しているようです。

$('.lmla-hidden').each(function() { 
 
    if (!$.trim($(this).text())) { 
 
    $(this).hide(); 
 
    } 
 
});

.project-link-btn a { 
 
    color: red; 
 
    background: black; 
 
} 
 

 
.project-link-btn { 
 
    background: black; 
 
} 
 

 
.lmla-hidden { 
 
    border: 1px solid black; 
 
    margin: 5px; 
 
    padding: 3px; 
 
}
