JavaScript has the ability to manipulate the width of an element by using methods to both retrieve

I have a unique situation where I need to dynamically adjust the width of a ul list element based on the text content inside it. Specifically, I want the width of the ul list to be equal to the width of the first list item, which can change frequently. My goal is to retrieve the width of the first list item (#item1) and then apply that same width to the entire ul list (#myList). Despite my efforts with the following code snippet, I have not been successful:

<script type="text/javascript">
  var width = document.getElementById('item1').offsetWidth;
  document.getElementById('myList').style.width = width;
</script>

Here is the HTML structure:

<ul id="myList">
  <li id="item1">text1</li>
  <li>text2</li>
  <li>text3</li>
</ul>

If anyone has any suggestions or solutions that do not involve using jQuery, but rather pure JavaScript, I would greatly appreciate it!

Thank you in advance!

Here's a useful tip: When working with HTML elements, remember to specify the ul element as #ul and the list element as #list in your code.

 var liWidth=document.querySelector('#list').clientWidth;

 // Ensure the width of ul matches
 document.querySelector('#ul').style.width=liWidth+'px';

By following these steps, you can ensure that everything runs smoothly. Just remember to create the necessary elements before executing any JavaScript code to avoid encountering errors related to missing style properties.
