Linking CSS embeded image - css

For a webpage I used a div id that with css inserts a logo directly in the page. I'd like that logo to be linked to (for instance) a homepage. I can make it easily by doing this
<a href=xyz><div id=logo></div></a>
of.course that doesn't validate (eventually DTD XHTML 1.0 Strict).
Can anyone suggest the (probably obvious) best practice?
Thanks

You can do away with fiddly SPAN and DIV cluttering up your page and have the link itself be a block.
And in your CSS, style it with background and size it to the dimensions of the image you want to be clickable:
#logo
{
background:url("/path/to/image.jpg");
display:block;
width:200px;
height:80px;
}

<span></span>
Apply the background image, width, height and display:block to the span. Hope that helps!

<span class="logo"></span>
You might have to declare <span> as display: block;.

Use a span:
<a href=xyz><span id=logo></span></a>
Don't forget to convert the span to a block element in your css:
.logo {
display: block
}

Why is css text-align:center, not centering text? Underlining in the same format is working

I wrote simple CSS to align text using the w3schools example with:
text-align:center
When I add an underline in the same format, the underline works.
Here's the snippet:
.CenterIt {
text-align:center;
}
.UnderlineIt {
text-decoration:underline;
}
<span class="UnderlineIt">
<span class="CenterIt">Registration Form</span>
</span>
Here's the w3schools page (the align text section):
https://www.w3schools.com/css/css_align.asp
In my full code I have the text I want to center inside another box. I've tried it both inside that box and outside any boxes. It doesn't center.
.CenterIt {
text-align:center;
display:block;
}
.UnderlineIt {
text-decoration:underline;
}
<span class="UnderlineIt">
<span class="CenterIt">Registration Form</span>
</span>
The display property of span by default is inline. i.e.,
display:inline;
Therefore, <span> will take only the width of its content. In contrast, block elements like <div>, by default, take the full line (and thereby the full width of the page) for its content.
To make the text-align work for <span>, you need to change it into a block element.
Set
display: block;
for the span with .CenterIt class. This will make .CenterIt take the full line (and thereby the full width of the page), and then the text-align: center; will centralize the content.
Try this. You need to wrap it with a container unit of <div>
<div class="UnderlineIt">
<div class="CenterIt">Registration Form</div>
</div>
Following will work as well
<span class="UnderlineIt">
<div class="CenterIt">Registration Form</div>
</span>
It might work better if you run “display: flex;” on the container span and “justify-content: center;” on the child span. Flexbox is a little easier to use when placing items within a container.
Because your html, is in wrong format. You cant have a span child of a span.
try like this:
<div class="CenterIt">
<span class="UnderlineIt">Registration Form</span>
</div>
to have the span centered , without a parent div you would need to put the display, as block.
so you could have on your html and css like this:
span{display:block;}
.CenterIt {
text-align:center;
}
.UnderlineIt {
text-decoration:underline;
}
html:
<span class="UnderlineIt CenterIt">Registration Form</span>

wrapping block elements with <a>

as i read around the web, it's a valid html5 practice to wrap block elements inside <a> elements. i have a problem though.
my html
<a href="http://google.com" target="_blank">
<div> </div>
</a>
my css
div {
background:#f00;
height:100px;
margin-left:10px;
width:300px;
}
a {background:blue;}
the link actually works, but i see no blue background and chrome says that my a have no height and width
changing the css of the a to display:inline-block does the trick here, but not in my website.
do you have any suggestion or solution? how come the a element doesn't "follow" its child?
thank you!
http://jsfiddle.net/72cYy/82/
it depends on what you're looking for, you can set a to display:block if you want it to behave like a block element:
a {
display: block;
background:blue
}
EXAMPLE 1
or you could set it to display: inline-block to make it behave like it natrually would:
a {
display: inline-block;
background:blue
}
EXAMPLE 2
There is no reason that either of these wouldn't work on your site. Perhaps you have CSS or javascript overwriting it? Both of these methods will fix the collapsed height/width issue. If it is a conflicting CSS issue you could be more specific by adding an id or a class:
a#wrapper{
display: inline-block;
}
or
a.wrapper{
display: inline-block;
}

Align icons and images to right, textarea to left (twitter-Bootstrap)

TL;DR : Before you read anything, the desired end-result is illustrated in the image below, otherwise refer to the JSFiddle. Preferably, I would like to only use CSS and not modify the DOM structure.
The icons must be aligned completely to the right (hence the .pull-right), but the icons must be stacked vertically (Sometimes some icons must not appear, so they are .hidden, like the .fa-undo icon in the second row).
(When I say 'the icons' i mean the <i> tags and the <img> tag)
The icons must not make the textarea go down (no margin on top of the textarea).
Hopefully, the WIDTH of the textarea would be dynamic and not statically put to width: 90%; for example. It should take as much width as possible, without interfering with the vertical icon stack.
Here is the end result that I want (in a perfect world this would be done using CSS and the same HTML DOM I provided)
In general, images that are UI elements, and not content, should be CSS backgrounds, not inline images. You then use class names to control the image content.
You should be doing this, or something similar:
td.fr {
background-image:url(/images/fr.gif);
background-repeat:no-repeat;
background-position: top right;
}
The same should go for your buttons. Use <button> and style the background.
Not exactly what you wanted I'm afraid, but this is how I'd achieve that result:
fiddle
<div class="pull-right icons">
<img src="http://www.convertnsftopst.net/images/gb.gif" class="pull-right" />
<i class="fa fa-reply"></i>
</div>
td .icons{
width:20px;
text-align:center;
}
Here is the end result that I want (in a perfect world this would be done using CSS and the same HTML DOM I provided)
I was unable to do it without adding another pull-right container, I fear that doing it with only CSS would end up being an odd hack
Fixed here : http://jsfiddle.net/QTXxp/2/
What was lacking when I asked this question was the clear:right; and the use of <div> (or display: block;)
Here is the CSS (if you're too lazy to open the JSFiddle) with the addition of the boostrap class pull-right on the div.icons
textarea.hover-edit {
width: 90% !important;
}
div.icons {
width: 10% !important;
}
div.icons > div > i.fa {
margin-top: 4px;
margin-right: 4px;
}
div.icons > div.action-icon-right {
float:right;
clear:right;
}

W3C validation of css sprite back button?

How can I make my css sprite back button validate through W3C? Here is my code to call the button.
<div class="icon-backbtn"></div>
I ended up using the below code to pass W3C validation and still using CSS Sprites.
<a id="icon-backbtn" title="Back" href="#" onclick="history.go(-1)"></a>
You shouldn't have a <div> as a child of an <a>, use an <img src="..."/> instead.
EDIT:
If you have a spritesheet, then simply add display:block; for the anchor and it will behave just like a div.
Since you are using a CSS Sprite, I would suggest placing the <a> inside the <div> (proper way to do it) and add some css:
HTML
<div class="icon-backbtn">
</div>
CSS
.icon-backbtn a {
display:block;
cursor:pointer;
text-decoration:none;
text-indent:-9999px;
}
The CSS sets the link to be a block element, thus occupying the width and height of the div. The remaining styles are to prevent the regular link behavior for texts, since you are using an image.

Make a div into a link

I have a <div> block with some fancy visual content that I don't want to change. I want to make it a clickable link.
I'm looking for something like <div> … </div>, but that is valid XHTML 1.1.
Came here in the hope of finding a better solution that mine, but I don't like any of the ones on offer here. I think some of you have misunderstood the question. The OP wants to make a div full of content behave like a link. One example of this would be facebook ads - if you look, they're actually proper markup.
For me the no-nos are: javascript (shouldn't be needed just for a link, and very bad SEO/accessibility); invalid HTML.
In essence it's this:
Build your panel using normal CSS techniques and valid HTML.
Somewhere in there put a link that you want to be the default link if the user clicks on the panel (you can have other links too).
Inside that link, put an empty span tag (<span></span>, not <span /> - thanks #Campey)
give the panel position:relative
apply the following CSS to the empty span:
{
position:absolute;
width:100%;
height:100%;
top:0;
left: 0;
z-index: 1;
/* fixes overlap error in IE7/8,
make sure you have an empty gif */
background-image: url('empty.gif');
}
It will now cover the panel, and as it's inside an <A> tag, it's a clickable link
give any other links inside the panel position:relative and a suitable z-index (>1) to bring them in front of the default span link
You can't make the div a link itself, but you can make an <a> tag act as a block, the same behaviour a <div> has.
a {
display: block;
}
You can then set the width and height on it.
This is an ancient question, but I thought I'd answer it since everyone here has some crazy solutions. It's actually very very simple...
An anchor tag works like this -
EVERYTHING IN HERE TURNS INTO A LINK
Sooo...
<div id="thediv" />
Although I'm not sure if this is valid. If that's the reasoning behind spoken solutions, then I apologise...
Requires a little javascript.
But, your div would be clickable.
<div onclick="location.href='http://www.example.com';" style="cursor:pointer;"></div>
This option doesn’t require an empty.gif as in the most upvoted answer:
HTML:
<div class="feature">
</div>
CSS:
div.feature {
position: relative;
}
div.feature a {
position: absolute;
width: 100%;
height: 100%;
top: 0;
left: 0;
text-decoration: none; /* No underlines on the link */
z-index: 10; /* Places the link above everything else in the div */
background-color: #FFF; /* Fix to make div clickable in IE */
opacity: 0; /* Fix to make div clickable in IE */
filter: alpha(opacity=1); /* Fix to make div clickable in IE */
}
As proposed at http://www.digitalskydesign.com/how-to-make-an-entire-div-a-link-using-css/
This is a "valid" solution to achieving what you want.
<style type="text/css">
.myspan {
display: block;
}
</style>
<span class="myspan">text</span>
But most-likely what you really want is to have an <a> tag displayed as a block level element.
I would not advise using JavaScript to simulate a hyperlink as that defeats the purpose of markup validation, which is ultimately to promote accessibility (publishing well-formed documents following proper semantic rules minimizes the possibility the same document will be interpreted differently by different browsers).
It would be preferable to publish a web page that does not validate, but renders and functions properly on all browsers, including ones with JavaScript disabled. Furthermore, using onclick does not provide the semantic information for a screen reader to determine that the div is functioning as a link.
The cleanest way would be to use jQuery with the data-tags introduced in HTML. With this solution you can create a link on every tag you want. First define the tag (e.g. div) with a data-link tag:
<div data-link="http://www.google.at/">Some content in the div which is arbitrary</div>
Now you can style the div however you want. And you have to create also the style for the "link"-alike behavior:
[data-link] {
cursor: pointer;
}
And at last put this jQuery call to the page:
$(document).ready(function() {
$("[data-link]").click(function() {
window.location.href = $(this).attr("data-link");
return false;
});
});
With this code jQuery applys a click listener to every tag on the page which has a "data-link" attribute and redirects to the URL which is in the data-link attribute.
Not sure if this is valid but it worked for me.
The code :
<div style='position:relative;background-color:#000000;width:600px;height:30px;border:solid;'>
<p style='display:inline;color:#ffffff;float:left;'> Whatever </p>
<a style='position:absolute;top:0px;left:0px;width:100%;height:100%;display:inline;' href ='#'></a>
</div>
To make thepeer's answer work in IE 7 and forward, it needs a few tweaks.
IE will not honour z-index if the element is has no background-color, so the link will not overlap parts of the containig div that has content, only the blank parts. To fix this a background is added with opacity 0.
For some reason IE7 and various compatibility modes completely fail when using the span in a link approach. However if the link itself is given the style it works just fine.
.blockLink
{
position:absolute;
top:0;
left: 0;
width:100%;
height:100%;
z-index: 1;
background-color:#ffffff;
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
filter: alpha(opacity=0);
opacity:0;
}
<div style="position:relative">
<some content>
<a href="somepage" class="blockLink" />
<div>
you could also try by wrapping an anchor, then turning its height and width to be the same with its parent. This works for me perfectly.
<div id="css_ID">
</div>
An option that hasn't been mentioned is using flex. By applying flex: 1 to the a tag, it expands to fit the container.
div {
height: 100px;
width: 100px;
display: flex;
border: 1px solid;
}
a {
flex: 1;
}
<div>
Link
</div>
This worked for me:
HTML:
<div>
WHATEVER YOU WANT
<a href="YOUR LINK HERE">
<span class="span-link"></span>
</a>
</div>
CSS:
.span-link {
position:absolute;
width:100%;
height:100%;
top:0;
left: 0;
z-index: 9999;
}
This adds an invisible element (the span), which covers your entire div, and is above your whole div on the z-index, so when someone clicks on that div, the click is essentially intercepted by your invisible "span" layer, which is linked.
Note: If you're already using z-indexes for other elements, just make sure the value of this z-index is higher than anything you want it to rest "on top" of.
why not? use <div></div> works fine in HTML5
This example worked for me:
<div style="position: relative; width:191px; height:83px;">
</div>
This post is Old I know but I just had to fix the same issue because simply writing a normal link tag with the display set to block does not make the whole div clickable in IE. so to fix this issue far simpler than having to use JQuery.
Firstly let us understand why this happens: IE wont make an empty div clickable it only make the text/image within that div/a tag clickable.
Solution: Fill the div with a bakground image and hide it from the viewer.
How?
You ask good questions, now listen up.
add this backround style to the a tag
> "background:url('some_small_image_path')
> -2000px -2000px no-repeat;"
And there you have it the whole div is now clickable. This was the best way for me cause Im using it for my Photo Gallery to let the user clik on one half of the image to move left/right and then place a small image as well just for visual effects. so for me I used the left and right images as background images anyway!
Just have the link in the block and enhance it with jquery. It degrades 100% gracefully for anyone without javascript. Doing this with html isn't really the best solution imho.
For example:
<div id="div_link">
<h2>The Link and Headline</h2>
<p>Some more stuff and maybe another link.</p>
</div>
Then use jquery to make the block clickable (via web designer wall):
$(document).ready(function(){
$("#div_link").click(function(){
window.location=$(this).find("a").attr("href"); return false;
});
});
Then all you have to do is add cursor styles to the div
#div_link:hover {cursor: pointer;}
For bonus points only apply these styles if javascript is enabled by adding a 'js_enabled' class to the div, or the body, or whatever.
This is the best way to do it as used on the BBC website and the Guardian:
I found the technique here:
http://codepen.io/IschaGast/pen/Qjxpxo
heres the html
<div class="highlight block-link">
<h2>I am an example header</h2>
<p>This entire box links somewhere, thanks to faux block links. I am some example text with a custom link that sits within the block</p>
</div>
heres the CSS
/**
* Block Link
*
* A Faux block-level link. Used for when you need a block-level link with
* clickable areas within it as directly nesting a tags breaks things.
*/
.block-link {
position: relative;
}
.block-link a {
position: relative;
z-index: 1;
}
.block-link .block-link__overlay-link {
position: static;
&:before {
bottom: 0;
content: "";
left: 0;
overflow: hidden;
position: absolute;
right: 0;
top: 0;
white-space: nowrap;
z-index: 0;
}
&:hover,
&:focus {
&:before {
background: rgba(255,255,0, .2);
}
}
}
<div> … </div>
Actually you need to include the JavaScript code at the moment,
check this tutorial to do so.
but there is a tricky way to achieve this using a CSS code
you must nest an anchor tag inside your div tag and you must apply this property to it,
display:block;
when you've done that,it will make the whole width area clickable (but within the height of the anchor tag),if you want to cover the whole div area you must set the height of the anchor tag exactly to the height of the div tag,for example:
height:60px;
this is gonna make the whole area clickable,then you can apply text-indent:-9999px to anchor tag to achieve the goal.
this is really tricky and simple and it's just created using CSS code.
here is an example: http://jsfiddle.net/hbirjand/RG8wW/
This work for me:
<div onclick="location.href='page.html';" style="cursor:pointer;">...</div>
You can give a link to your div by following method:
<div class="boxdiv" onClick="window.location.href='https://www.google.co.in/'">google</div>
<style type="text/css">
.boxdiv {
cursor:pointer;
width:200px;
height:200px;
background-color:#FF0000;
color:#fff;
text-align:center;
font:13px/17px Arial, Helvetica, sans-serif;
}
</style>
You can make surround the element with a href tags or you can use jquery and use
$('').click(function(e){
e.preventDefault();
//DO SOMETHING
});
This is the simplest way.
Say, this is the div block I want to make clickable:
<div class="inner_headL"></div>
So put a href as follows:
<a href="#">
<div class="inner_headL"></div>
</a>
Just consider the div block as a normal html element and enable the usual a href tag.
It works on FF at least.
I pulled in a variable because some values in my link will change depending on what record the user is coming from.
This worked for testing :
<div onclick="location.href='page.html';" style="cursor:pointer;">...</div>
and this works too :
<div onclick="location.href='<%=Webpage%>';" style="cursor:pointer;">...</div>
While I don't recommend doing this under any circumstance, here is some code that makes a DIV into a link (note: this example uses jQuery and certain markup is removed for simplicity):
<script type="text/javascript" src="jquery-1.3.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("div[href]").click(function () {
window.location = $(this).attr("href");
});
});
</script>
<div href="http://www.google.com">
My Div Link
</div>
If you can use bootstrap, one simple solution is to use bootstrap .stretched-link.
https://getbootstrap.com/docs/4.3/utilities/stretched-link/
Sample Code
<div class="card" style="width: 18rem;">
<img src="..." class="card-img-top" alt="...">
<div class="card-body">
<h5 class="card-title">Card with stretched link</h5>
<p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
Go somewhere
</div>
</div>
Soviut's answer was not sufficient for me. I had to use
a { display: inline-flex; }
to remove baseline artifacts, when using just a img in the a.
Enclosing your div inside an anchor tag <a href></a> works like charm:
<a href="">
<div>anything goes here will turn into a link</div>
</a>
My smarty pants answer:
"Evasive answer to: "How to make block level element a hyperlink and validate in XHTML 1.1"
Just use HTML5 DOCTYPE DTD."
Didn't actually hold true for ie7
onclick="location.href='page.html';"
Works IE7-9, Chrome, Safari, Firefox,
if just everything could be this simple...
#logo {background:url(../global_images/csg-4b15a4b83d966.png) no-repeat top left;background-position:0 -825px;float:left;height:48px;position:relative;width:112px}
#logo a {padding-top:48px; display:block;}
<div id="logo"></div>
just think a little outside the box ;-)
