How can we append ellipses (...) to indicate truncation on a multi-line `` element with a fixed width and height?

Ellipsis Handling for Fixed-Width, Multi-Line Text Overflow

In the realm of web development, the need arises to elegantly handle text overflow within a container with specified width and height. How can we append ellipses (...) to indicate truncation on a multi-line

element?

Possible Solution:

jQuery offers a solution with the following markup and CSS:

<code class="html"><div id="fos">
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit...</p>
</div></code>

Copy after login

<code class="css">#fos {
  width: 300px;
  height: 190px;
  overflow: hidden;
}
#fos p {
  padding: 10px;
  margin: 0;
}</code>

Copy after login

The jQuery code repeatedly trims the last word of the text until the desired height is reached:

<code class="javascript">var $p = $('#fos p');
var divh = $('#fos').height();
while ($p.outerHeight() > divh) {
  $p.text(function (index, text) {
    return text.replace(/\W*\s(\S)*$/, '...');
  });
}</code>

Copy after login

Considerations:

This technique ensures a visually correct result, even with JavaScript disabled.
Server-side truncation can improve performance.
This is an incomplete solution and requires further refinement for a practical implementation.
