How to make a div invisible without commenting it out? - css

Is it possible to make a div invisible without commenting it out? If so, how?

You need to hide that with CSS:
div { /* this will hide all divs on the page */
display:none;
}
If it is a particular div with certain class or id, you can hide it like:
<div class="div_class_name">Some Content</div>
CSS:
div.div_class_name { /* this will hide div with class div_class_name */
display:none;
}
Or
<div id="div_id_name">Some Content</div>
CSS:
div#div_id_name { /* this will hide div with id div_id_name */
display:none;
}
Note: You need to wrap CSS tyles in between <style type="text/css"></style> tags, example:
<style type="text/css">
div#div_id_name {
display:none;
}
</style>
More Information :)

You can do this by inline style
<div style="display:none"></div>
or by defining CSS Style like
In css add
.HideableDiv{display:none;}
and in your HTML write
<div class="HideableDiv" ></div>

Its Easy. The only thing you need is, adding a style to it, like following example shows:
CSS:
<style type="text/css">
div.myInvisibleDiv {
overflow: hidden;
visibility: hidden;
height: 0;
width: 0;
}
</style>
HTML:
<div class="myInvisibleDiv"><p>My invisible content</p></div>
This div, and it content does definitely not show, and it wont disturb surrounding elements.

if you want it to be essentially gone from your layout:
.element_class {
display:none;
}
if you want to just make it invisible (but still keeping it's space seemingly empty)
.element_class {
visibility: hidden;
}
and then your element (if a div) would look like this:
<div class="element_class"></div>
basically anything you add the class="element_class" to will be either invisible or completely hidden.

position: absolute;
left: -99999px; /* big number */
will make the content accessible to most screen readers but will render the element off-screen.

May be, its not the required solution, but you can tackle this kind of issues by these little tricks.
You can use jQuery to achieve the solution.
If you want to totally hide/show the div, then you can use:
$('#my_element').show()
$('#my_element').hide()
Or if you want that your div become invisible and its still existing in the page, then you can use efficient trick:
$('#my_element').css('opacity', '0.0'); // invisible Maximum
$('#my_element').css('opacity', '1.0'); // visible maximum

Applying CSS3 to pseudo-class first-child

I have markup that goes something like this
<div class='wrap'>
<div class='container'>
Body Container content
</div>
<div class='container'>
Footer Container content
</div>
</div>
I want to display a header containing, amongst other things, a logo above the first, body, container. This I accomplished by defining
.container::before
{
background-image(url(path/to/image.jpg);
background-size:cover;
content:'';
}
The above works. The problem is that the logo ends up not onlyu above the body content but also above the footer content which is not quite the desired result. I have played around with various combinations of
.container::before:nth-of-child(1)
{
}
.container:nth-of-child(1)::before
{
}
but I haven't quite found the right syntax to target the ::before pseudo element for the first .container instance. I hope that someone here will be able to tell me how it should be done.
If the worst comes to the worst I can do it with a spot of jQuery but I would like to avoid that.
Would you consider using <main> W3 4.4.14 The main element and <footer> 4.4.9 The footer element per HTML5 elements with class of .container on each? That way you can reference/target those elements without psuedo elements
main::before
{
background-image(url(path/to/image.jpg);
background-size:cover;
content:'';
}
This way the header/logo you are looking for would only appear above the first container only. Then if you need to apply pseudo elements to <footer> you could do something like:
footer::before
{
background-image(url(path/to/image.jpg);
background-size:cover;
content:'';
}
OK so I'll add another answer because it doesn't appear that anyone has solved all of your issues.
First, there is a typo in your css: background-image(url(path/to/image.jpg) is missing the closing paren.
To do what you want, however, there is a simple css selector :). In your example, you try nth-to-child(), but the correct syntax for what you want is nth-child(). Look below for two options, with a working demo.
.container:first-child:before
{
display: block;
content: "Before Element";
/* other styling that you choose*/
}
/* the following selector will also work
.container:nth-child(1):before
{
display: block;
content: "Before Element";
}
*/
<div class='wrap'>
<div class='container'>
Body Container content
</div>
<div class='container'>
Footer Container content
</div>
</div>
Note that the display: block; part is so that the before content appears on it's own line, since :before elements by default are display: inline-block;.
I dont think that there is a way to making it work with nth-of-child, but it will definitely work with first-child (if you always need it only in the first element with class .container):
.container:first-child:before
{
background-image(url(path/to/image.jpg);
background-size:cover;
content:'';
}
My first thought here is that there should be an additional class for the header, or use the <header> and <footer> elements in place of divs. For example:
<div class="wrap">
<div class="container header">
Header
</div>
<div class="container footer">
Footer
</div>
</div>
and
.header::before {
// stuff to make your logo
}
However, if for some reason you can't change the html, then the :first-child selector should work for your needs, as others have answered.
If you want to use nth-child() you need to add it to the parent of the element that you want to select. In this case .wrap.
.wrap:nth-child(1):before
{
background-image(url(path/to/image.jpg);
background-size:cover;
content:'';
}

How to show only the div with id while hiding other divs using CSS only

I was trying to parse from a complicated html page, but someone told me a better way is to inject my own css into that html. So I have the following situation:
<html>
<head>
<link rel="stylesheet" type="text/css" href="test.css" />
</head>
<body>
<div>
layer one div
<div id="center">
layer two div
<div>
layer three div
</div>
</div>
</div>
</body>
</html>
As you can see the div with id is sandwiched between a parent div and a child div.
I wonder if it is possible to hide the parent and child, making the page only show layer two div line. I try doing
div { display: none; }
div#center { display: inline;}
but without success.
I am using the indent method now, thank you for all the help, guys! : )
Here is kind of a hack, but it works:
HTML
<div>
layer one div
<div id="center">
layer two div
<div>
layer three div
</div>
</div>
</div>
CSS
div {
text-indent: -9999px;
}
div#center {
text-indent: 0px;
}
div#center div {
display: none;
}
Fiddle: http://jsfiddle.net/fPdda/2/
As far as I know, there is no option to show element which is placed under hidden element. So CSS will not do the trick. The only possible option is use javascript, which move element which is supposed to be visible out of parent. This can be easily done with jQuery.
However I don't know why you need this and what you mean with word "parse". CSS will affect only what you see, but under "parse" I understand processing data - and for processing is not important how it is shown. Maybe if you specify more detailed what you need, I can help.
This method will not work. Sadly, because your displayed div is inside a hidden div, you're sunk if you're stuck with that markup. You could get fancy and use text-indent: -9999px instead of display: hidden, then text-indent: 0px on the one you want to show, but the negative indented elements will still take up vertical space. Alternately, you could use JS to duplicate the node and re-insert it into the DOM at a different point, maybe inside an element that isn't hidden.
var nodeToShow = document.getElementById('center').cloneNode();
nodeToShow.setAttribute('id', 'centerClone');
document.body.appendChild(nodeToShow);
I don't think that is possible. Hiding the parent div takes precedence on the child, so your child with id is visible but only in the scope of parent div which is hidden. In order to accomplish what you trying to do just wrap the parent text in a span and hide the span;
div span{
display:hidden;
}
div#center div{
display:hidden;
}
You can't hide a parent yet make a child element visible, it just doesn't work that way. I would suggest doing something like this:
<div class="layer-one">
<span class="layer-one">layer one div</span>
<div id="center">
layer two div
<div>
layer three div
</div>
</div>
</div>
.
div,
span.layer-one {
display: none;
}
div.layer-one,
div#center {
display: block;
}

CSS: move an element, overriding its position in the HTML

Let's say I have this HTML page:
<body>
<p id="alice">Alice</p>
<p id="bob">Bob</p>
</body>
and this pretend CSS syntax:
p#alice:before { p#bob }
In other words, I want to override the HTML using CSS, placing the Bob element ABOVE the Alice element. Why? Because in my case I can edit the CSS, and I cannot edit the HTML.
Bob doesn't have to actually occur before Alice in the DOM, but it does need to appear ABOVE Alice visually.
The only way to do this with pure CSS that is completely flexible is with flexbox.
http://jsfiddle.net/S9L3r/ (prefixes not included)
body {
display: flex;
flex-flow: column nowrap;
}
#alice {
order: 2;
}
http://caniuse.com/#feat=flexbox
You can always do this with jQuery if you are able to add the code.
$('#bob').insertBefore('#alice');
Thats easy but ugly and you shouldnt do it.
However here is how to do it:
http://jsbin.com/azevet/2/edit
<div class="first-in-dom">
Im first in DOM
</div>
<div class="second-in-dom">
Im second in DOM
</div>
div {
height:100px;
border:solid;
}
.first-in-dom, .second-in-dom {
position:relative;
}
.first-in-dom {
margin-bottom:-100px;
top:110px;
}

CSS - Style specific to single Element

I'm using jQuery to add a Class to a few elements.
I'm not new to adding classes, nor removing them. But I'm still somewhat intermediate with styles and any flexibility styles can perform to single elements.
Here's what's going on:
I have 2 Divs that I'm affecting with jQuery:
<div id="columnleft">stuff in here</div>
<div id="columncenter">bigger stuff in here</div>
In a nutshell, column left is about 155px wide, while columncenter is positioned relative to columnleft, with a margin-left of 162px
Here's my styles:
<style>
#columnleft {
float:left;
position:relative;
text-align:left;
width:155px;
}
#columncenter {
position:relative;
padding-bottom:50px
margin:0;
margin-left:162px;
}
</style>
I'm basically toggling these 2 divs with the jQuery examples below:
So far I've gotten these 2 separate instances to work:
$("#columnleft").hide();
$("#columncenter").css("margin","0px");
then........
$("#columnleft").show();
$("#columncenter").css("margin-left","162px");
Though this works, I'm not quite satisfied.
I'd prefer to create a class or two that I can use to toggle the hiding of columnleft, while also changing the margin-left at the same time.
It's all fine with the example above, when I'm only using jQuery. But there are times when a page loads, and the columnleft is meant to be hidden, and columncenter is meant to be expanded, from the beginning. Would be nice to not need jQuery to enter the scene at those moments.
All I could come up with is:
<style>
.disappear { display:none; }
.maximize { margin:0px; margin-left:0px; }
</style>
When the page loads:
<div id="columnleft" class="disappear">stuff in here</div>
<div id="columncenter" class="maximize">bigger stuff in here</div>
it seems that columncenter is ignored. (columnleft indeed does disappear)
Also, toggling with jquery, the same result occurs.
Column Center hates me!
Does anyone see where I'm missing the mark?
View JSFiddle: http://jsfiddle.net/tuanderful/bTZq8/
What if you had another div that contains both #columnleft and #columncenter, and has a class of .hide-left or .show-left:
<div class="hide-left">
<div id="columnleft">stuff in here</div>
<div id="columncenter">bigger stuff in here</div>
</div>
​
Then add the following CSS:
.show-left #columnleft {
display: block;
}
.show-left #columncenter {
margin-left: 162px;
}
.hide-left #columnleft {
display: none;
}
.hide-left #columncenter {
margin-left: 0;
}
You can update your jQuery to simply toggle the .hide-left or .show-left classes on the parent container.
What I did here is similar to adding .disappear and .maximize styling, but I added a bit of context around the two columns. The neat thing is that all of the styling is handled purely by CSS - when you want to show or hide your sidebar, you only need JavaScript to update the state of the container; that is, change the class in the container from hide to show or vice versa.
You need to put !important on the css styling.
.maximize {
margin-left: 0px !important;
}
That makes it so that it overrides any other styling of the same kind. Check it out here.
There is an order of importance in CSS. An id # is considered more important than a class . (there can only be one id and many classes after all). So if you are trying to override an id with a class, you need to use !important.
each type of selector in css is weighted differently id being higher than classes and classes being higher than objects
to fix your problem make the selector as such
#columncenter.maximize
this will overwrite the rule before it
don't use !important while it might work now it can be hard to find out why something is being overridden later on

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"

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 ;-)
