Determining the height of a div containing text and set width: a step-by-step guide

Check out my code snippet:

<div class="content">
                        <a href="/profile/Nat's Rare &amp; Raw" class="link-name"><strong>Irene Natalia</strong></a>
                        Hooray! we'll proceed with the shipping and inform the tracking # tomorrow :) Thank you, Angel! :)

                        <br>
                        <span class="date">7 days ago</span>
                    </div>

I'm trying to determine the height of this div using javascript. Is there a method for accomplishing this task? The width of this div is fixed at 150px. I am specifically interested in knowing its height in case the content changes. I would prefer using jQuery, but regular Javascript works too.

UPDATE:

An important detail to note here is that this calculation needs to be made before the div is rendered on the webpage. I am working on creating a pinterest-style layout and need to calculate the comment section's height within each item card so that masonry can arrange it properly even before the image loads.

Answer №1

JavaScript:

element.offsetHeight;

This code snippet returns the height of an element.

For more information on offsetHeight visit the Mozilla Developer Network documentation.

jQuery:

$elem.height(); - provides the height of the element excluding padding, border, and margin

$elem.innerHeight(); - gives the height including padding

$elem.outerHeight(true); - includes padding, border, and margin in the height calculation

EDIT:

If you need to determine the height of an element before it is displayed, here is a possible solution:

Append the element with its innerHTML content to the body
Calculate the height using one of the methods mentioned above
Remove the element after obtaining the height, noting that the element will no longer be present

When using jQuery: The height property will provide the height excluding border or padding, innerHeight includes padding but not border, and outerHeight includes both border and padding with an option to include margin as well.

In vanillaJS, like Prasath K mentioned, offsetHeight will give you the height including padding and border.

If an element is not in the DOM, it's challenging to calculate its height. One workaround is to add it somewhere in the DOM, use one of the above methods to calculate its height, and then remove it again.

Answer №7

Another way to ensure the element is not factored into calculations on screen is to apply the CSS property visibility: hidden. Using display: none may not work as expected since the element is often perceived as having zero dimensions in this state.

An alternative approach is to render the element within a div located underneath an obscuring element, with a negative z-index.
