Hyperlinking an image using CSS - html

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;});

My div ID is not styling - what am I doing wrong?

Question 1: css doesn't style div id
In my html file I've created a div id for a top bar (with text + social links). In the related css file I've created the corresponding style
#topbar {
height: 40px;
width: 100%;
background-color: #383433;
margin: auto;
overflow: hidden;
}
#topbar p {
color: white;
}
<div id="topbar">
<p>Text text text</p>
</div>
The text becomes white, but the height, background color etc. isn't coming through. Am I overlooking something?
Question 2: can I style an image as part of a div id?
Html:
<div id="scroller">
<img src="images/scroller-1.jpg">
</div>
When I add:
#scroller {
max-width: 100%;
height: auto;
}
The image doesn't get responsive / resized.
If I add:
#scroller img {
max-width: 100%;
height: auto;
}
It works.
So elements part of a div-id don't inherit the parent-style?
First of all: If you have two questions, its better to post them seperated. It is cleaner this way.
To question 1: It is working actually. You can run your pasted code snippet. Likely, some other style is overwriting it. Since we cant know which one it is, the only advice i can give you is to write !important behind your css code like this:
height: 40px !important;
This way, nothing can overwrite it except styles that also have an !important tag.
To question 2:
So elements part of a div-id don't inherit the parent-style?
Well, it depends. You can set the font-color of a div then the headlines and p tags in this div will have the same color unless you specify it otherwise like
#scroller{
color:blue;
}
#scroller p{
color:red;
}
Images dont inherit from divs. They are by default always the full image size so you have to specifiy their size seperately if it should be the full width at all times.
If it was helpful to you, pls mark the answer as accepted :)

Inline CSS - background position not working

I'm trying to use inline CSS to style an image sprite. So obviously, I need background-position to work, but it's not. I'm not sure what's wrong. It's supposed to be a clickable image that links to another page of the site, but the CSS isn't working.
<div class="homepage"><img src="http://imageLinkToHomepage.com/" style=background-image: "-20px;"></div>;
<div class="homepage"><img src="http://imageLinkToHomepage.com/" style="background-image:-20px;"></div>
I think you had some quote marks mixed up there...
Looks like you're trying to apply the background-position property to an image tag, which won't work. Background properties won't apply to image tags. For your specific use case, you could apply a background image to your anchor tag without needing an image element - like so:
<div class="homepage">
</div>
.image-button {
display: inline-block;
width: 55px;
height: 55px;
background: url('http://3.bp.blogspot.com/-q0CJBWRLWUs/T_z2_c7TunI/AAAAAAAABPk/rS7fmE1P-B4/s1600/megaman7.png') no-repeat 0px 0px;
}
.image-button:hover {
background-position: -55px 0px;
}

I was facing the same issue and I got it done by writing !important.No rule was overridden but css was not applying the position without making it important, seems like a bug.
<div class="ProposalBanner" style="background:url(...\imgs\BannerPRop.jpg) no-repeat center -31px !important"></div>

Why is <hr> given a thickness in HTML different than CSS?

I have a HTML document with inline CSS that my professor asked to have the CSS within the head tag and have the same rending from the original HTML with inline CSS. I think I'm done but somehow the <hr> within the HTML with inline CSS looks thicker than the other one.
I already tried adding a height: declaration property but it renders even thicker than I want.
Original HTML: http://jsfiddle.net/2k66T/
Modified HTML: http://jsfiddle.net/dd63m/
Edit: Here are the instructions from the professor;
Write a CSS document in order to define the style of the following web
page (I refer this to as "Original HTML") in a right way. Add and erase in the original
page everything you think that is necessary. Use the on-line validator
of the World Wide Web Consortium to be sure that your work fulfills
the standards.
Real question is... why are you using HR?
Let's render a border on the div wrapping your logo image.
Have a fiddle! - http://jsfiddle.net/dd63m/11/
Updated fiddle - http://jsfiddle.net/8VTd8/3/
I have given the div wrapping your logo an ID of logo. I removed the br break tags, we can apply margins in the CSS. The font tag is no longer used.
HTML
<h1>MyTSC</h1>
<div id="logo">
<img src="./img/TSCLogo.jpg" alt="TSC">
</div>
<h2>My courses for Fal 2013</h2>
<ul>
<li>COSC 4330 Computer Graphics</li>
<li>IMED 1416 Wed Design I</li>
<li>ITNW 2413 Networking Hardware</li>
</ul>
The logo div is currently 300px wide, change to what you want. Note: margin: 0 auto; essentially this is centering your div. margin-bottom is applied to create those extra spaces. The border is applied to your logo div giving a consistent line across browsers.
CSS
body{
background-color: grey;
color: white;
}
h1{
text-align: right;
margin-bottom: 30px;
}
div{
text-align: center
}
ul{
font-style: italic;
}
#logo { width: 300px; margin: 0 auto; border-bottom: solid 1px #FFF; }
#logo img { margin-bottom: 30px;}
add background: white; in your css not color:white
like this
hr{
width: 50%;
height: 3px;
background: white;
}
They all have the same height, the one with the default color(no color specified) has a gradient effect so it looks a little thin.
Code for the Test fiddle
<hr width="50%" color="black">
<br />
<br />
<hr>
<br />
<br />
<hr id="test">

How to show an image on html page using only css?

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.

Inserting another image next to <img> with :before

I'm trying to replace <img> elements with emoticons with different images through CSS (so that I can match them to the style being used). I thought that I can just insert another smiley with the :before CSS pseudo-element, and hide the original element. This would work, except that the browsers don't seem to insert the extra image! This only happens if I try it with an <img> element, works perfectly when I try it with <span>. The code I tried:
<!doctype html>
<style>
img.icon:before {
display: inline-block;
content: url(smiley.png);
width: 16px;
height: 16px;
}
</style>
<p>Lorem ipsum <img src="smiley.png" class="icon" alt=":)"> dolor sit amet...</p>
The specification at http://www.w3.org/TR/CSS2/generate.html#before-after-content has a note at the bottom:
Note. This specification does not
fully define the interaction of
:before and :after with replaced
elements (such as IMG in HTML). This
will be defined in more detail in a
future specification.
We are using a background image, like it is suggested in the comments, but that has the problem that the images won't print with default printing settings then. The next option we are considering is using <span class="icon"><img ...></span> and putting the :before on the span, but it's a little ugly.
I also wonder if this is specified in CSS3 so that there is a chance for fixing it in the near future.
It's almost certainly easier to use:
img.icon:before {
display: inline-block;
background-image: transparent url(smiley.png) 0 0 no-repeat;
width: 16px;
height: 16px;
}
You might not want to use background-image, but the :before and :after psuedo-elements are already poorly implemented; trying to use content to place images is probably a step too far at this stage.
I'm not sure I see the point of this approach, though; it seems you'll end with two versions of smiley.png next to each other. This might be more easily implemented (replacing the generic smiley.png with a themed smiley.png) on the server-side, than client.
Another way to do this is just set a background-image and hide the img element with overflow, without using :before:
<style>
.icon {
width: 0;
height: 0;
padding-top: 16px;
padding-left: 16px;
overflow: hidden;
background-position: 0 0;
background-repeat: no-repeat;
}
.smiley { background-image: url(smiley.png); }
</style>
<img class="icon smiley" src="smiley.png" alt=":)">
Also, have a look at this article about using data attributes instead of classes for this.
