`Count the number of rows needed to accommodate text line breaks within a div element`

Is there a method to determine the number of lines that text breaks into using the CSS property word-break: break-all? For example, if I have a div like this:

<div>Sample text to check how many lines the text is broken into</div>

And the corresponding CSS is:

div {
  width: 100px;
  word-break: break-all;
}

When viewed in the browser, the text will appear as shown in the image below. How can I calculate the number of lines it has broken into from the original text?

Please provide guidance on achieving this.

Answer №1

If you want to find out how many lines fit in a container based on its line height, you can use the following code:

function calculateLines($container) {
    var lineHeight = parseFloat(window.getComputedStyle($container[0], null).getPropertyValue("line-height"), 10);
    var containerHeight = $container.height();
    var lines = Math.round(containerHeight / lineHeight);
    return lines;
};

//Simply call the function and provide your container class/selector
var totalLines = calculateLines($('.my-container'));

Answer №2

To determine the accurate line height and identify other styles impacting the overall height, one should examine the offsetHeight of the paragraph. Once you obtain the total height, subtract any CSS-related elements and then divide by the line height.

Please note: I am composing this response on my mobile device and have not conducted any testing.

Answer №3

To implement hyphens at the word break, you can utilize the hyphens CSS property.

Code Snippet:

div {
  max-width: 150px;
  hyphens: auto;
  margin:auto;
}

p {
  -webkit-hyphens: auto;
  -moz-hyphens: auto;
  -ms-hyphens: auto;
  hyphens: auto;
}
<div>
  <p>Now in some circumstances, designers may use squares and rectangles to help you visualize what should and could be in a specific location.</p>
</div>

However, this solution may encounter browser support issues.

I came across a useful article discussing the CSS hyphens
