问题:

Is there a way to automatically justify words using letter spacing, each in its row, to a defined width, using CSS?

For example, "Something like this" would look, well, something like this:

Is there a non-obtrusive way to apply such styling to my text? I believe pure CSS doesn't have this option (at least not with CSS versions before 3, CSS3 seems to have a text-justify property, but it's not well supported yet), so js solutions would be fine also.

Here's a script which can do it. It isn't pretty, but maybe you can hack it to meet your needs. (Updated to handle resizing)

<html>
<head>
<style>
#character_justify {
    position: relative;
    width: 40%;
    border: 1px solid red;
    font-size: 32pt;
    margin: 0;
    padding: 0;
}
#character_justify * {
    margin: 0;
    padding: 0;
    border: none;
}
</style>
<script>
function SplitText(node)
{
    var text = node.nodeValue.replace(/^\s*|\s(?=\s)|\s*$/g, "");

    for(var i = 0; i < text.length; i++)
    {
        var letter = document.createElement("span");
        letter.style.display = "inline-block";
        letter.style.position = "absolute";
        letter.appendChild(document.createTextNode(text.charAt(i)));
        node.parentNode.insertBefore(letter, node);

        var positionRatio = i / (text.length - 1);
        var textWidth = letter.clientWidth;

        var indent = 100 * positionRatio;
        var offset = -textWidth * positionRatio;
        letter.style.left = indent + "%";
        letter.style.marginLeft = offset + "px";

        //console.log("Letter ", text[i], ", Index ", i, ", Width ", textWidth, ", Indent ", indent, ", Offset ", offset);
    }

    node.parentNode.removeChild(node);
}

function Justify()
{
    var TEXT_NODE = 3;
    var elem = document.getElementById("character_justify");
    elem = elem.firstChild;

    while(elem)
    {
        var nextElem = elem.nextSibling;

        if(elem.nodeType == TEXT_NODE)
            SplitText(elem);

        elem = nextElem;
    }
}

</script>
</head>
<body onload="Justify()">
<p id="character_justify">
Something<br/>
Like<br/>
This
</p>
</body>

I know this is an old topic, but I faced this the other night. And found a suitable solution using tables.

Every letter shall be put into a <td> </td> I know it looks tedious, but if you wanna do this, it would be for a word or two, right? Or you always can use JS to fill it if is too much. However, this is only CSS and very versatile solution.

Using letter-spacing the letters get distributed properly. You should play around with it, depending on the width of the table.

#justify {
  width: 300px;
  letter-spacing: 0.5em;
}

<table id="justify">
  <tbody>
    <tr>
      <td>J</td>
      <td>U</td>
      <td>S</td>
      <td>T</td>
      <td>I</td>
      <td>F</td>
      <td>Y</td>
    </tr>
  </tbody>
</table>

See the example here

Crossbrowser safe, virtually nothing shall differ. Is just CSS.

I used it in My website which is in english and spanish. the subtitle under my name in spanish has an additional letter and it will step out the width. Using the tables explained above, it gets distributed to the same width automatically. Spacing it manually I'd had to define a whole condition for each language to go around that.

The css only solution is text-justify: distribute https://www.w3.org/TR/css-text-3/#text-justify but the support is still very poor.

A small experiment using text-align-last: justify and adding spaces between letters. 

div{
	display:inline-block;
	text-align: justify;
	text-align-last: justify;
	letter-spacing: -0.1em;
}
<div>
S o m e t h i n g<br>
l i k e<br>
t h i s
</div>

Here is an other aproach using a jQuery snippet I wrote for this question : Stretch text to fit width of div :

DEMO

HTML :

<div class="stretch">Something</div>
<div class="stretch">Like</div>
<div class="stretch">This</div>

jQuery :

$.fn.strech_text = function () {
    var elmt = $(this),
        cont_width = elmt.width(),
        txt = elmt.html(),
        one_line = $('<span class="stretch_it">' + txt + '</span>'),
        nb_char = elmt.text().length,
        spacing = cont_width / nb_char,
        txt_width;

    elmt.html(one_line);
    txt_width = one_line.width();

    if (txt_width < cont_width) {
        var char_width = txt_width / nb_char,
            ltr_spacing = spacing - char_width + (spacing - char_width) / nb_char;

        one_line.css({
            'letter-spacing': ltr_spacing
        });
    } else {
        one_line.contents().unwrap();
        elmt.addClass('justify');
    }
};


$(document).ready(function () {
    $('.stretch').each(function () {
        $(this).strech_text();
    });
});

Needed this too, so I've bundled the suggested technique in a simple to use jquery-plugin you can find here: https://github.com/marc-portier/jquery-letterjustify#readme.

It uses the same procedure at its core, and adds some options to tweak. Comments welcome.



回答6:

Again, I know this is REALLY old, but why not just put a space between each letter and then text-align:justify? Then each letter would be regarded as a 'word' and justified accordingly

An alternate way to handle this might be to use the "vw" sizing unit. This unit type can be used in font size properties and represents a percent of the window's width.

Disclaimer: It is not exactly what you are looking for, but requires no scripting. It does adjust the text size, but will also scale to the width of your page.

For example, 

.heading {
  font-size: 4vw;
}

will make the width of one character in the current font 4% of the window width.

You could then use media queries if you wish to lock the font size to a minimum size based on the window's width.

@media only screen and (max-width: 768px) {
    font-size: 2rem;
}

Use the browser inspector to play with the font-size property and tweak the value to what makes sense for your application.

The "vw" unit works in IE9+, iOS 8.3+ and Android 4.4+ and all other mainstream browsers. I wouldn't worry about the mobile support too much, as you can use media queries to put the right sizing for these devices as described above.

Viewport units are a powerful way to scale many different aspects of your site with little code.

I just made a JQuery script from table's Tony B approach. Here is the JSFiddle https://jsfiddle.net/7tvuzkg3/7/

This script creates a table with each char in a row. This works with full sentence. I'm not sure this is fully optimized.

justifyLetterSpacing("sentence");

function justifyLetterSpacing(divId) {

	// target element
	domWrapper = $('#' + divId).clone().html('');
	// construct <td>
	$('#' + divId).contents().each(function(index){
      // store div id to td child elements class
	  var tdClass = divId ;
      // split text 
	  $textArray = $(this).text().split('');
      // insert each letters in a <td>
	  for (var i = 0; i < $textArray.length; i++) {
        // if it's a 'space', replace him by an 'html space'
        if( $textArray[i] == " " )  {
            $('<td>')
                .addClass(tdClass)
                .html("&nbsp;&nbsp;")
                .appendTo(domWrapper);
        }// if it's a char, add it
        else{  
            $('<td>')
                .addClass(tdClass)
                .text($textArray[i])
                .appendTo(domWrapper);
        }
	  }
	});
    // create table
    table = 
    $( "<table id='"+divId+"'/>" ).append( 
        $( "<tbody>" ).append( 
            $( "<tr>" ).append( 
                ( domWrapper ).children('td') 
            ) 
        )
    );
    // replace original div
	$('#' + divId).replaceWith( table );
}	
#sentence {
  width : 100%;
  background-color : #000;
  color : #fff;
  padding : 1rem;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="sentence">LOREM IPSUM DOLOR</div>

What is wrong with text-align: justify? I think I might be misunderstanding your question.
