Automatically adjusting the height of a textarea to its content text

Semantically imothis solution is better than the accepted solution because it still uses input fields for user input but it does introduce a little bit of jQuery.

Soundcloud does something similar to this for their tagging. If you set the span to display: inline-block, automatic horizontal and vertical resizing works very well:. Attach a :focus css class to your text box with a larger width. Then your box will be larger when focused.

That's not exactly what you're asking for, but similar.

Check out this question for some ideas. From: Is there a jQuery autogrow plugin for text fields? EDIT: Another solution is to havethe user type what he wants and on blur focus outgrab the string in the same font size place it in a div - count the div's width - and then with a nice animate with a cool easing effect update the input fields width.

The only drawback is that the input field will remain "small" while the user types. Or you can add a timeout : you can check such a kind of solution on the fiddle above too! I know this is a seriously old post - but my answer might be useful to others anyway, so here goes. I found that if my CSS style definition for the contenteditable div has a min-height of instead of a height ofthen the div scales automatically. If you are just interested in growing, you can update the width to scrollWidthwhenever the content of the input element changes.

Which approach you use, of course, depends on what your end goal is. If you want to submit the results with a form then using native form elements means you don't have to use scripting to submit. Also, if scripting is turned off then the fallback still works without the fancy grow-shrink effects.

If you want to get the plain text out of a contenteditable element you can always also use scripting like node. Here's a method that worked for me.In this tutorial, you will learn full details about Excel AutoFit and the most efficient ways to use it in your worksheets. Microsoft Excel provides a handful of different ways to change column width and adjust row height. The easiest way to resize cells is to have Excel automatically determine how much to widen or narrow the column and to expand or collapse the row to match the data size.

This feature is known as Excel AutoFit and further on in this tutorial you will learn 3 different ways to use it. Excel's AutoFit feature is designed to automatically resize cells in a worksheet to accommodate different sized data without having to manually change the column width and row height.

AutoFit Row Height - adjusts the column width to match the largest value in the row. This option expands the row vertically to hold multi-line or extra-tall text. Unlike column width, Microsoft Excel changes the row height automatically based on the height of the text you type in a cell, therefore you won't really need to auto fit rows as often as columns.

However, when exporting or copying data from another source, row heights may not auto adjust, and in these situations the AutoFit Row Height opting comes in helpful.

When resizing cells in Excel, either automatically or manually, please bear in mind the following limits to how big columns and rows can be made. Columns can have a maximum width ofwhich is the maximum number of characters in the standard font size that a column can hold.

Using a bigger font size or applying additional font characteristics such as italics or bold may significantly reduce the maximum column width. The default size of columns in Excel is 8. What I particularly like about Excel is that it provides more than one way to do most things. Depending on your preferred work style, you can auto fit columns and rows by using the mouse, ribbon or keyboard. Those of you who prefer working with the keyboard most of the time, may like the following way to auto fit in Excel:.

In most situations, the Excel AutoFit feature works without a hitch. There are times, however, when it fails to auto size columns or rows, especially when the Wrap Text feature is enabled. Here's a typical scenario: you set the desired column width, turn Text Wrap on, select the cells of interest, and double click a row separator to autofit the row height. In most cases, rows are sized properly.

But sometimes and this may happen in any version of Excel to Excelsome extra space appears below the last line of text as show in the screenshot below.At the moment if you have a text input control set to multiline, there is no easy way to make the text input box grow and shrink in height to accomodate the text entered. All that happens if you enter more text is that a scrollbar appears. What is required is a "AutoHeight" property. Ah, good idea--kudos. I actually have a work around for this one in the mean time.

It is particularly important for mobile devices that do not have as much screen space. Big idea: use a label's autoheight property and text content to benefit other controls that don't already have it.

I followed your work around, however when I set the label. I was able to replicate your issue when I made the label control hidden. As this is a work around and not a permanent solution, I suggest going with the other method of covering the label with the text input control.

Another method would be to make the text color of the label to RGBA 0, 0, 0, 0 so that it is transparent. This workaround is great but it requires double the controls, which seems to potentially create a performance hit for the app especially if used repeatedly or in a gallery.

Actual support for TextInput. AutoHeight would still be an excellent feature. Its been "under review" since May It would be an invaluable feature. Skip to main content. Turn on suggestions.

Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Showing results for.While I was working on a simple web based markdown editor I needed something where the users can type their texts. My first thought was to use a DIV with the contenteditable attribute.

But it introduced many problems, which I did not want to fight.

But also textareas have a big problem: they have a fixed height per default. You can either set the rows attribute to tell how many rows should be displayed, or you can set their style.

A SIMPLE BUT PIXEL PERFECT SOLUTION

But unfortunately there is no auto-height property. After every change in the text we have to measure how high the content is. Fortunately there is a method to do it. To be able to decrease the size we set the height each time back to zero so that scrollHeight reports the required minimum and not more. We also have to calculate the size of the border and outline, so that we don't give any chance for the content to be cut off, or that a scrollbar is shown.

To do this every time, we use the oninput event, which is fired every time the text content changes. Contrary to onchange which only fires when the users clicks away. Every keypress causes repaints. Because we set the height of the textarea to 0 and then to the calculated value. This should however be negligible, because most users can only type at most a few characters a second.

Therefore it shouldn't cause any noticeable performance drawbacks. Do you like it? Do you already use it?

The dark mode beta is finally here. Change your preferences any time. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. This is my code and it is not working. I want a text input field with a dynamically changing width, so that the input field fluids around its contents. Every input has a built-in padding of 2emthat is the problem and second problem is that min-width ain't working on input at all.

If I set width more than it is needed than the whole program is messy, I need the width of 1px, more only if it's needed. It sounds like your expectation is that the style be applied dynamically to the width of the textbox based on the contents of the textbox.

If so you will need some js to run on textbox contents changing, something like this :. In modern browser versions, CSS unit ch is also available. To my understanding, it is font-independent unit, where 1ch equals to width of character 0 zero in any given font. To calculate the width of the current input, you'll have to embed it in a temporary span element, attach that thing to the DOM, get the computed width in pixels using the scrollWidth property and remove the span again.

Of course you'll have to ensure that the same font family, font size, etc. Therefore I assigned the same class to them. I attached the function to the keyup event, as on keypress the input character is not yet added to the input valueso that will result in the wrong width. Unfortunately, I don't know how to get rid of the scrolling of the input field when adding characters to the end of the field ; it scrolls, because the character is added and shown before adjustWidthOfInput is called.

And, as said, I can't do this the other way round because then you'll have the value of the input field before the pressed character is inserted. I'll try to solve this issue later. It also allows for any number of input fields! Here is a solution without monospaced font needed, with only very small piece code of javascriptdo not need calculate computed stylesand, even support imesupport rtl texts.

Use the span. Copy value of input to the span every time it changed you may change this piece of code to vanilla js easily. So the input will just "fit" the size of its content.
