Css text overflow ellipsis 2 lines

CSS многоточие после нескольких строк

В CSS очень просто обрезать текст в одной строке для некоторой ширины и отобразить многоточие.

text-overflow: ellipsis; white-space: nowrap; overflow: hidden; width: 300px;

Но все не так просто, если надо обрезать текст после трёх (нескольких) строк. Это можно сделать с помощью javascript, но это будет не самое элегантное решение. Есть другой простой способ – использовать CSS-свойство line-clamp .

CSS-свойство line-clamp помогает подрезать текст на определенное количество строк.

Синтаксис

line-clamp может принимать следующие значения:

• none : не устанавливает ограничение, подрезания строк не будет.
• : устанавливает максимальное количество строк перед подрезанием содержимого, а затем отображает многоточие (…) в конце последней строки.

А как это сделать с text-overflow ?

Для text-overflow действительно есть значение ellipsis для ограничения текста:

Для начала – нормально. Но что, если надо добавить многоточие не в первой строке, а где-нибудь, скажем, в третьей строке текста?

Вот здесь в игру вступает line-clamp . Надо заметить, что для придётся использовать комбинацию из трех свойств:

Но, есть нюанс…

Это неполная поддержка браузерами. Тут используется префикс -webkit- (который, как ни странно, работает во всех основных браузерах, но это не точно).

Как обычно, уточнить поддержку свойства браузерами можно на странице Caniuse.

Если добавить немного Javascript, например, использовать небольшой скрипт Clamp.js, получится расширить этот список, посмотрите:

CSS Ellipsis for Single-Line and Multi-Line Text

Learn to truncate text and add ellipsis at the end using CSS. For both, single-line and multi-line text.

So your designer has asked you to add the three dots at the end when the text doesn’t fit, and you have no clue how to do that?

Don’t worry, it’s super simple to do with CSS.

By the way, those three dots at the end are called ellipsis.

Real quick — would you like to master CSS and learn Web Development? If so, be sure to check out the platform I recommend to learn coding online:

Single-line ellipsis

Use text-overflow: ellipsis; to automatically truncate the text when it overflows the container and add the three dots at the end.

The element needs to get resized and the text has to stay in one line for the ellipsis to show up, so here are all 3 CSS lines you need:

Multi-line ellipsis

You will soon find, that text-overflow: ellipsis; doesn’t work when the text wraps to an extra line.

To truncate multi-line text and add an ellipsis at the end of the last line use the experimental -webkit-box box model (don’t worry it’s supported in all major browsers):

Conclusion

It’s trivial to truncate the overflowing text and add an ellipsis at the end of a single line. Adding an ellipsis for multiline text is a bit more tricky, so this post should help you.

How to make Ellipsis to multiline text in CSS

Kiran Acharya / December 30, 2020 / CSS, Front-End

Showing 1 or 2 lines of the title looks good on designs like card or excerpt, also important to handle the extra text overflowing in the same line.

UI Developers usually truncate the extra text in the line by applying text-ellipsis, which means showing the 3 dots (visually explains there is even more text, that can be handled by applying title attribute to the element and show the full text on hover).

Ellipsis to one line text

Applying ellipsis for one like is easy. Requires just 3 line of CSS. Follow the code below.

Ellipsis to multiline text

Same way you can apply for 3 or more lines by modifying the -webkit-line-clamp value.

Bootstrap 4

Bootstrap 4 has an inbuilt class for 1 line ellipsis, text-truncate. For multiline text-truncate add a separate style just like the below code.

.text-truncate.text-truncate--2

Hope this article helped you. Thank you.

Pure CSS for multiline truncation with ellipsis

BLOG UPDATE (updated on Nov 2018):
Hacking UI was founded by us – David Tintner and Sagi Shrieber – but since then we each have gone down our own paths, and would love to invite you there.

David is now working full time on Thoughtleaders – a marketplace for higly targeted content-marketing solutions for bloggers and brands.

There he teaches and gives free tips and strategies on how to build an online brand, and make it into a business while hosting a weekly podcast interviewing some of the world’s most inspiring online entrepreneurs. You can subscribe to the podcast on iTunes, Youtube, Spotify, or your favorite podcast app.

As of today, this is what we – David and Sagi – are doing FULL TIME.

CSS3 gave us the wonderful property, text-overflow , which can do things like create ellipsis and gracefully cut off words. However, text-overflow has a serious limitation: it only works on a single line of text.

A few days ago I had to truncate a multiline block of text. It’s a common problem, but I was a disappointed because we still don’t have a simple, cross-browser CSS solution for it. I tried a few ideas, but each time I found that the ‘…’ wasn’t quite right. Sometimes it appeared far from the end of the text or fell over to the next line.

Finally I found the ideal solution.

What are the options?

In order to fully understand why this pure CSS solution is so awesome, I want to run through a few of the alternatives and the problems with each.

If you’d like, you can jump ahead to check out a live example of the solution: codepen demo.

1. -Webkit-line-clamp property

I really like this for it’s simplicity, but unfortunately it is not cross browser (doesn’t work in Firefox and Internet Explorer). I hope that in future we will have a regular, non-vendor-prefixed CSS property.

To use -webkit-line-clamp, add the following to your CSS:

2. Text-overflow: -o-ellipsis-lastline

As of version 10.60, Opera added the ability to clip text on multi-line blocks. To be honest I have never tried this property, but it allows you to use -webkit-line-clamp .

3. Using JavaScript

Here’s a simple Javascript function for truncating text, but it has some serious drawbacks.

 function ellipsizeTextBox(id) < var el = document.getElementById(id); var wordArray = el.innerHTML.split(' '); while(el.scrollHeight >el.offsetHeight) < wordArray.pop(); el.innerHTML = wordArray.join(' ') + '. '; >> ellipsizeTextBox(‘block-with-text); 

Some of the drawbacks of this method include requiring the block of text to have a fixed height, not waiting for the font to load and the possibility that the ‘…’ will appear on the next line after the main text.

4. Truncate the text on the server

This is an example of truncating the text in PHP. This method works fine in limiting the text, but requires messing with the server-side just to deal with presentation, which is supposed to the be the job of CSS.

 $text = 'your long long text'; $maxPos = 100; if (strlen($text) > $maxPos)

A Simple, Pure CSS Solution

Clearly none of these options are perfect. I wanted an easier and more bulletproof way to handle this, so I found that we can truncate text using two carefully placed CSS pseudo elements.

Here’s the full CSS. We’ll walk through the code below.

/* styles for '. ' */ .block-with-text < /* hide text if it more than N lines */ overflow: hidden; /* for set '. ' in absolute position */ position: relative; /* use this value to count block height */ line-height: 1.2em; /* max-height = line-height (1.2) * lines max number (3) */ max-height: 3.6em; /* fix problem when last visible word doesn't adjoin right side */ text-align: justify; /* place for '. ' */ margin-right: -1em; padding-right: 1em; >/* create the . */ .block-with-text:before < /* points in the end */ content: '. '; /* absolute position */ position: absolute; /* set position to right bottom corner of block */ right: 0; bottom: 0; >/* hide . if we have text, which is less than or equal to max lines */ .block-with-text:after < /* points in the end */ content: ''; /* absolute position */ position: absolute; /* set position to right bottom corner of text */ right: 0; /* set width and height */ width: 1em; height: 1em; margin-top: 0.2em; /* bg color = bg color under block */ background: white; >

How It Works

Let’s imagine that we need to contain a block of text to a max of 3 lines. In order to do so, we have to handle the following cases:

1. The text is more than 3 lines

2. The text is less than 3 lines

3. The text is exactly 3 lines

Benefits

• 1. Pure CSS
• 2. Responsive
• 3. No need to recalculate on resize or font’s load event
• 4. Cross browser

A couple things to watch out for

Unfortunately this solution also has some drawbacks:

• 1. We need to have a plain background color for covering up the ‘…’ if the text is less than the max number of lines.
• 2. we need some space for ‘…’, and if the parent block has overflow: hidden or overflow: auto then we need to remove style margin-right: -1em; .

Also for the patient reader, I created an SCSS mixin to do this faster:
codepen demo

/* mixin for multiline */ @mixin multiLineEllipsis($lineHeight: 1.2em, $lineCount: 1, $bgColor: white) < overflow: hidden; position: relative; line-height: $lineHeight; max-height: $lineHeight * $lineCount; text-align: justify; margin-right: -1em; padding-right: 1em; &:before < content: '. '; position: absolute; right: 0; bottom: 0; >&:after < content: ''; position: absolute; right: 0; width: 1em; height: 1em; margin-top: 0.2em; background: $bgColor; >> .block-with-text

What do you think? Do you have another solution for multiline text truncation? Let me know in the comments.
