What methods can be used to conceal a div when the content is not being shown?

I'm a beginner in HTML and CSS and I have a page with the following code:
Content displayed :

<div id="row-3" ><!-- Row 3 starts here -->

   <div class="groupz_column1" style="margin-right:0px;"><a href="http://www.xyz.in/ads/test.jpg" title=""><h2>null</h2><img align="left" width="100px" height="70px" src="http://www.xyz.in/ads/test.jpg?id=225"><p>Sign off for limited time offer<p></a></div>
   <div class="groupz_column1" style="margin-right:0px;"><a href="http://www.xyz.in/ads/test.jpg" title=""><h2>Test</h2><img align="left" width="100px" height="70px" src="http://www.xyz.in/ads/test.jpg?id=194"><p>A wonderful opportunity <p></a></div>
   <div class="groupz_column1" ></div>
   <div class="groupz_column1" ></div>
   <div class="clear clearfix"></div>
</div>

The above code displays two contents.
Without content displayed:

<div id="row-3" ><!-- Row 3 starts here -->
   <div class="groupz_column1" ></div>
   <div class="groupz_column1" ></div>
   <div class="groupz_column1" ></div>
   <div class="groupz_column1" ></div>
   <div class="clear clearfix"></div>
</div>

My issue is that I want to hide <div id="row-3"> if no content is present. I do not want to display it when there is no content. How can I achieve this?

EDIT I tried the following, but it's still not working

   <div id="row-3" style="div:empty { display: none }">
javascriptjqueryhtmlcss

Answer №1

insert this javascript code

$(document).ready(function () {
   var hideRow = true;
   $("#row-3 div").each(function () {
      if ($(this).html() != '') {
          hideRow = false;
      }
   });

   if (hideRow) {
      $("#row-3").hide();
   }
});

Answer №2

Give this a shot:

$('div[id^=row-]').each(function () {
    var hasContent = false;
    $(this).find('div').each(function () {
        if (this.innerHTML !== '') {
            hasContent = true;
        }
    });
    if (!hasContent) {
        this.style.display = 'none';
    }
});

Answer №3

apply css styling: 

 #row-3{
        visibility: hidden;
    }

Answer №4

To ensure that the content length is greater than zero before displaying it, you can use the following code snippet:

 var checkLength = $("#new_row .group_column").html().trim().length;

if (checkLength == 0) {
    // $("#new_row").remove(); // this will remove the element
    $("#new_row").hide(); // this will hide the element
}

Answer №5

To address the comment, include white-space: nowrap; in your CSS for the groupz_column1 class....this will eliminate any unwanted white space within empty div elements.
