In this jsfiddle I'm trying to create a link that covers the entirety of the sprite image. For some reason though, the height and width attributes of a don't seem to work.
What can I do to create links from sprite images?
add display:inline-block or display:block to a for dimensions to work. dimensions don't take effect for inline elements.
I've updated your fiddle. The link covers the whole image now and this is done by turning the link into a block element with display: block like many other answers above state. I also added the id selector to all your other selectors and moved the selector and declaration with where the actual background image is being declared to the top. The reason for this, is that the li-element's background-position were overwritten because of lack of specificity and due to the order of your css declarations.
Use this
// Code shifted to the end.
Where, CSS is like this:
.sprite-sp1{
background-position: 0 0;
width: 242px;
height: 244px;
}
.sprite-sp1 a{
width: 242px;
height: 244px;
border: 1px solid;
}
.sprite-sp2{
background-position: 0 -294px;
width: 241px;
height: 244px;
}
#container li {
background: url(http://i.imgur.com/iDrt8.png) no-repeat top left;
}
EDIT Edited to make the sprite clickable. The new code shall be:
<ul id="container">
<li><span class="sprite-sp1"></span>test</li>
<li><span class="sprite-sp1"></span></li>
</ul>
Add display:block; to a, it will work then...

I have a problem with hover. I have a normal pic with opacity and another one with white background. I did this:
html:
<div id="glob" style="margin-right:5px;margin-top:2px;float:right;height:45px;width:40px;">
<img src="images/icon_globus.png" width="32" height="33" alt="" style="margin-right:5px;margin-top:7px;"/>
</div>
css:
#glob:hover{
background:url('../images/icon_globushover.png') no-repeat;
}
As you can see from the pic, the white one (upper globus) is behind the other one. It should not be behind.
What is not good?
EDIT: Thanks all, it's working. I did like the first answer. Don't know why I used img tag. I always use divs as image, but here I was stupid. Thanks a lot all for your help!
Because background always has the lowest z-index of all elements and content will be on top of it. I would suggest you to put "images/icon_globus.png" this as a background for div glob and remove that image tag. Then it should work the way you want it.
try without the image part.
glob {
background: url('icon_globus.png');
}
glob:hover {
background: url('icon_globus_hover.png');
}
Depending on the browsers you want to support, you could do something like this in CSS:
#glob { position: relative; }
#glob:hover:after {
content: '';
display: block;
position: absolute;
z-index: 1000;
left: 0;
top: 0;
right: 0;
bottom: 0;
background:url('../images/icon_globushover.png') no-repeat;
}
Because your image icon_globus.png is above your div background so when you hover, you actually apply a background to the container containing your image, you globushover appears behind your ..
try this instead:
html:
<div id="glob></div>
css:
#glob {margin-right:5px;margin-top:2px;float:right;height:45px;width:40px;background:url('../images/icon_globus.png') no-repeat;}
#glob:hover{
background:url('../images/icon_globushover.png') no-repeat;
}
this way you change/overwrite the default background-image. css means cascade style, cascade is wat permits you to overwrite styles depending on a certain condition, thats theory applied here. just overwrite a background-image with another one on hover.
remove all style and change as below
// CSS
glob:hover{background: url("/images/icon_globushover.png") no-repeat;}
.glob{
background: url("/images/icon_globus.png") no-repeat;
float: right;
margin: 0px 0px 15px 20px;
overflow: hidden;
padding: 0px;
width: 32px;
height: 33px;
}
<div class="glob"></div>
if your path source is like this
myhardrive/MysiteFolder/Images/ and your index.html is in MysiteFolder so in css must be (/images/)
if your path source is like this
myhardrive/MysiteFolder/files/mystyle.css here you do ("..\images\")
I have a html page which is using the same icon many times, and so I have embedded that icon as a background-image in css.
In css, the class for the icon is like this:
.user {
background-image: url(data:image/png;base64,...encoded png file...);
background-position: 0 0;
background-repeat: no-repeat;
width: 16px;
height: 16px;
}
I display the icon using a<span class='user'></span> tag, so far, so good.
I want the icon to be a link to another page, but I can't make the icon look correct when I do this.
I have tried:
<img class="user" src=""></img>
but this draws a broken link icon over it in Explorer, it looks ok, but has a border in Chrome. It is obviously wrong.
I also tried:
<span class="user"></span>
and this works, but the mouse cursor does not change to a pointer when over the icon.
What should I be doing?
You should make the element block level (at least inline-block) to set the width/height and explicitly set the cursor. These two things are the key components.
.user {
background-image: url(data:image/png;base64,...encoded png file...);
background-position: 0 0;
background-repeat: no-repeat;
display: inline-block; /* set display so you can set width/height */
cursor: pointer; /* ensure it shows the link cursor */
width: 16px;
height: 16px;
}
And the HTML:
<span class="user"></span>
So, you end up with an inline-block element which shows the image, and then you wrap that with an anchor. This is basically the same as wrapping an anchor around an <img />.
Alternatively, you could do this with just the <a>. You would use the exact same CSS, with this HTML:
Both should achieve what you're after. The difference between these two choices is mostly semantics.
You can set the class attribute on the anchor tag.
Are you looking for something like THIS
The HTML:
The CSS:
.user {
text-indent: -99999px;
background: url("http://www.google.co.in/images/srpr/logo4w.png") no-repeat top left;
float: left;
overflow: hidden;
width: 600px;
height: 200px;
margin: 10px;
}
Hope this is what you need.
try to add this one on your css
cursor:pointer;/*Link with poniter*/
<span class="user" /></span>
If I have an image like this (for example):
(source: tiscali.it)
with more background element for my web site, how can extract a single element with css properties?
You should use the "CSS Sprite" method. It means that you need to create an element block width specified width and height, then give it a background-image along with background-position and backgorund-url, then hide everything that goes out of the box overflow:hidden;
reference to this tutorial for example, it's well explained there: CSS Sprite link
Use CSS sprites
http://www.google.de/search?q=css+sprites
Example with your image
http://jsfiddle.net/qxVf8/
html
<div class="sprite sprite1">
</div>
css
.sprite {
background: url(http://www.tiscali.it/v007/img/el.v004.png) 0 0 transparent;
}
.sprite1 {
width: 79px;
height: 28px;
background-position: -0px -305px;
border: 1px solid magenta;
}
You can use the css sprites technique for that.
I want to show images on the page but I don't want to hardcode the references to the images in html.
Is it possible to do something like:
HTML:
<span id="got-easier"></span>
CSS:
#got-easier { image: url(/i/trend-down.gif); }
(IE6 should be supported)
Yes, use a background image :)
#got-easier { background-image: url(/i/trend-down.gif); }
Remember to set a span to display: block; and set width/height of your image if you use it.
As David Dorward pointed out, if it's an image relevant to the information, it should be included in the document with an <img> tag and alt attribute.
Heya, the common term for it is css Image Replacement technique (or IR). Here are the commonly used methods currently. Just choose any of the two ;)
/* Leahy Langridge Method */
span#imageName {
display: block;
height: 0 !important;
overflow: hidden;
padding-top: 0px; /* height of image */
width: 0px; /* width of image */
background: url(url/of/image.jpg) no-repeat
}
/* Phark Method */
span#imageName {
display: block;
width: 0px;
height: 0px;
background: url(url/of/image.jpg) no-repeat;
text-indent: -9999px
}
In case you want to display the images inline, position:absolute does the trick:
#got-easier {
display:inline;
position:absolute;
width:img-Xpx;
height:img-Ypx;
background:url(/i/trend-down.gif) no-repeat;
}
The only problem with this is that, since the image position is absolute, it will overlay whatever is next to it (in IE6 it might appear behind), and the workarounds that I found to fix this (with both CSS and jQuery) aren't supported in IE6. Your image-container will have to be followed by new line.
This might be useful when, for instance, you'd like to place a (?) image next to a form caption or a button (that usually have nothing next to them) to display help with onmouseover.
I know this is probably the dumbest question ever, however I am a total beginner when it comes to CSS; how do you hyperlink an image on a webpage using an image which is sourced from CSS? I am trying to set the title image on my website linkable to the frontpage. Thanks!
Edit: Just to make it clear, I'm sourcing my image from CSS, the CSS code for the header div is as follows:-
#header
{
width: 1000px;
margin: 0px auto;
padding: 0px 15px 0px 15px;
border: none;
background: url(images/title.png) no-repeat bottom;
width: 1000px;
height: 100px;
}
I want to know how to make this div hyperlinked on my webpage without having to make it an anchor rather than a div.
You control design and styles with CSS, not the behavior of your content.
You're going to have to use something like <a id="header" href="[your link]">Logo</a> and then have a CSS block such as:
a#header {
background-image: url(...);
display: block;
width: ..;
height: ...;
}
You cannot nest a div inside <a> and still have 'valid' code. <a> is an inline element that cannot legally contain a block element. The only non-Javascript way to make a link is with the <a> element.
You can nest your <a> tag inside <div> and then put your image inside :)
If you don't want that, you're going to have to use JavaScript to make your <div> clickable:
Document.getElementById("header").onclick = function() {
window.location='...';
}
To link a css-sourced background-image:
#header {
display:block;
margin: 0px auto;
padding: 0px 15px 0px 15px;
border: none;
background: url(images/title.png) no-repeat bottom;
width: 1000px;
height: 100px;
}
<a id="header" href="blah.html" class="linkedImage">
The key thing here is to turn the anchor tag into a block element, so height and width work. Otherwise it's an inline element and will ignore height.
That's really not a CSS thing. You still need your A tag to make that work. (But use CSS to make sure the image border is either removed, or designed to your required spec.)
<img src="foo" class="whatever" alt="foo alt" />
EDIT: Taking original intent (updated question) into account, a new code sample is below:
<img id="header" alt="foo alt" />
You're still in an HTML world for links, as described by other answers on this question.
sorry to spoil your fun ladies and gentlemen, it is possible.
Write in your header: [link](http://"link here")
then in your css:
#header a[href="https://link here"] {
display: inline-block;
width: 75px;
height: 75px;
font-size: 0;
}
.side .md a[href="link here"] {
background: url(%%picture here%%) no-repeat;
}
then in your css
.titleLink {
background-image: url(imageUrl);
}
You still create links in HTML with 'a' (anchor) tags just like normal. CSS does not have anything that can specify if something is a link to somewhere or not.
Edit
The comments of mine and others still apply. To clarify, you can use JavaScript to make a div act as a link:
<div id="header" onclick="window.location='http://google.com';">My Header</div>
That isn't really great for usability however as people without JavaScript enabled will be unable to click that and have it act as a link.
Also, you may want to add a cursor: pointer; line to your CSS to give the header div the correct mouse cursor for a link.
CSS is for presentation only, not content. A link is content and should be put into the HTML of the site using a standard <a href=""> tag. You can then style this link (or add an image to the link) using CSS.
You have to use an anchor element, wrapped in a container. On your homepage, your title would normally be an h1, but then on content pages it would probably change to a div. You should also always have text in the anchor element for people without CSS support and/or screen readers. The easiest way to hide that is through CSS. Here are both examples:
<h1 id="title"><a title="Home" href="index.html>My Title</a></h1>
<div id="title"><a title="Home" href="index.html>My Title</a></div>
and the CSS:
#title {
position:relative; /*Makes this a containing element*/
}
#title a {
background: transparent url(../images/logo.png) no-repeat scroll 0 0;
display:block;
text-indent:-9999px; /*Hides the anchor text*/
height:50px; /*Set height and width to the exact size of your image*/
width:200px;
}
Depending on the rest of your stylesheet you may need to adjus it for the h1 to make it look the same as the div, check out CSS Resets for possible solutions to this.
Try this - use an H1 as the seat of your graphic instead. Saved my butt time and time again:
<h1 class="technique-six">
CSS-Tricks
</h1>
h1.technique-six {
width: 350px;
padding: 75px 0 0 0;
height: 0;
background: url("images/header-image.jpg") no-repeat;
overflow: hidden;
}
Accessible, and also solid across browsers IE6 and > . You could also link the H1.
HTML is the only way to create links - it defines the structure and content of a web site.
CSS stands for Cascading Style Sheets - it only affects how things look.
Although normally an <a/>; tag is the only way to create a link, you can make a <div/> clickable with JavaScript. I'd use jQuery:
$("div#header").click(function() {window.location=XXXXXX;});
