I'm currently adding verbose tooltips to our site, and I'd like (without having to resort to a whizz-bang jQuery plugin, I know there are many!) to use carriage returns to format the tooltip.
To add the tip I'm using the title attribute. I've looked around the usual sites and using the basic template of:
<a title='Tool?Tip?On?New?Line'>link with tip</a>
I've tried replacing the ? with:
<br />&013; / \r\nEnvironment.NewLine (I'm using C#)None of the above works. Is it possible?
The latest specification allows line feed characters, so a simple line break inside the attribute or entity (note that characters # and ; are required) are OK.
It’s simple: just press Enter!
<a href="#" title='Tool
Tip
On
New
Line'>link with tip</a>Try character 10. Until January 2015 it wouldn't work in Firefox.
The text is displayed (if at all) in a browser dependent manner. Small tooltips work on most browsers. Long tooltips and line breaking work in IE and Safari (use
or for a new newline). Firefox and Opera do not support newlines. Firefox does not support long tooltips.

Firefox now supports using to insert a line break in an HTML title attribute. See the snippet example below.
<a href="#" title="Line 1 Line 2 Line 3">Hover for multi-line title</a>On Chrome 79, does not work anymore.
I was successful with:
This works in all major browsers.
I don't believe it is. Firefox 2 trims long link titles anyway and they should really only be used to convey a small amount of help text. If you need more explanation text I would suggest that it belongs in a paragraph associated with the link. You could then add the tooltip JavaScript code to hide those paragraphs and show them as tooltips on hover. That's your best bet for getting it to work cross-browser IMO.
Much nicer looking tooltips can be created manually and can include HTML formatting.
<!DOCTYPE html>

<body style="text-align:center;">
<h2>Tooltip</h2>
<p>Move the mouse <a href="#" title="some text
more and then some">over</a> the text below:</p>
<div class="tooltip">Hover over me
<span class="tooltiptext">Tooltip text
some <b>more</b><br/>

This is taken from the W3Schools post on this. Experiment with the above code here.
There are multiple ways to do this. 
 or 
 depending on the browser. But the following example works for me on my Google Chrome and Firefox.
<a href="javascript:;" title="Tooltip Line One Tooltip Line Two Tooltip Line Three">Tooltip</a>Using \x0A worked for me to get newline in title/tooltip on mouse hover.
FILENAME: news.php
<span onmouseover="getInfo(this,'06-APR-22')" data-html="true">Day</span>
FILENAME: news.php
<script>
function getInfo(x, dateVal) {
var html = $.ajax({
type: "POST",
url: "report/get-info.php",
data: {
'dateVal': dateVal,
},
success: function(response) {
x.setAttribute('title', response );
}
});
}
</script>
FILENAME: get-info.php
<?php
$tmp = $_POST['dateVal'];
$dateVal = date("m/d/Y", strtotime($tmp));
$querySelectCode = "SELECT INFO_ID, INFO_NAME FROM INFORMATION
WHERE TRUNC(DP.DATE_TIME) = TO_DATE('$dateVal','MM/DD/YYYY') ";
$stmtSelectcode = oci_parse($dbConn, $querySelectCode);
if ( ! oci_execute($stmtSelectcode) ){
$err = oci_error($stmtSelectcode);
trigger_error('Query failed: ' . $err['message'], E_USER_ERROR);
}
$INFO_ID = array();
while(oci_fetch($stmtSelectcode)){
$INFO_ID[] = oci_result($stmtSelectcode, 'INFO_ID');
$INFO_NAME[] = oci_result($stmtSelectcode, 'INFO_NAME');
}
for($index=0 ; $index < count($INFO_ID) ; $index++)
{
echo $INFO_NAME[$index ] . "\x0A" ;
}
?>
I have tried with to display the title text on a new line and it’s working like a charm.
I am on Firefox 68.7.0 ESR and the 
 doesn't work. Breaking the lines via <CR> did work, so I am going with that since it simple and forward.
I.e.,
<option title="Constraint PSC/SCS/Activity
Definition Constraint Checker
Database Start Notifier">CnCk
The "just press enter" solution didn't work here, so the good old vanilla JavaScript seems a pretty efficient and clean way.
function customTitle(event, textHeader, text){
let eventOrigin = event.target || event.srcElement;
eventOrigin.title = textHeader + '\n\n' + text;
}
And on element onmouseover:
onmouseover="customTitle(event, 'Some Caput', 'Some more or less complete description');"
Voilà! It works on Google Chrome and Firefox (which does not exclude others; I just didn't check it).
If you are trying to do this in a React project where you are rendering in the below format:
title={`First line of text ${varOne} Second line of text ${varTwo} Third line of text ${varThree}`}
Then , and similar solutions don't work. They will actually render as text.
Instead actually creating the text as required is a better option. An example for better understanding:
title={`First line of text ${varOne}
Second line of text ${varTwo}
Third line of text ${varThree}`}
Make sure to remove tabs/space indentations before "Second line of text" and "Third line of text". Otherwise they will render as well.
It was tested on Google Chrome 96 and Firefox 95.0b12 (Developer Edition, because, well why not). It should work on most modern browsers as well.
I was directed to this page while searching for a solution to display breakline in Bootstrap tooltips. Bootstrap tooltips are displayed when data-toggle="tooltip" is added to a HTML tag.
Finally, I found out that a data-html="true" should be added to the tag, and doing so the HTML inside your title will be rendered. Then use <br> to breakline. Checkout the samples below:
Before (not showing any breakline):
<i class="bi bi-x-circle" data-toggle="tooltip" data-placement="top" title="test1 <br> test2"></i>
After (showing breakline):
<i class="bi bi-x-circle" data-toggle="tooltip" data-html="true" data-placement="top" title="test1 <br> test2"></i>
- Tip for Laravel and Blade programmers: You can convert \n to <br> with nl2br("string") function.
- The solutions above have been tested in Google Chrome 98.
Just sharing small bug I saw:
In Chrome 103 with this html:
<!DOCTYPE html>
<html>
<body>
<select title="Line 1 : Line 2">
<option value="0">test</option>
</select>
</body>
</html>I see this:
On screenshot - two weird characters after "Line 1 :" text, first line.
Fix to this: (I have no idea which is correct/valid but all of them works as fix (in Chrome 103))
Line 1 : before first fix it to full line title="Line 1 : Line 2" after Line 1 : before first to "Carriage Return symbol" will fix it
