Most Elegant Way to Force a Textarea Element to Line-Wrap, *Regardless* of Whitespace

Most elegant way to force a TEXTAREA element to line-wrap, regardless of whitespace

The CSS settings word-wrap:break-word and text-wrap:unrestricted appear to be CSS 3 features. Good luck finding a way to do this on current implementations.

Internet Explorer 11 word wrap is not working

In order to ensure that the answer is obvious to people visiting this question in the future: the OP (wesley) answered the question himself in the comments beneath the question:

The cause of the problem is that Internet Explorer 11 makes textarea elements inherit whatever white-space property is applied to the direct parent.

The resolution is to apply white-space: pre-wrap to the textarea, as identified by Jean-François Beauchamp.

wordwrap for textarea using javascript or jquery

function charCountTextarea(textAreaId,e,limit,lineLen)
{   

    var code = e.charCode || e.keyCode;

    newLines = $("#"+textAreaId).val().split("\n").length;
    var t = $("#"+textAreaId)[0];
    var lineIndex = t.value.substr(0, t.selectionStart).split("\n").length-1;
    console.log('val t :'+$("#"+textAreaId).val()+' line index : '+lineIndex+' new lines '+newLines);

    if(lineIndex == 10 && $("#"+textAreaId).val().split("\n")[lineIndex].length>(lineLen+1) && code!=8 && code!=46 && code!=33 && code!=34 && code!=35 && code!=36 && code!=37 && code!=38 && code!=39 && code!=40)
    {
        $("#"+textAreaId).val(($("#"+textAreaId).val()).substring(0, $("#"+textAreaId).val().length - 1));
        alert('You are reached to limit');
        return false;
    }

    if(lineIndex<5)
    {
        $("#"+textAreaId).val($("#"+textAreaId).val().wordWrap(lineLen, "\n", 0));
    }
    var countLine1 = $("#"+textAreaId).val().split("\n")[0].length;

    if($("#"+textAreaId).val().split("\n")[lineIndex].length>lineLen)  // which will count the total line char condition
    {
        console.log("In condition : ");
        if(code!=8 && code!=46 && code!=33 && code!=34 && code!=35 && code!=36 && code!=37 && code!=38 && code!=39 && code!=40)
        {
            // to insert next line              
            insertTextAtCaret(document.getElementById(textAreaId), "\n");
        }
    }
}

Textarea to resize based on content length

You can check the content's height by setting to 1px and then reading the scrollHeight property:

function textAreaAdjust(element) {
  element.style.height = "1px";
  element.style.height = (25+element.scrollHeight)+"px";
}

<textarea onkeyup="textAreaAdjust(this)" style="overflow:hidden"></textarea>

How to remove the space between inline/inline-block elements?

Alternatively, you should now use flexbox to achieve many of the layouts that you may previously have used inline-block for: https://css-tricks.com/snippets/css/a-guide-to-flexbox/

Since this answer has become rather popular, I'm rewriting it significantly.

Let's not forget the actual question that was asked:

How to remove the space between inline-block elements? I was hoping
for a CSS solution that doesn't require the HTML source code to be
tampered with. Can this issue be solved with CSS alone?

It is possible to solve this problem with CSS alone, but there are no completely robust CSS fixes.

The solution I had in my initial answer was to add font-size: 0 to the parent element, and then declare a sensible font-size on the children.

This works in recent versions of all modern browsers. It works in IE8. It does not work in Safari 5, but it does work in Safari 6. Safari 5 is nearly a dead browser (0.33%, August 2015).

Most of the possible issues with relative font sizes are not complicated to fix.

However, while this is a reasonable solution if you specifically need a CSS only fix, it's not what I recommend if you're free to change your HTML (as most of us are).

This is what I, as a reasonably experienced web developer, actually do to solve this problem:

<p>
    <span>Foo</span><span>Bar</span>
</p>

Yes, that's right. I remove the whitespace in the HTML between the inline-block elements.

It's easy. It's simple. It works everywhere. It's the pragmatic solution.

You do sometimes have to carefully consider where whitespace will come from. Will appending another element with JavaScript add whitespace? No, not if you do it properly.

Let's go on a magical journey of different ways to remove the whitespace, with some new HTML:

<ul>
    <li>Item 1</li>
    <li>Item 2</li>
    <li>Item 3</li>
</ul>

You can do this, as I usually do:

 <ul>
     <li>Item 1</li><li>Item 2</li><li>Item 3</li>
 </ul>

http://jsfiddle.net/thirtydot/dGHFV/1362/

Or, this:

 <ul>
     <li>Item 1</li
     ><li>Item 2</li
     ><li>Item 3</li>
 </ul>

Or, use comments:

 <ul>
     <li>Item 1</li><!--
     --><li>Item 2</li><!--
     --><li>Item 3</li>
 </ul>

Or, if you are using using PHP or similar:

 <ul>
     <li>Item 1</li><?
     ?><li>Item 2</li><?
     ?><li>Item 3</li>
 </ul>

Or, you can even skip certain closing tags entirely (all browsers are fine with this):
```
 <ul>
     <li>Item 1
     <li>Item 2
     <li>Item 3
 </ul>
```

Now that I've gone and bored you to death with "one thousand different ways to remove whitespace, by thirtydot", hopefully you've forgotten all about font-size: 0.

React: how to make an input only as wide as the amount of text provided?

Here is an approach from plain HTML/CSS and a working snippet , hidding the value typed inside a span behind the input set in an absolute position. CSS can make both span and input matching the same lenght/width. Stretching/collapsing a parent (label) will finish the job.

In the courtesy of @silvenon you may also find a react sample below the snippet

var val = document.querySelector('#test');
let tpl = document.querySelector('#tpl');
let text = val.value;
 tpl.textContent= text;

val.addEventListener("input", function () {// onchange ...
  let text= val.value;
  //console.log(text);
  tpl.textContent= text;
  });

label {
  display: inline-block;
  position: relative;
  min-width: 2em;
  min-height: 1.4em;
}

#tpl {
  white-space: pre;
  /* max-width : could be wised to set a maximum width and overflow:hidden; */
}

#test {
  font-family: inherit;
  font-size: inherit;
  position: absolute;
  vertical-align: top;
  top: 0;
  left: 0;
  width: 100%;
  background: white;
}

<label><span id="tpl"></span><input id='test' value="Some test to try" ></label>
