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;
}
See it work at: http://jsfiddle.net/vpYWE/1/
I have a lot of forms on my website with, of course, many of the fields in them being required. If required field is left empty, it is assigned an 'error' class and I'm trying to circle the field in red regardless whether it is a text field, drop down menu or a checkbox.
I have the following code in my css file:
.error input, .error select, .error textarea {
border-style: solid;
border-color: #c00;
border-width: 2px;
}
Now strangely enough that works well in IE but in Chrome the checkboxes are not circled in red although I can see that the CSS is applied to them when inspecting the element.
And this might be irrelevant at the css code above is active but I do have something else in my css file:
input[type=checkbox] {
background:transparent;
border:0;
margin-top: 2px;
}
And that is used so that the checkboxes are displayed correctly in IE8 and less.
Any ideas how I can visualize the red border in Chrome?
EDIT:
Here's a jsfiddle:
http://jsfiddle.net/PCD6f/3/
Just do it like so (your selectors were wrong: .error input, .error select, .error textarea):
input[type=checkbox] {
outline: 2px solid #F00;
}
Here's the jsFiddle
Specifically for a checkbox use outline: 2px solid #F00;, BUT keep in mind that the border will still be visible. Styling input fields to look them well across multiple browsers is tricky and unreliable.
For a completely custom styled checkbox, see this jsFiddle from this Gist.
EDIT Play with: outline-offset: 10px;
Check Box, and Radio Button CSS Styling Border without any image or content. Just pure css.
JSFiddle Link here
input[type="radio"]:checked:before {
display: block;
height: 0.4em;
width: 0.4em;
position: relative;
left: 0.4em;
top: 0.4em;
background: #fff;
border-radius: 100%;
content: '';
}
/* checkbox checked */
input[type="checkbox"]:checked:before {
content: '';
display: block;
width: 4px;
height: 8px;
border: solid #fff;
border-width: 0 2px 2px 0;
-webkit-transform: rotate(45deg);
transform: rotate(45deg);
margin-left: 4px;
margin-top: 1px;
}
Works for me.only outline doesn't work.
input[type=checkbox].has-error{
outline: 1px solid red !important;
}
In Play 2, there's a sample computer-database-jpa supporting the sorting of columns. By default it's sorted by computer, an arrow is indicating the sort order. I need this CSS style / arrow in another project, but even after examining the CSS code for this table header
<th class="name header headerSortDown">
Computer name
</th>>
I still can't see where the arrow is coming from? Any hint on this? Thanks!
Update:
One can browse the CSS here: https://github.com/playframework/Play20/tree/master/samples/java/computer-database-jpa/public/stylesheets
But on e.g. headerSortDown I can't find something that looks like an arrow ):
For a follow up question:
How to get the arrow directly next to the text?
The easiest way is to use inspection tool of your browser (ie FireBug in Firefox or built-in inspector in Chrome)
Here's standalone extract of the arrows, as you can see they are 'drawing' the arrows with CSS border (no image required)
<!DOCTYPE html>
<html>
<head>
<title>Arrows a'la Twitter Bootstrap</title>
<style type="text/css">
.header {
width: 200px;
background-color: #c2ccd1;
padding: 4px;
margin: 2px;
}
.header:after {
content: "";
float: right;
margin-top: 7px;
visibility: hidden;
}
.headerSortDown:after, .header:hover:after {
border-width: 0 4px 4px;
border-style: solid;
border-color: #000 transparent;
visibility: visible;
}
.headerSortUp:after {
border-bottom: none;
border-left: 4px solid transparent;
border-right: 4px solid transparent;
border-top: 4px solid #000;
visibility: visible;
}
</style>
</head>
<body>
<div class="header">Not selected</div>
<div class="header headerSortDown">Arrow up (sorting ASC)</div>
<div class="header headerSortUp">Arrow down (sorting DESC)</div>
</body>
</html>
And here's nice tutorial about drawing triangles with CSS border.
Edit
DIV tag uses a block display so it tries to use full width OR the width given in CSS style (in above sample it's 200px) if you'll use that arrow with some inline element like A or SPAN the arrow will be 'glued' to the text. Of course you can also force displaying DIV as an inline, the simplest way to do that (by modifying sample)
for .header declaration: remove width and add display: inline-block;:
.header {
/* width: 200px; don't set width anymore */
background-color: #c2ccd1;
padding: 4px;
margin: 2px;
display: inline-block; /* force displaying DIV as an inline element */
}
To control space between text and arrow just use margin-left property for .header:after part:
.header:after {
content: "";
float: right;
margin-top: 7px;
visibility: hidden;
margin-left:4px; /* space between text and arrow for inline elements */
}
OR if you want to preserve a space for the arrow in the inline elements (to avoid width changes on hover) - you can also add transparent 'arrow'
.header:after {
content: "";
float: right;
margin-top: 7px;
visibility: visible; /* make it visible by default */
margin-left:4px; /* space between text and arrow for inline elements */
border: 4px solid transparent; /* set borders to transparent, so they won't show */
}
I'm trying to override a CSS class which is used to display an arrow. I want to make the arrow disappear. This class is found in the Liferay theme.
this CSS class:
.v-tabsheet-tabitem-selected:after {
border: 10px solid;
border-bottom-width: 0;
border-color: #333 transparent transparent;
bottom: -6px;
content: '-';
display: block;
height: 0;
left: 50%;
margin-left: -10px;
position: absolute;
text-indent: -9999px;
width: 0;
}
I did:
.v-tabsheet-tabitem-selected:after{
content: none;
}
It does not seem to work, is there any other way?
It looks like the arrow is being drawn with CSS borders, so try overriding it with this:
.v-tabsheet-tabitem-selected:after {border: none;}
For the CSS you have provided, your cursor position should not be relevant. That means you either have a :hover selector applying elsewhere or JavaScript that applies based on mouse events.
See this code example: http://jsfiddle.net/Z2BMK/
Chrome/IE8 look like this
Firefox looks like this
My CSS is
button {
padding:0;
background:#080;
color:white;
border:solid 2px;
border-color: #0c0 #030 #030 #0c0;
margin:0;
}
How can I change the code sample to make the button the same in both browsers? I do not want to use JavaScript based hyperlinks because they do not work with space bar on keyboard and it has to have an href URL which is not a clean way to handle things.
My solution, since Firefox 13
button::-moz-focus-inner { margin: -1px; padding: 0; border-width: 1px; }
Add this:
button::-moz-focus-inner {
padding: 0;
border: 0
}
http://jsfiddle.net/thirtydot/Z2BMK/1/
Including the border rule above is necessary for buttons to look the same in both browsers, but also it removes the dotted outline when the button is active in Firefox. Lots of developers get rid of this dotted outline, optionally replacing it with something more visually friendly.
To fix it on input elements as well add
input[type="reset"]::-moz-focus-inner,
input[type="button"]::-moz-focus-inner,
input[type="submit"]::-moz-focus-inner,
input[type="file"] > input[type="button"]::-moz-focus-inner
is simple perfect!
Corrected version of #thirtydot's answer:
button:: {
padding: 0px;
border: 0px;
}
button::-moz-focus-inner {
padding: 0px;
border: 0px;
}
Regarding Firefox 87:
button in button::-moz-focus-inner cannot be a class. (E.g. .mybutton::-moz-focus-inner does not work)
There must be a button { padding:0px; border: 0px; } style present as well (This style can be given per class).
