Have come against an interesting problem and I'm stumped.
Basically on one of our pages we have a couple of hyperlinked areas. These areas are not only clickable where they have text but throughout the entire background by setting the link with display:block. You can see a simple example of such a clickable area here.
So recently the powers that be have asked me to add another link within this area. The inner link would have a different target to clickable area and will only be clickable for it's immediate text and the rest of the clickable area will wrap around it. You can see how this would fit together in this demo (the yellow bit represents the clickable portion of the inner link and the red represents the outer link).
NOTE: I realise this looks a very messy implementation but I'm afraid it's out of my hands.
By design (and for good reason) I cannot simply nest my <a> tags like so:
<a href="#" class="clickable_area">
<span>RED Background and clickable</span><br/>
<span>RED Background and clickable</span><br/>
<span>RED Background and clickable</span><br/>
<a class="inner_link" href="#">Yellow background and it's own link</a><br/>
</a>
Trying to nest the tags like this causes the outer link to be closed prematurely by the first instance of </a> as seen here.
One solution may be to make the inner link a span element and then use onclick events to perform the hyperlink via JavaScript but I'm not too found of this approach and would really prefer to avoid any JavaScript workarounds.
I've tried a couple of workarounds with CSS etc. but as yet I've come up dry. I've a feeling that absolute positioning or negative margining could be key but I've never been any good at either.
If anyone could offer up any suggestions I'd be very appreciative.
You can't nest links. My suggestion is to absolutely position the inner link over top of the outer area, somewhat like this:
<div class="container" style="position:relative">
<a href="...">
<span>RED Background and clickable</span><br/>
<span>RED Background and clickable</span><br/>
<span>RED Background and clickable</span><br/>
</a>
link 2
</div>
You can't nest links, but use absolute positioning.
<div id="wrapper">
<a id="bigred" href="...">Big clickable area</a>
<a id="yellow" href="...">Yellow background link</a>
</div>
CSS
#wrapper {
position: relative;
height: 300px;
width: 500px;
}
#bigred {
background: #ff0000;
position: absolute;
top: 0;
left: 0;
height: 300px;
width: 500px;
}
#yellow {
background: #ffff00
position: absolute;
top: 30px;
left: 30px;
}
Both links will be clickable. Yellow is drawn on top of red because of source order. If you change the order you will need to use z-index to control which displays on top of which.
Here you go a working example:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<body>
<style>
a {text-decoration:none; background-color:red}
.clickable_area{display:block;color:#000; padding-bottom: 20px;}
.container{position: relative;}
.inner_link{position:absolute; bottom: 0px; background-color:yellow}
</style>
<div class="container">
<a href="#" class="clickable_area">
<span>RED Background and clickable</span><br/>
<span>RED Background and clickable</span><br/>
<span>RED Background and clickable</span><br/>
</a>
<a class="inner_link" href="#">Yellow background and it's own link</a>
</div>
</body>
</html>
I'd use a div to wrap your links. Is this what you're going for? http://jsfiddle.net/wcCMC/3/

I'm having trouble getting the right selector.
Let me try to explain the best way I can:
I'm working on a project that I cannot change HTML and Javascript, it has some dynamic HTML and other reasons.
On the project, there is an image on a <img> tag.
However, I need to change colors between two layouts, and as you can see on the HTML/CSS the only way I got that to work is to hide th <img> tag and set a background to the anchor, that has a title.
So, now, when I change the layouts, the image changes, however there is also something else, this image on click hides the menu and changes the image one more time.
Now, I need to hide the background on the anchor when the title on the image changes.
Here is the HTML BEFORE clicking the image
<div id="div-mh-ico">
<ul id="ul-icone-mh" class="icones">
<li>
<a href="#" class="mh-icon" title="Esconder menu horizontal" onclick="hideMenuHorizontal();">
<img title="Esconder menu horizontal" id="imgHideMenu" src="images/ico_hidemh.png" width="16" height="16">
</a>
</li>
</ul>
And here is the HTML AFTER I click on the image
<div id="div-mh-ico">
<ul id="ul-icone-mh" class="icones">
<li>
<a href="#" class="mh-icon" title="Esconder menu horizontal" onclick="hideMenuHorizontal();">
<img title="Exibir menu horizontal" id="imgHideMenu" src="images/ico_showmh.png" width="16" height="16">
</a>
</li>
</ul>
THE CSS
I HIDE THE ORIGINAL IMAGE, USED ON THE OTHER LAYOUT
#ul-icone-mh li a img {
visibility: hidden !important;
}
AND SET THE NEW IMAGE
a[title="Esconder menu horizontal"] {
box-sizing: border-box;
background-image: url(../images/ico_hidemhc.png);
background-size: 16px;
background-repeat: no-repeat;
}
And when I click it, the image stays the same, but I need to hide that image when the title changes and add another image.
Any ideas what I can do?
You need a bit more than just the right CSS selector. The problem there is the old stumbling block that there is no parent selector.
A bit more thought and work is required.
img { height:50px; width:50px }
ul {padding: 0; list-style:none;}
.icones a::after {
content: '';
height:50px; width:100px;
background-image: linear-gradient(to right, #00FF00 50%, #0000FF 50%);
display:inline-block;
}
.icones a {
height:50px; width:50px;
display:block;
white-space:nowrap;
overflow:hidden;
font-size:0;
}
.icones a img[title='Esconder menu horizontal'] {
margin-left: -50px;
}
.icones a img[title='Exibir menu horizontal'] {
margin-left: -100px;
}
<div id="div-mh-ico">
<ul id="ul-icone-mh" class="icones">
<li>
<a href="#" class="mh-icon" title="Esconder menu horizontal" onclick="hideMenuHorizontal();">
<img title="Esconder menu horizontal" id="imgHideMenu" src="http://placehold.it/200/ff0000" width="16" height="16">
</a>
</li>
</ul>
</div>
<div id="div-mh-ico">
<ul id="ul-icone-mh" class="icones">
<li>
<a href="#" class="mh-icon" title="Esconder menu horizontal" onclick="hideMenuHorizontal();">
<img title="Exibir menu horizontal" id="imgHideMenu" src="http://placehold.it/200/990000" width="16" height="16">
</a>
</li>
</ul>
</div>
Here I've increased the images to 50x50px from 16x16px to make them a bit easier to see but the principle is just the same.
For the two images referenced by the HTML, I've used two blocks that are different shades of red.
For the two CSS overlay images, for simplicity I've used a linear gradient making a block that's the height of the image and twice the width. The left half is green and the right half blue. You would use a sprite for the two images you want to display. The left half of the sprite would contain the "Esconder ..." replacement image and the right half of the sprite would contain the "Exibir ..." replacement image.
I've also shown both cases together rather than switching between them on click, again for simplicity.
The idea is that the left margin of the image is made negative to shift it out of the a element. The pseudo element that follows contains the sprite and is shifted into that space, either by the width of the image, or twice the width of the image to show different contents for the two cases.
Hence we get a green box for the "Esconder ..." case and a blue box for the "Exibir ..." case.
So if I understand correctly, then the title is "esconder", you want to hide the default image and inject your own. And otherwise you want to show the original (when the title is "exibir".)
You have correctly identified how you would target the a tag based on the title: a[title="Esconder menu horizontal"]. What you then need to do is only exclude the image when it is inside of this tag, and then replace it with your own image. You then also need to give it an explicit size, and declare the a tag which now directly has the background image with some size. Like so:
a[title="Esconder menu horizontal"] img { display: none; }
a[title="Esconder menu horizontal"] {
box-sizing: border-box;
background-image: url(../images/ico_hidemhc.png);
background-size: 16px;
background-repeat: no-repeat;
height: 16px;
width: 16px;
display:inline-block;
}
You will notice I added a few lines to your existing styling:
display:inline-block tells the browser that this element should follow the flow like an inline element, but should have block-type semantics. By default, an anchor tag is an inline element, which means it doesn't have explicit size or width -- just what is enforced by its children. Since you've delcared that the child is not to be seen, the anchor tag effectively collapses to be of 0x0 size.
height:16px; width:16px tells the browser the size you want for this image. I guessed at these dimensions based on the background-size property you had set. Since we've told the browser using the display property that this element has explicit size, we now tell it what that size is.
It's not very clear what you're trying to accomplish, but if you're trying to change the anchor based on the image, this is simply not possible using CSS alone.
You can target child elements based on their parents, but you can not target parent elements based on their children in CSS (currently).
The only way to do this would be to affect how the HTML renders the two options, or using Javascript.
There are a few different suggested specs for such a selector, but none have yet been implemented.
Since the img tag is what has the dynamic title, that is the only thing you will be able to target with your CSS. If you cannot accomplish your task by targeting the img then it can't be done within the constraints you stated.

Here is what I am trying to accomplish in HTML/CSS:
I have images in different heights and widths, but they are all under 180x235. So what I want to do is create a div with border and vertical-align: middle them all. I have successfully done that but now I am stuck on how to properly a href link the entire div.
Here is my code:
<div id="parentdivimage" style="position:relative;width:184px;height:235px;border-width:2px;border-color:black;border-style:solid;text-align:center;">
<div id="childdivimage" style="position:absolute;top:50%;height:62px;margin-top:-31px;">
<img src="myimage.jpg" height="62" width="180">
</div>
</div>
Please note that for the sake of copy pasting here easily, the style code is inline.
I read somewhere that I can simply add another parent div on top of the code and then do a href inside that. However, based on some research it won't be valid code.
So to sum it up again, I need the entire div (#parentdivimage) to be a href link.
UPDATE 06/10/2014: using div's inside a's is semantically correct in HTML5.
You'll need to choose between the following scenarios:
<a href="http://google.com">
<div>
Hello world
</div>
</a>
which is semantically incorrect, but it will work.
<div style="cursor: pointer;" onclick="window.location='http://google.com';">
Hello world
</div>
which is semantically correct but it involves using JS.
<a href="http://google.com">
<span style="display: block;">
Hello world
</span>
</a>
which is semantically correct and works as expected but is not a div any more.
Why don't you strip out the <div> element and replace it with an <a> instead? Just because the anchor tag isn't a div doesn't mean you can't style it with display:block, a height, width, background, border, etc. You can make it look like a div but still act like a link. Then you're not relying on invalid code or JavaScript that may not be enabled for some users.
Do it like this:
Parentdivimage should have specified width and height, and its position should be:
position: relative;
Just inside the parentdivimage, next to other divs that parent contains you should put:
<span class="clickable"></span>
Then in css file:
.clickable {
height: 100%;
width: 100%;
left: 0;
top: 0;
position: absolute;
z-index: 1;
}
The span tag will fill out its parent block which is parentdiv, because of height and width set to 100%. Span will be on the top of all of surrounding elements because of setting z-index higher than other elements. Finally span will be clickable, because it's inside of an 'a' tag.
Going off of what Surreal Dreams said, it's probably best to style the anchor tag in my experience, but it really does depend on what you are doing. Here's an example:
Html:
<div class="parent-div">
Test
Test
Test
</div>
Then the CSS:
.parent-div {
width: 200px;
}
a {
display:block;
background-color: #ccc;
color: #000;
text-decoration:none;
padding:10px;
margin-bottom:1px;
}
a:hover {
background-color: #ddd;
}
http://jsbin.com/zijijuduqo/1/edit?html,css,output
Two things you can do:
Change #childdivimage to a span element, and change #parentdivimage to an anchor tag. This may require you to add some more styling to get things looking perfect. This is preffered, since it uses semantic markup, and does not rely on javascript.
Use Javascript to bind a click event to #parentdivimage. You must redirect the browser window by modifying window.location inside this event. This is TheEasyWayTM, but will not degrade gracefully.
I'm surprised no one suggested this simple trick so far! (denu does something similar though.)
If you want a link to cover an entire div, an idea would be to create an empty <a> tag as the first child:
<div class="covered-div">
<a class="cover-link" href="/my-link"></a>
<!-- other content as usual -->
</div>
div.covered-div {
position: relative;
}
a.cover-link {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
}
This works especially great when using <ul> to create block sections or slideshows and you want the whole slide to be a link (instead of simply the text on the slide). In the case of an <li> it's not valid to wrap it with an <a> so you'd have to put the cover link inside the item and use CSS to expand it over the entire <li> block.
Do note that having it as the first child means it will make other links or buttons inside the text unreachable by clicks. If you want them to be clickable, then you'd have to make it the last child instead.
In the case of the original question:
<div id="parentdivimage" style="position:relative;width:184px;height:235px;border-width:2px;border-color:black;border-style:solid;text-align:center;">
<a class="cover-link" href="/my-link"></a> <!-- Insert this empty link here and use CSS to expand it over the entire div -->
<div id="childdivimage" style="position:absolute;top:50%;height:62px;margin-top:-31px;">
<img src="myimage.jpg" height="62" width="180">
</div>
<!-- OR: it can also be here if the childdivimage divs should have their own clickable links -->
</div>
Make the div of id="childdivimag" a span instead, and wrap that in an a element. As the span and img are in-line elements by default this remains valid, whereas a div is a block level element, and therefore invalid mark-up when contained within an a.
put display:block on the anchor element. and/or zoom:1;
but you should just really do this.
a#parentdivimage{position:relative; width:184px; height:235px;
border:2px solid #000; text-align:center;
background-image:url("myimage.jpg");
background-position: 50% 50%;
background-repeat:no-repeat; display:block;
text-indent:-9999px}
<a id="parentdivimage">whatever your alt attribute was</a>
This can be done in many ways.
a. Using nested inside a tag.
<a href="link1.html">
<div> Something in the div </div>
</a>
b. Using the Inline JavaScript Method
<div onclick="javascript:window.location.href='link1.html' ">
Some Text
</div>
c. Using jQuery inside tag
HTML:
<div class="demo" > Some text here </div>
jQuery:
$(".demo").click( function() {
window.location.href="link1.html";
});
I simply do
onClick="location.href='url or path here'"
What I would do is put a span inside the <a> tag, set the span to block, and add size to the span, or just apply the styling to the <a> tag. Definitely handle the positioning in the <a> tag style. Add an onclick event to the a where JavaScript will catch the event, then return false at the end of the JavaScript event to prevent default action of the href and bubbling of the click. This works in cases with or without JavaScript enabled, and any AJAX can be handled in the Javascript listener.
If you're using jQuery, you can use this as your listener and omit the onclick in the a tag.
$('#idofdiv').live("click", function(e) {
//add stuff here
e.preventDefault; //or use return false
});
this allows you to attach listeners to any changed elements as necessary.

Hi I have the following code to have few links on top of img. It works well in FF but not in IE. It seems IE is not clickable if you put link on top of img
<div style="z-index:-6755;"><img alt="October Offer" src="images/offers/october-offer.jpg" /></div>
<a href="#" onclick="window.parent.SqueezeBox.close();">
<div style="display:block; width: 185px; height: 32px; position: relative; bottom: 50px; left: 260px;border:1px solid blue; "> </div>
</a>
are you just trying to make the image clickable?
you can't have <href> that's not a correct html tag.
either place <img> inside <a> like so: <img />
another way is to set a div with a background image of your image and then a link inside there, make the link display : block and make it the entire width and height of the div and the whole thing will be clickable.
You can add an on-click function to img-tag.
Example:
<img src="images/logo.png" alt="logo" onclick="home()">
and then redirect it to a page.
function home(){ location.replace("/index.html") }
Implementing a "play video" function on a web site. Each video content item can have a different image. Each of these images will have the same width, but potentially differing heights (they are resized on upload to maintain aspect ratio to meet standard width requirements).
The plan was to display another transparent "play button" image over top of the content image using markup like this:
<div class="media">
<a class="videoLink" href="#" style="background-image: url(http://cloud.github.com/downloads/malsup/cycle/beach2.jpg);" >
<img src="PlayButton.png" alt="Click to Play" height="200" width="300" />
</a>
</div>
This is very similar to how channel 9 does it on their home page. This, however, appears to assume any image is of standard height and width. Are there alternative ways of tackling this?
Forgot to mention originally. We have a predefined width that things will fit into, however, each image may have a different height. For example, the same markup needs to be used to support the following images:
W x H
400 x 200
400 X 300
400 X 400
The Play button needs to be centered in each image.
Instead of the inner element being an <img>, you could make it a <div>, styled with the playbutton as the background image, positioned in the center.
<div class="media">
<a class="videoLink" href="#" style="background-image: url(http://cloud.github.com/downloads/malsup/cycle/beach2.jpg);" >
<div style='background:url(PlayButton.png) center center;' alt="Click to Play" height="200" width="300" />
</a>
</div>
You'll still need to know the size of the thumbnail image, as you'll still need to supply height and width for the div - since you're displaying the thumbnail as a background image, you won't be able to have the box scale to the right size automatically. But at least now your code can set the values for height and width without worrying about the shape of the play button getting distorted.
(note: the play button as a background image should probably be in a separate stylesheet rather than being declared inline as per my example; I did it like that to demonstrate how it differs from your original code, rather than to show best practice)
Need some your CSS to make sure things work, but this may help you:
.media {
display: table;
}
.media img {
display: table-cell;
vertical-align: middle;
display: block;
margin: 0 auto;
}
If not, please add you CSS so I can Fiddle it and make it happen.
I'd do it like this.
<div class="media">
<a class="videoLink" href="#"></a>
<img class="thumbnail" src="http://cloud.github.com/downloads/malsup/cycle/beach2.jpg"/>
</div>
Separate the thumbnail image from the link. We want the link to appear on top of the image, and the image to stretch the height of the <div class="media">.
The CSS:
.media {
position: relative;
}
.videoLink {
display: block;
height: 100%;
width: 100%;
background-image: url(PlayButton.png);
background-position: center center;
position: absolute;
z-index: 2;
}
I have 3 links that represent the content for one iFrame in my page. When you click each link, it'll reload the contents of that iFrame without reloading the page.
how do i set the image of my link to change when it's active?
here's my code:
<div id="tabs">
<div id="overview">
<a id="overviewtab" target="tabsa" href="toframe.html">Overviews</a>
</div>
<div id="gallery">
<a target="tabsa" href="tawagpinoygallery.html">Gallery</a>
</div>
<div id="reviews">
<a target="tabsa" href="trframe.html">Reviews</a>
</div>
</div>
<div id="tabs-1">
<!--<div id="scroller">-->
<iframe name= "tabsa" width="95%" height="100%" frameborder="0"></iframe>
</div>
CSS code:
#gallery a {
text-indent: -9999px;
padding-top: 40px;
background: url(../images/GalleryTab.png) no-repeat;
height: 51px; width: 123px; position: absolute; z-index: 2;
}
#gallery a:active, a:hover {
text-indent: -9999px;
padding-top: 40px;
background: url(../images/galleryoverview.png) no-repeat;
height: 51px;
width: 123px;
position: absolute;
z-index: 2;
}
it doesn't seem to work.. :o i only see the change in image when i hold the mouse down on the link, but when i click it, the image remains the same as if it wasn't the active tab. :o thanks!!
I am not seeing a style for visited? Only active and hover.
add
#gallery a:visited{}
style and see if that helps.
But I wonder if that is what you are actually asking? You may want to link to be displayed differently from the other links if its the last link that the user clicked. To do that you may have to use some javascript.
For example, if you use jQuery you can do something like this:
$("#gallery a").click(function(){
$("#gallery a").removeClass("ActiveClass");
$(this).addClass("ActiveClass");
});
where ActiveClass is a CSS class for styling the link appropriately.
EDIT based on comment below.
Let us assume that you have three links that look the same (call that lookA). You click on one and it looks different from the other two (lookB) but the other two still looks the same (lookA). You then click on a second link. The second link is not lookB and the other two links are lookA. Does this sound like what you want? At least that is how I interpret your question.
Hence, create two classes in CSS:
.lookA {/*Style for lookA*/}
.lookB {/*Style for lookB*/}
of course you can use more meaningful names.
Then you can add a class to each of the links that you need to use in this scenario like this:
<div id="tabs">
<div id="overview">
<a class="imagelink lookA" id="overviewtab" target="tabsa" href="toframe.html">Overviews</a>
</div>
<div id="gallery">
<a class="imagelink lookA" target="tabsa" href="tawagpinoygallery.html">Gallery</a>
</div>
<div id="reviews">
<a class="imagelink lookA" target="tabsa" href="trframe.html">Reviews</a>
</div>
</div>
So that each link can be refered to by its class, that is, imagelink. Also each link has a default lookA.
Now in jQuery (I know you did not specify jQuery but using it is 100 times simpler than plain Javascript).:
$(document).ready(function(){
$(".imagelink").click(function(){
$(".imagelink").removeClass("lookB");
$(this).addClass("lookB");
return true;
});
});
So on click on the link, it removes lookB from any other link and applies it only to the clicked link.
Hope this helps a bit.
I believe the selector is:
#gallery a:focus {...}
This is (inevitably) applied variably across browsers, however.
Stu Nicholls has a demo over on CSS Play, this demo being to remove the default outline of the focussed element, and otherwise style the clicked element.
Presumably this would be more reliably effected with jQuery, but it can be done with CSS.
