Create a textarea and the task is to automatically resize it when we type or paste the content in it. It can be achieved by using JavaScript and jQuery. ,How to create auto-resize textarea using JavaScript/jQuery ?,The ‘input’ event is fired whenever the value of an input or textarea changes. This event can be detected using the addEventListener() method. The callback function of this method is set to the new function created above. This will trigger the textarea to resize whenever any text input is detected, therefore automatically resizing according to the text being typed or pasted.,This will make the textarea’s height equal to the height of the whole text area, effectively resizing the textarea to fit the text.

When the user starts typing, the textarea content is placed to the clone DIV.,Our example code provides a simple way to add the auto-resize feature to textarea element using jQuery.

So, the textarea height will be fit to content and scrollbar not visible to the user.,JavaScript Code: The following code makes the textarea element auto adjustable using jQuery.,HTML Code: Add the textarea element which you want to auto resize.

At first, include the jQuery library.

HTML Code:
Add the textarea element which you want to auto resize.

• When the user starts typing, the textarea content is placed to the clone DIV.
• The height of the clone DIV is applied to texrarea.
• You need to specify the element selector ( #content ) in the textArea variable.

How to Set the Size of the Element

There are two ways of setting the size of the HTML element. You can use HTML or CSS.

In HTML, you can use the cols and rows attributes. Let’s see this solution in use.

Example of setting the textarea size with HTML:

html> html> head> title>Title of the document title> head> body> form action="/form/submit" method="post"> textarea name="textarea" rows="5" cols="40">Write something here textarea> br> input type="submit" name="submitInfo" value="Submit"> form> body> html>

Result

In CSS, you need to use the width and height properties for the element.

Example of setting the textarea size with CSS:

html> html> head> title>Title of the document title> style> textarea < width: 250px; height: 100px; > style> head> body> form action="/form/submit" method="post"> textarea> textarea> br> input type="submit" name="submitInfo" value="Submit"> form> body> html>

How to make a textarea in HTML the same size as its contents?

To make a textarea in HTML the same size as its contents, you can use JavaScript to adjust the height of the textarea dynamically based on its content. Here’s an example of how to do it using jQuery:

html> html> head> title>Resizable Textarea title> script src="https://code.jquery.com/jquery-3.6.0.min.js"> script> style> textarea < min-height: 50px; padding: 10px; font-size: 16px; line-height: 1.5; resize: none; /* disable resizing */ > style> head> body> textarea id="myTextarea"> textarea> script> $(document).ready(function ( ) < $("#myTextarea").on("input", function ( ) < this.style.height = "auto"; this.style.height = this.scrollHeight + 10 + "px"; >); >); script> body> html>

In this example, we first define some CSS styles for the textarea to set its minimum height, padding, font size, line height, and to disable resizing. Then, we use jQuery to attach an event handler to the textarea’s input event. This event fires whenever the textarea’s content changes.

Inside the event handler, we first set the textarea’s height to «auto» to reset it to its default height. Then, we set its height to the scroll height (which includes the content height and any padding or borders) plus an additional 10 pixels of padding. This ensures that the textarea’s height is always large enough to fit its content.

By doing this, the textarea will dynamically adjust its height to match the height of its content as the user types or pastes into it.

How to set a fixed height and width for a textarea element in HTML?

You can set a fixed height and width for a textarea element in HTML by using the rows and cols attributes. The rows attribute sets the number of visible text lines in the textarea, while the cols attribute sets the number of visible characters per line.

To disable the resizing capability of the textarea, you can use the resize property in CSS and set it to none .

Here’s an example of how to set a fixed height and width for a textarea element:

html> html> head> title>Resizable Textarea title> head> body> textarea rows="10" cols="50" style="resize: none;"> textarea> body> html>

In this example, the textarea has a fixed height of 10 rows and a fixed width of 50 characters per row. The resize property is set to none to disable resizing.

Auto Grow a Textarea with Javascript

The key to understanding an auto-growing or self-resizing textarea is to understand the concept of scrollHeight .

Every HTML element has the scrollHeight property that gives the total height of its content. Total height of the content includes the height of the visible content, height of the hidden content (hidden due to the vertical scrollbar) and the top & bottom padding.

So scrollHeight = ENTIRE content & padding

You can get scrollHeight through Javascript :

document.querySelector("#textarea-element").scrollHeight

$("#textarea-element").get(0).scrollHeight

Understanding how Auto-Growing a Textarea Works

In normal cases when content in a textarea overflows, you get to see the scrollbar. Now to make the textarea autogrow, you must hide the scrollbar and adjust the height of the textarea to the height of the contents in it. This adjustment of height should occur whenever the height of the contents change.

scrollHeight of the textarea will give you the height of the entire content of the textarea. With each keydown event (or keyup or input), you must make the height of the element equal to its scrollHeight .

As pointed by a reader, you should use the input event for a smooth behavior.

Demo

Try entering text in the below textarea, and see it auto-grow :

HTML / CSS / Javascript

$("#message-box").on('input', function() < var scroll_height = $("#message-box").get(0).scrollHeight; $("#message-box").css('height', scroll_height + 'px'); >); 

Make sure that you are setting box-sizing: border-box . Otherwise you will see that textarea grows in size with each keydown event. This happens because when you set CSS height to scrollHeight, height = scrollheight + top & bottom padding. Now updating the height will update the scrollHeight as well, and on the next occurance of the event, padding is added again. This almost becomes a loop with padding being added every time. You can find more in this Stack Overflow question.
