I have html script like :
<html>
<head></head>
<body>
<div id="div1"></div>
<div id="div2"></div>
</body>
</html>
then I want to access the div by url, if url is:
example.com#div1
I want to hide div2 and if url is:
example.com#div2
then I want to hide div1
How do I solve that with css?
It is possible through CSS using pseudo selector
<html>
<head>
<style type="text/css">
.my-div {
background-color: green;
display: none;
height: 100px;
width: 100px;
}
.my-div:target {
display: block;
}
</style>
</head>
<body>
<div id="div1" class="my-div">Div 1</div>
<div id="div2" class="my-div">Div 2</div>
</body></html>
Make sure you always hit with #div1 in url e.g. example.com/#div1 or example.com/#div2 else it will show blank page
I did this recently, don't think you can do with CSS only.
this will load correct div on page load, including when the user uses back in browser.
<script>
$(document).ready(function() {
if (window.location.hash) {
var hash = window.location.hash.substring(1);
changeTab(hash);
}
else {
changeTab('div1');
}
});
function changeTab(divNo) {
$('.divclass').hide();
$('#' + divNo).show();
window.location.hash = '#'+divNo;
}
</script>
if you use a button to change divs just use:
onclick="changeTab('div1');"
set your div's class attribute to a type like 'divclass'
How to target outer div based on url?
The CSS pseudo-class :target is perfectly suited to this:
div {
float:left;
width: 300px;
height: 150px;
}
#div1, #div2 {
display:none;
line-height: 150px;
color: rgb(255,255,255);
font-size: 72px;
text-align: center;
font-weight: bold;
}
#div1 {
background-color: rgb(255,0,0);
}
#div2 {
background-color: rgb(0,0,255);
}
#div1:target, #div2:target {
display:block;
}
<div>
<p>Display Div1 (but not Div 2)</p>
<p>Display Div2 (but not Div 1)</p>
</div>
<div id="div1">Div 1</div>
<div id="div2">Div 2</div>

I have a header with 3 links, all linking to a specific div with a corresponding id:
body {
font-size: 32px;
}
.links {
display: flex;
a {
padding: 10px;
}
}
.box:not(:target) {
display: none;
}
#box1 {
background-color: crimson;
}
#box2 {
background-color: darkgreen;
}
#box3 {
background-color: gold;
}
<div class="links">
Box1
Box2
Box3
</div>
<div class="box" id="box1">Box1 content</div>
<div class="box" id="box2">Box2 content</div>
<div class="box" id="box3">Box3 content</div>
I want to use the CSS pseudo class to turn the selected element from display:none to display:block when targetted. I achieved this using .box:not(:target) { display:none }.
The problem is that I would like to default the boxes to show the first box (#box1) if :target does not exist amongst the three boxes with css only if possible, any help would be greatly appreciated!
Follow below the snippet, hope your problem will fix with html and css,
body {
font-size: 32px;
}
.links {
display: flex;
a {
padding: 10px;
}
}
.box:not(:target) {
display: none;
}
#box1{
display: block;
}
#box2:target ~ #box1,
#box3:target ~ #box1{
display: none;
}
#box1 {
background-color: crimson;
}
#box2 {
background-color: darkgreen;
}
#box3 {
background-color: gold;
}
<div class="links">
Box1
Box2
Box3
</div>
<div class="box" id="box2">Box2 content</div>
<div class="box" id="box3">Box3 content</div>
<div class="box" id="box1">Box1 content</div>
the box1 is default and when you trigger the box2, box3 you can see box1 will get display none.
mainly it's working for "general sibling selector (~)"
Create new css class called BoxControl consider this in all <a> elements for trigger show/hide event.
Then Add .active css class and add it to default class list of the element you want to show in first view as shown bellow.
Finally, implement JS as for your HTML structure tell that is your best option otherwise you'll have to modify your HTML.
SCSS/JS

CSS/JS
// Capture all elements of <a> output should be in an array
var box = document.getElementsByClassName("boxControl");
// Create new variable i stands for index to be used in for loop
var i;
// Loop through all elements been found in box variable
for (i = 0; i < box.length; i++) {
// Add Event Listener of Click for <a> elements found in the variable box
box[i].addEventListener("click", function(e) {
// Add e in callback function trace the element triggered this event
// In other words, which button has been clicked
var clicked =
e.target.getAttribute("href");
// Tricky bit: As per your request they should be at least
// one default active element otherwise or else will not remove any active class
if (document.querySelector(".active")) {
document.querySelector(".active").classList.remove("active");
// Use value of captured attribute (href) to target and toggle the new active class
document.querySelector(clicked).classList.toggle("active");
// Not found any active css class (box)
} else {
var clicked = e.target.getAttribute("href");
document.querySelector(clicked).classList.toggle("active");
}

First off I'm having a tough time understanding the fundamentals of the hero-transition within Polymer. I am attempting to build a hero transition card like the one in the example provided by them, which can be found here.
Below I've built the mini card and I'm just trying to understand the transition and how the larger card works with the smaller one.
My specific question is, how does the transition bind to each element? Do I need to complete the CSS for both before I can begin playing with the core-animated-pages? Does having an embedded template matter?
Any guidance would be extremely helpful.

you are actually very close to a working transition with the code you have.
I've implemented a more complicated hero transition on my website and took some code from there to get yours to work.
<core-animated-pages transitions="hero-transition" selected={{page}}>
<section>
<paper-shadow z="1" id='paper_shadow' on-mouseover="{{raise}}" on-mouseout="{{lower}}" hero-p on-tap="{{transition}}">
<div id="chip_body" hero-id="chip_body" hero vertical layout center justified>
<div id="chip_top" flex>
<div id="coreImage">
<content select="#core-image"></content>
</div>
</div>
<div id="chip_bottom" vertical layout start-justified>
<div id='text'>
<content select="#chip_bottom"></content>
</div>
</div>
</div>
</paper-shadow>
</section>
<section id="page2">
<div id="card_container" hero-id="chip_body" on-tap="{{transition}}" hero></div>
</section>
</core-animated-pages>
I've made but a few adjustments.
First off, any hero parent element, with the hero-p attribute, should contain just that attribute. So no need for the quotation marks :)
<paper-shadow hero-p .. >
Every element that's part of the Hero transition, needs a hero attribute.
Again, without the quotation marks. <div id="chip_body" .. hero .. >
And the same thing goes for the element you're transitioning to.
<div id="card_container" .. hero .. >
I've put a working version of your code on my website.
There's page containing the <chip-card> element and a second page containing the working template file.

I want to hide a div con1 when i hover div con2 and vice versa. I am able to hide con2 when i hover con1 but can't do the same vice-versa. Why it is not working when i hover con2 to hide con1.
Below are the codes:
<html>
<head>
<title>Home</title>
<style type="text/css">
#con1{
float: left;
width: 500px;
height: 300px;
background: #f00;
}
#con2{
float:left;
width: 500px;
height: 300px;
background: #808;
}
#con1:hover ~#con2{
visibility:hidden;
}
#con2:hover ~#con1{
display:none;
}
</style>
</head>
<body>
<div id="con1">
</div>
<div id="con2">
</div>
</body>
</html>
Example: http://jsfiddle.net/mendesjuan/s8bbe/
I believe this is not possible with the general sibling selector as it only applies to elements after it in the html-structure. See more: http://css-tricks.com/child-and-sibling-selectors/
A possible (althought not especially elegant solution):
http://jsfiddle.net/s8bbe/4/
<div id="wrapper">
<div id="con1">
</div>
<div id="con2">
</div>
#con1{
float: left;
width: 500px;
height: 300px;
background: #f00;
}
#con2{
float:left;
width: 500px;
height: 300px;
background: #808;
}
#con1:hover ~#con2{
visibility:hidden;
}
#wrapper:hover #con1:not(:hover){
visibility:hidden;
}
Example: http://jsfiddle.net/s8bbe/5/
#KnutSv's solution is great. Here's an add-on if using more than 2 divs.
<div id="con-wrapper">
<div id="con1">
</div>
<div id="con2">
</div>
<div id="con3">
</div>
</div>
And a one-line css with :hover, :not(:hover).
#con1{
float: left;
width: 500px;
height: 300px;
background: #f00;
}
#con2{
float:left;
width: 500px;
height: 300px;
background: #808;
}
#con3{
float:left;
width: 500px;
height: 300px;
background: #606;
}
#con-wrapper:hover > div:not(:hover) {
visibility: hidden;
}
Using "> div" will target all #con-wrapper direct div children, which are not hovered, and hide them.
Use #con-wrapper:hover > div[id^=con]:not(:hover) if only cons needed to be targeted.
Putting the divs in one container div you can hide all contained divs on hoover, but not the actually 'hovered over' one with:
div:hover div {
visibility: hidden;
}
div:hover div:hover {
visibility: visible;
}
See demo: http://jsfiddle.net/TcPJZ/3/
EDIT: It actually works well for arbitrary number of divs (see demo).
Maybe you are using wrong selectors
try this
.con2:hover ~ div {display:none}
But this is "Hard code" if you will want to add more divs before con-2 they will be dissappearing too
I try it on jsfiddle and I get the problem.
When you have this:
<div id="con1">
</div>
<div id="con2">
</div>
Hover on "con1" works, but when you change the positions:
<div id="con2">
</div>
<div id="con1">
</div>
Now it's "con2" which is working and now not "con1".
So , I don't know how to fix it, but I can tell you about make it by Javascript/Jquery.
I think that can be solve the problem.
CSS doesn't support previous sibling selection. If you still want to have a previous sibling selector then you should look in to javascript.
var con1 = document.getElementById('con1');
var con2 = document.getElementById('con2');
function displayElem(el, property, value){
el.style[property] = value;
}
con1.onmouseover = displayElem.bind(null, con2, 'display', "none");
con1.onmouseout = displayElem.bind(null, con2, 'display', "");
con2.onmouseover = displayElem.bind(null, con1, 'visibility', "hidden");
con2.onmouseout = displayElem.bind(null, con1, 'visibility', "");
Working Fiddle
In the above fiddle, I even moved the next sibling selection to javascript so that to let you keep the code structured. if you don't want to do so, then happily don't events to the first element :)
it will be easily done by using below code using jquery , why you depend only on css
$("#con1").hover(function(){
$("#con2").css("visibility","hidden");
},function(){
$("#con2").css("visibility","visible");
});
here is the working sample http://jsfiddle.net/5jRXm/
I have this HTML code:
<div data-width="70"></div>
I want to set it's width in CSS equal to the value of data-width attribute, e.g. something like this:
div {
width: [data-width];
}
I saw this was done somewhere, but I can't remember it. Thanks.
You need the attr CSS function:
div {
width: attr(data-width);
}
The problem is that (as of 2021) it's not supported even by some of the major browsers (in my case Chrome):
You cant pass data attribute value directly in to css without pseudo type content.
Rather you can do this way.. CHECK THIS FIDDLE
<div data-width="a"></div><br>
<div data-width="b"></div><br>
<div data-width="c"></div>
CSS
div[data-width="a"] {
background-color: gray;
height: 10px;
width:70px;
}
div[data-width="b"] {
background-color: gray;
height: 10px;
width:80px;
}
div[data-width="c"] {
background-color: gray;
height: 10px;
width:90px;
}
Inline CSS variables are almost as declarative as data attributes, and they are widely supported now, in contrast to the attr(). Check this out:
var elem = document.getElementById("demo");
var jsVar = elem.style.getPropertyValue("--my-var");
function next() {
jsVar = jsVar % 5 + 1; // loop 1..5
elem.style.setProperty("--my-var", jsVar);
}
.d1 {
width: calc( var(--my-var) * 100px );
background-color: orange;
}
.d2 {
column-count: var(--my-var);
}
<button onclick="next()">Increase var</button>
<div id="demo" style="--my-var: 2">
<div class="d1">CustomWidth</div>
<div class="d2">custom columns number custom columns number custom columns number custom columns number custom columns number custom columns number custom columns number</div>
</div>
Another approach would be using CSS Custom Properties with style element to pass values from HTML to CSS.
div {
width: var(--width);
height: var(--height);
background-color: var(--backgroundColor);
}
<div
style="
--width: 50px;
--height: 25px;
--backgroundColor: #ccc;
"
></div>
<div
style="
--width: 100px;
--height: 50px;
--backgroundColor: #aaa;
"
></div>
CSS is static styling information about specific html element and not the other way around. If you want to use CSS to set the width of your div I suggest you do with the use of classes:
HTML:
<div class="foo"></div>
CSS:
.foo {
width: 70px;
}
jsFiddle
I'm just having fun with this, but a jQuery solution would be something like this:
HTML
<div class='foo' data-width='70'></div>
<div class='foo' data-width='110'></div>
<div class='foo' data-width='300'></div>
<div class='foo' data-width='200'></div>
CSS
.foo {
background: red;
height: 20px;
margin-bottom: 10px;
width: 0; /** defaults to zero **/
}
jQuery
$(document).ready(function(){
$('.foo').each(function(i) {
var width = $(this).data('width');
$(this).width(width);
});
});
Codepen sketch here: http://cdpn.io/otdqB
KIND OF AN UPDATE
Not what you're looking for, since you want to pass a variable to the width property. You might as well use a class in this case.
HTML
<div data-width='70'>Blue</div>
CSS
div[data-width='70'] {
width: 70px;
}
Sketch here: http://cdpn.io/jKDcH
<div data-width="70"></div>
use `attr()` to get the value of attribute;
div {
width: attr(data-width);
}
can you try this
$(function(){
$( "div" ).data( "data-width" ).each(function(this) {
$(this).width($(this..data( "data-width" )))
});
});
What is the correct way to select a link of a certain class within a body of specific class. For example my body has the class "abc" and my link has the class "efg", what would my css code look like? (I'm trying to create active links for a Magento block)
body.body_class a.link_class
This question is a bit basic - you should try to learn this stuff a bit.
You have to do some research
body.abc a.efg {
rules
}
even w3c can help you with that
You should write something like this:
.abc .efg {
/*Your CSS Rules*/
}
