How do I change the presentation of the "title" attribute in the browser?. By default, it just has yellow background and small font. I would like to make it bigger and change the background color.
Is there a CSS way to style the title attribute?
It seems that there is in fact a pure CSS solution, requiring only the css attr expression, generated content and attribute selectors (which suggests that it works as far back as IE8):
https://jsfiddle.net/z42r2vv0/2/
a {
position: relative;
display: inline-block;
margin-top: 20px;
}
a[title]:hover::after {
content: attr(title);
position: absolute;
top: -100%;
left: 0;
}
<a href="http://www.google.com/" title="Hello world!">
Hover over me
</a>
update w/ input from #ViROscar: please note that it's not necessary to use any specific attribute, although I've used the "title" attribute in the example above; actually my recommendation would be to use the "alt" attribute, as there is some chance that the content will be accessible to users unable to benefit from CSS.
update again I'm not changing the code because the "title" attribute has basically come to mean the "tooltip" attribute, and it's probably not a good idea to hide important text inside a field only accessible on hover, but if you're interested in making this text accessible the "aria-label" attribute seems like the best place for it: https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Techniques/Using_the_aria-label_attribute
You can't style an actual title attribute
How the text in the title attribute is displayed is defined by the browser and varies from browser to browser. It's not possible for a webpage to apply any style to the tooltip that the browser displays based on the title attribute.
However, you can create something very similar using other attributes.
You can make a pseudo-tooltip with CSS and a custom attribute (e.g. data-title)
For this, I'd use a data-title attribute. data-* attributes are a method to store custom data in DOM elements/HTML. There are multiple ways of accessing them. Importantly, they can be selected by CSS.
Given that you can use CSS to select elements with data-title attributes, you can then use CSS to create :after (or :before) content that contains the value of the attribute using attr().
Styled tooltip Examples
Bigger and with a different background color (per question's request):
[data-title]:hover:after {
opacity: 1;
transition: all 0.1s ease 0.5s;
visibility: visible;
}
[data-title]:after {
content: attr(data-title);
background-color: #00FF00;
color: #111;
font-size: 150%;
position: absolute;
padding: 1px 5px 2px 5px;
bottom: -1.6em;
left: 100%;
white-space: nowrap;
box-shadow: 1px 1px 3px #222222;
opacity: 0;
border: 1px solid #111111;
z-index: 99999;
visibility: hidden;
}
[data-title] {
position: relative;
}

Known issues
Unlike a real title tooltip, the tooltip produced by the above CSS is not, necessarily, guaranteed to be visible on the page (i.e. it might be outside the visible area). On the other hand, it is guaranteed to be within the current window, which is not the case for an actual tooltip.
In addition, the pseudo-tooltip is positioned relative to the element that has the pseudo-tooltip rather than relative to where the mouse is on that element. You may want to fine-tune where the pseudo-tooltip is displayed. Having it appear in a known location relative to the element can be a benefit or a drawback, depending on the situation.
You can't use :before or :after on elements which are not containers
There's a good explanation in this answer to "Can I use a :before or :after pseudo-element on an input field?"
Effectively, this means that you can't use this method directly on elements like <input type="text"/>, <textarea/>, <img>, etc. The easy solution is to wrap the element that's not a container in a <span> or <div> and have the pseudo-tooltip on the container.
Examples of using a pseudo-tooltip on a <span> wrapping a non-container element:
[data-title]:hover:after {
opacity: 1;
transition: all 0.1s ease 0.5s;
visibility: visible;
}
[data-title]:after {
content: attr(data-title);
background-color: #00FF00;
color: #111;
font-size: 150%;
position: absolute;
padding: 1px 5px 2px 5px;
bottom: -1.6em;
left: 100%;
white-space: nowrap;
box-shadow: 1px 1px 3px #222222;
opacity: 0;
border: 1px solid #111111;
z-index: 99999;
visibility: hidden;
}
[data-title] {
position: relative;
}
.pseudo-tooltip-wrapper {
/*This causes the wrapping element to be the same size as what it contains.*/
display: inline-block;
}
Text input with a pseudo-tooltip:<br/>
<span class="pseudo-tooltip-wrapper" data-title="input type="text""><input type='text'></span><br/><br/><br/>
Textarea with a pseudo-tooltip:<br/>
<span class="pseudo-tooltip-wrapper" data-title="this is a textarea"><textarea data-title="this is a textarea"></textarea></span><br/>
From the code on the blog post linked above (which I first saw in an answer here that plagiarized it), it appeared obvious to me to use a data-* attribute instead of the title attribute. Doing so was also suggested in a comment by snostorm on that (now deleted) answer.
Here is an example of how to do it:
a.tip {
border-bottom: 1px dashed;
text-decoration: none
}
a.tip:hover {
cursor: help;
position: relative
}
a.tip span {
display: none
}
a.tip:hover span {
border: #c0c0c0 1px dotted;
padding: 5px 20px 5px 5px;
display: block;
z-index: 100;
background: url(../images/status-info.png) #f0f0f0 no-repeat 100% 5%;
left: 0px;
margin: 10px;
width: 250px;
position: absolute;
top: 10px;
text-decoration: none
}
Link<span>This is the CSS tooltip showing up when you mouse over the link</span>
CSS can't change the tooltip appearance. It is browser/OS-dependent. If you want something different you'll have to use Javascript to generate markup when you hover over the element instead of the default tooltip.
I have found the answer here: http://www.webdesignerdepot.com/2012/11/how-to-create-a-simple-css3-tooltip/
my own code goes like this, I have changed the attribute name, if you maintain the title name for the attribute you end up having two popups for the same text, another change is that my text on hovering displays underneath the exposed text.
.tags {
display: inline;
position: relative;
}
.tags:hover:after {
background: #333;
background: rgba(0, 0, 0, .8);
border-radius: 5px;
bottom: -34px;
color: #fff;
content: attr(data-gloss);
left: 20%;
padding: 5px 15px;
position: absolute;
z-index: 98;
width: 350px;
}
.tags:hover:before {
border: solid;
border-color: #333 transparent;
border-width: 0 6px 6px 6px;
bottom: -4px;
content: "";
left: 50%;
position: absolute;
z-index: 99;
}
<a class="tags" data-gloss="Text shown on hovering">Exposed text</a>
I thought i'd post my 20 lines JavaScript solution here. It is not perfect, but may be useful for some depending on what you need from your tooltips.
When to use it
Automatically styles the tooltip for all HTML elements with a TITLE attribute defined (this includes elements dynamically added to the document in the future)
No Javascript/HTML changes or hacks required for every tooltip (just the TITLE attribute, semantically clear)
Very light (adds about 300 bytes gzipped and minified)
You want only a very basic styleable tooltip
When NOT to use
Requires jQuery, so do not use if you don't use jQuery
Bad support for nested elements that both have tooltips
You need more than one tooltip on the screen at the same time
You need the tooltip to disappear after some time
The code
// Use a closure to keep vars out of global scope
(function () {
var ID = "tooltip", CLS_ON = "tooltip_ON", FOLLOW = true,
DATA = "_tooltip", OFFSET_X = 20, OFFSET_Y = 10,
showAt = function (e) {
var ntop = e.pageY + OFFSET_Y, nleft = e.pageX + OFFSET_X;
$("#" + ID).html($(e.target).data(DATA)).css({
position: "absolute", top: ntop, left: nleft
}).show();
};
$(document).on("mouseenter", "*[title]", function (e) {
$(this).data(DATA, $(this).attr("title"));
$(this).removeAttr("title").addClass(CLS_ON);
$("<div id='" + ID + "' />").appendTo("body");
showAt(e);
});
$(document).on("mouseleave", "." + CLS_ON, function (e) {
$(this).attr("title", $(this).data(DATA)).removeClass(CLS_ON);
$("#" + ID).remove();
});
if (FOLLOW) { $(document).on("mousemove", "." + CLS_ON, showAt); }
}());
Paste it anywhere, it should work even when you run this code before the DOM is ready (it just won't show your tooltips until DOM is ready).
Customize
You can change the var declarations on the second line to customize it a bit.
var ID = "tooltip"; // The ID of the styleable tooltip
var CLS_ON = "tooltip_ON"; // Does not matter, make it somewhat unique
var FOLLOW = true; // TRUE to enable mouse following, FALSE to have static tooltips
var DATA = "_tooltip"; // Does not matter, make it somewhat unique
var OFFSET_X = 20, OFFSET_Y = 10; // Tooltip's distance to the cursor
Style
You can now style your tooltips using the following CSS:
#tooltip {
background: #fff;
border: 1px solid red;
padding: 3px 10px;
}
A jsfiddle for custom tooltip pattern is Here
It is based on CSS Positioning and pseduo class selectors
Check MDN docs for cross-browser support of pseudo classes
<!-- HTML -->
<p>
<a href="http://www.google.com/" class="tooltip">
I am a
<span> (This website rocks) </span></a> a developer.
</p>
/*CSS*/
a.tooltip {
position: relative;
}
a.tooltip span {
display: none;
}
a.tooltip:hover span, a.tooltip:focus span {
display:block;
position:absolute;
top:1em;
left:1.5em;
padding: 0.2em 0.6em;
border:1px solid #996633;
background-color:#FFFF66;
color:#000;
}
Native tooltip cannot be styled.
That being said, you can use some library that would show styles floating layers when element is being hovered (instead of the native tooltips, and suppress them) requiring little or no code modifications...
You cannot style the default browser tooltip. But you can use javascript to create your own custom HTML tooltips.
a[title="My site"] {
color: red;
}
This also works with any attribute you want to add for instance:
HTML
<div class="my_class" anything="whatever">My Stuff</div>
CSS
.my_class[anything="whatever"] {
color: red;
}

I have a little issue with my context menu, the CSS doesn't apply and the event on click doesn't work too. If i inspect the element with F12 (on IE 11), I can see the CSS is on the page (in the header) and I can see that all line of the context menu have the event on click but it doesn't work when I click.
CSS :
.ctxmenu
{
position: absolute;
height: auto;
padding: 0px;
margin: 0;
margin-left: 0.5em;
margin-top: 0.5em;
border: 1px solid black;
background: #F8F8F8;
z-index: 11;
overflow: visible;
}
.ctxline
{
display: block;
margin: 0px;
padding: 2px 2px 2px 8px;
border: 1px solid #F8F8F8;
overflow: visible;
}
.ctxline:hover
{
border: 1px solid #BBB;
background-color: #F0F0F0;
background-repeat: repeat-x;
}
for the constitution of the contextMenu :
for (i = 0; i < listCorrection.length; ++i) {
var p = document.createElement('p');
d.appendChild(p);
p.setAttribute('class', 'ctxline');
p.setAttribute('onclick', 'alert("do something");');
p.innerText = listCorrection[i];
}
when I inspect the element of this context Menu i can see :
<p onclick="alert("do something");" class="ctxline">set</p>
and the div containing the context Menu :
<div id="ctxmenu1" style"CURSOR: pointer" class="ctxmenu">(the p on context menu are here)</div>
does anybody have an idea why ? i try to moove it Inside the header with a but it is still not working.
Well after several hours spend on this issue i might have find a fix, if someday someone end up on this page try this :
replace every line that are like this :
p.setAttribute('class', 'ctxline');
by something like this :
p.className = 'ctxline';
I know it's the same thing, but well IE so sometimes you have to think outside the box (this fix work for IE11, IE9, I did not test with other Navigator).
I am using Tipped plugin for tooltip..as I have used a plugin before that is ace admin plugin and Tipped but the problem is it doesnot adjust position according to window size..In free tipped version some functionalities are not there..
Main problem I am getting is I have set tooltip on load and after checking condition I am try to change it but it shows both tooltip
Code :
var a=document.createElement('a');
a.setAttribute('id','23_34');
a.setAttribute('title', 'Transcription ID: ');
if (data == true) {
Tipped.remove("#23_45");
Tipped.create("#23_45", $('<p/>').html('Transcription ID:
}
and it shows both tooltip doesnot remove 1st one..any one have solution or suggest me any tooltip that automatic adjust it position according to window height?
If you dont want to use any plugin for tooltips and just CSS this answer could help.

This question already has answers here:
Selecting and manipulating CSS pseudo-elements such as ::before and ::after using javascript (or jQuery)
(26 answers)
Closed 5 years ago.
Markup:
<h1 class="title">Hello World</h1>
CSS:
.title {
border-bottom: 3px solid #aaa;
position: relative;
}
.title:after {
content: "";
width: 100px;
border-bottom: 3px solid red;
display: block;
position: absolute;
}
Demo: http://codepen.io/anon/pen/HDBqe
I wanted to change the .title:after's width based on the text's width, how do I change :after's width using javascript?
$.fn.textWidth = function(){
var html_org = $(this).html();
var html_calc = '<span>' + html_org + '</span>';
$(this).html(html_calc);
var width = $(this).find('span:first').width();
$(this).html(html_org);
return width;
};
$('.title').each(function(){
// Change :after's width based on the text's width
// .css('width', $(this).textWidth());
});
I've found a trick which works in this case. I've updated your demo:
http://codepen.io/anon/pen/bHLtk
.title {
border-bottom: 3px solid #aaa;
position: relative;
min-width: 100%;
}
.title:after {
content: "";
width: inherit;
border-bottom: 3px solid red;
display: block;
position: absolute;
}
Notice, that .title:after has width set to inherit but his parent (.title) has overridden width with min-width. Now I can freely to set width by JavaScript to title and it take effect only on his nested pseudoelement:
$('.title').each(function(){
$(this).css('width', $(this).textWidth());
});
A pseudo-element is not part of the DOM. Therefore, you cannot change its CSS properties directly through JS.
In order to get your desired effect the way you want it, my best guess would be YUI.StyleSheet and manipulate the stylesheet itself, although I have to admit I haven't tested it myself in recent years.
Including such a utility and doing all of this calculation seems like a lot of work for width matching.
If you are willing to compromise a little bit on the semantic HTML, there is a working technique:
Your element takes the entire width of the screen. Wrapping the text with a span and adding the pseudo-element to that, as an inline-block should allow you to get the border under the text only
HTML:
<h1 class="title"><span>Hello World</span></h1>
CSS:
.title {
border-bottom: 3px solid #aaa;
position: relative;
}
.title span{
display:inline-block;
position:relative;
}
.title span:after {
content: "";
width: 100%;
border-bottom: 3px solid red;
display: block;
position: absolute;
}
Here is my version of the codePen.
For future reference:
There is a W3C Candidate Recommendation that suggests the capability of using attributes for CSS properties other than content.
This way, if and when the recommendation is approved and implemented, it might be possible to have the pseudo-element reflect the parent's attributes, as such:
this.setAttribute("length", $(this).textWidth());
And the relevant CSS:
.title:after {
...
width: attr(length px);
...
}
How's this for a different approach.... http://jsfiddle.net/mayYt/
Added CSS
.title span {
border-bottom: 3px solid red;
}
JQuery
$('.title').wrapInner('<span />');
With just a simple trick any pseudo-element can be changed (or at least replaced with something else):
$('.something').click(function(){
$(this).toggleClass('to_show');
});
.something
{
background: red;
height: 40px;
width: 120px;
position: relative;
}
.something.to_show:after
{
content: "X";
color: white;
background: green;
width: 20px;
height: 20px;
position: absolute;
right: 0px;
top: 0px;
display: block;
text-align: center;
}
.something:after
{
content: "O";
color: white;
background: blue;
width: 30px;
height: 25px;
position: absolute;
right: 0px;
top: 0px;
display: block;
text-align: center;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<html>
<body>
<div class="something">
click here!
</div>
</body>
</html>
I'm not sure if what i want is possible but i'm using a Mootools image gallery which you can see an example of here:
</script>
function startGallery() {
var myGallery = new gallery($('myGallery'), {
timed: true,
showArrows: false,
showCarousel: false
});
}
window.addEvent('domready', startGallery);
</script>
The gallery rotation is above but what i'd like to achieve, ideally, is the second text element (with the white background) to be wider than the top text element, so it looks more like the picture underneath.
There's a lot of Javascript involved so i don't know what i should post here to enable people to help, but just let me know what i should put in here and i'll come back and edit.
Or, if some knows of somethign similar in jQuery which would allow me to get the same effect, but not require too much JS coding, i'd be much obliged.
Thanks in advance as always,
Dan
Try this css and see if its what your after.
.slideInfoZone {
position: absolute;
z-index: 10;
width: 100%;
margin: 0px;
left: 0;
top:40px;
color: #FFF;
text-indent: 0;
overflow: hidden;
padding: 10px 0 0 20px;
height: 70px;
}
.slideInfoZone h3{
background: #000;
width: 200px;
padding: 30px;
margin-left: -30px;
display:inline;
}
.slideInfoZone p {
position: absolute;
bottom: 0;
background: #FFF;
font-size: 14px;
color: #000;
margin: 20px 0 0 -20px;
padding: 10px 0 10px 20px;
width: 50%;
}
Basically what I did was remove your background color for the containing element, then I gave the p tag a bg color, and modified the padding/margin for the h3. Im not too happy with what I had to do with the h3 but without changing the markup at all it works.
