I have twp elements inside my Div,both have same class name. I want to hide my first element with the class name .cart. I am using the below code.
.component-bottom .component-basket + .cart{
display:none;
}
<div class="component-bottom">
<div class="component-basket">
<div class="cart">
</div>
<div class="cart">
</div>
</div>
</div>
Am I using the correct code?
You can use a direct child selector for the .cart element:
.component-bottom .component-basket > .cart
{
display:none;
}
Now you only want the first element of this selector. There isn't an original selector for this, but you can make a overwrite selector for this.
You can overwrite all but the first one ElementA ~ ElementB:
.component-bottom .component-basket > .cart ~ .cart
{
display:block;
}
This search for all .cart elements inside .component-basket where ANY previous adjacent sibling is .cart. The first of the element doesn't have a previous sibling of this class, so it would not be selected.
This is called a general sibling selector.

This should support IE7 and above:
Note Requires Windows Internet Explorer 7 or later.

an easier solution commented by #jrConway:
Make it display: block by default and use:
.component-bottom .component-basket > .cart:first-child
{
display: none;
}
Example
Note that this only work when you use ONLY .cart as child element. Whenever an other class is at the first 'place' it will not work.
Using adjacent sibling selector won't work here, as your element is nested inside .component-basket and hence it fails.. Simple way is to call a class on the element you want to hide, if you cannot change the DOM than you can use first-child or nth-of-type(1)
.component-bottom .component-basket div.cart:nth-of-type(1) {
display:none;
}
Demo
As #Vucko already commented, nth-of-type() is a CSS3 spec pseudo..
Hence if you want to support legacy browsers, you can use Selectivizr,
this will save you a lot of classes/ids.
Stick this in your CSS file:
.hide {
display: none;
}
Then add that class to whatever element you want hidden like so:
<div class="component-bottom">
<div class="component-basket">Foo</div>
<div class="component-basket cart hide">Foo</div>
</div>
The advantage of this method is that you get to re-use that "hide" class anywhere you want.
As understood, check this might help
CSS
.cart{
display:none;
}
.component-bottom .component-basket
{
//some common properties
}
HTML
<div class="component-bottom">
<div class="component-basket cart">component-basket Hidden div</div>
<div class="component-basket">component-basket visible div</div>
</div>
This will hide the div with the cart class (the First div)

I have the following code:
<div class = "badge">
<div class = "badge-header">
</div>
</div>
What's the proper way to style badge-header in css?
Is it
.badge .badge-header {
}
or
.badge-header {
}
also how do we structure our css names? How do we structure our divs and what selectors should we use for each above?
If you have a div inside a div, what is the naming convention that we should stick to in CSS?
Both
but the first will apply the style only when the "badge-header" is inside of a "badge"
in the second will apply for all "badge-header" elements.
See example: https://jsfiddle.net/6bvLtqLw/
CSS
.badge-header{
color:blue;
}
.badge .badge-header{
background-color: yellow;
}
HTML
<div class="badge">
<div class="badge-header">
inside
</div>
</div>
<div class="badge-header">
outside
</div>
Both work
.badge .badge-header {
}
above one applies style to those elements with class '.badge-header' AND are under elements with class '.badge'
.badge-header {
}
and the above one applies style to all the elements with class '.badge-header' regardless of element's position in DOM.
Both
but the first will apply the style only when the "badge-header" is inside of a "badge"
.badge .badge-header {
}
in the second will apply for all "badge-header" elements.
.badge-header {
}
The first variant obviously will only style .badge-header if used in the context of a .badge. The second will apply to all .badge-headerregardless of their context.
If you are certain .badge-header will never need to be used outside of .badge, you go with variant two as it is shorter and more concise.
If it might be useful to reuse the .badge-header in different context than only .badge, then use *both variants. Put all styles that all .badge-header have in common in .badge-header { ... }. Put the context-dependent styles in .badge .badge-header { ... }.
I want to apply some CSS to the last blog-post. The problem is that the last element in the div 'blog-posts' is the same type of element as the 'blog-post' divs.
I've tried:
last-of-type
last-child
HTML:
<div class="blog-posts">
<div class="blog-post"></div>
<div class="blog-post"></div>
<div class="blog-post"></div>
<div class="blog-post"></div>
<div class="f03-456245"></div>
</div>
CSS:
.blog-post:last-child{
//do some css
}
Last element using .class is not possible. In your case you can use nth-last-child property.
.blog-posts div:nth-last-child(2) {
background: #ff0000;
}
DEMO
You may have to do like this:
.blog-posts div:last-child{
//do some css
}
It is assuming div is the element. It applies for anyother element type p , span etc...
I would like to select the first div called "aProduct" but I'm a bit confused on how to do this. I already tried this:
<div id="kasticketProducts">
<div class="aProductHeader"></div>
<div class="aProduct"></div>
<div class="aProductHeader"></div>
<div class="aProduct"></div>
</div>
This is my current CSS:
#kasticketProducts:first-child .aProduct {
margin-top: 30px;
background: red;
}
#kasticketProducts:first-child .aProduct
Using above css means first it'll search for id with kasticketproducts in that first-child, here first child refer to aProductHeader from here you are trying to search aProduct but it is not there.
Actually from DOM hierarchy aProduct class div is at second child this will be referred in css as nth-child(2) here and no need of again .aProduct .So the final solution for this is write as #kasticketProducts div:nth-child(2)
First, whats the difference?
From MDN :
:first-child()
The :first-child CSS pseudo-class represents any element that is the first child element of its parent.
:first-of-type()
The :first-of-type CSS pseudo-class represents the first sibling of its type in the list of children of its parent element.
So inshort, :first-child() is somewhat a loose pseudo selector compared to :first-of-type()
Unfortunately :first-child or :first-of-type doesn't respect classes or ids, they are only concerned with the DOM elements. So if you do something like, will fail
#kasticketproducts div.aProduct:first-of-type {
color: red;
}
So in this case the best you can do with CSS is use :nth-of-type() with 2 as a value, now obviously it will fail if your element doesn't have a class of aProduct
#kasticketproducts div:nth-of-type(2) {
color: red;
}
Demo
OR
you can use adjacent selector with :first-of-type()
#kasticketproducts div:first-of-type + div {
color: red;
}
Demo
Second solution is MORE COMPATIBLE as far as IE is concerned
DEMO
Code is not working because aProductHeader class is before first occurrence of aProduct class.
See demo.
You can't target the first element of a class, but you can target the elements that come after, so you can set the styles on all the aProduct elements and then override it on all aProduct that comes after the first one using the ~ opreator:
#kasticketproducts .aProduct {
margin-top: 30px;
background: red;
}
#kasticketproducts .aProduct ~ .aProduct {
margin-top: 0;
background: none;
}
Demo: http://jsfiddle.net/a9W5T/
You can use
:first-child, :nth-of-type(1), :first-of-type or :nth-child(1n)
And why your code donst work, is because you use:
#kasticketProducts:first-child .aProduct
this will take the first element #kasticketProducts, use this instead: #kasticketProducts .aProduct:nth-child(2) {
color: red;
} <-- This will take the first element .aProduct inside your ID element
Another solution would be to style .aProduct, and then override the style for any succeeding occurrences of .aProduct using the general sibling combinator:
#kasticketProducts .aProduct {
// effectively becomes the style for the first occurrence of .aProduct
}
#kasticketProducts .aProduct ~ .aProduct {
// overrides the style set above for all occurrences of .aProduct,
// apart from the first
}
The biggest advantage of this approach is that it doesn't rely on the structure of the markup.
General sibling selectors on MDN
Here's an example
Check the #id, it's case sensitive
Also, be careful with quotes, you are not closing them.
<div id="kasticketProducts">
<div class="aProductHeader">aaa</div>
<div class="aProduct">aaa</div>
<div class="aProductHeader">aaaa</div>
<div class="aProduct">aaa</div>
For the first .aProduct get selected:
#kasticketProducts .aProduct:nth-child(2) {
/* your styles */
}
Sorry for that, thought was for getting the first kasticketProduct. Apologizes.
Hope you can help me with this CSS trick.
Basically what I need is this kind of CSS
if 'container' has sibling 'mySibling' {
#myDiv{
}
}
if 'container' has no sibling {
#myDiv{
}
}
For this HTML
<div id="mySibling"></div>
<div id="container">
<div id="myDiv"></div>
</div>
sibling sometimes will not be present, and I need different css for myDiv in these cases
Any help would be appreciated, I tried doing + and ~ selectors but I don't think I have proper logic.
You can do something like this:
#mySibling + #container #myDiv {
background-color:blue;
}
Here is a fiddle showing it off: http://jsfiddle.net/Lzq3S/
Note, I've changed the ids to classes in the fiddle just to show the two sets of div elements, but you get the idea...
This breaks down to myDiv that is a child of container that is a sibling of mySibling.
First off, make sure your html is correct; in your example, you forgot to specify whether you're using an id or a class! Possible options for your html:
<div id="container">
<div class="mySibling"></div>
<div class="myDiv"></div>
</div>
or
<div id="container">
<div id="mySibling"></div>
<div id="myDiv"></div>
</div>
For the sake of your example, we'll use id's, even though some would say it's better practice to use classes
Now for the CSS.
The + and ~ selectors operate in slightly different ways. The + selects adjacent siblings, while the ~ selects all siblings. Because CSS doesn't handle logic quite the same way as actual programming languages, you can't check to see if a container holds a certain element before applying styles, but you can use the sibling selectors to style elements that are next to certain other elements.
My suggestion:
.container #myDiv {
/* Your styles for #myDiv */
}
.container #mySibling + #myDiv {
/* Your styles for #myDiv it is next to #mySibling.
Will override the styles a */
}
You can check out an example here: http://jsfiddle.net/8r2TZ/. Note, I specified "myDiv" as a class, because I used it more than once, and my CSS reflects that.
If you do need to have a CSS rule for each case without relying on overriding, it's still possible, since there's a selector for elements with no siblings:
#mySibling + #container > #myDiv {
}
#container:only-child > #myDiv {
}
(You can even achieve compatibility with old IEs by using :first-child in lieu of :only-child since #mySibling comes first.)
I have looked at several other questions but I can't seem to figure any of them out, so here is my problem: I would like to have a div or a span, when you hover over it an area would appear and would be like a drop down.
Such as I have an div, and I want to hover over it and have it show some info about the item I hovered over
<html>
<head>
<title>Question1</title>
<styles type="css/text">
#cheetah {
background-color: red;
color: yellow;
text-align: center;
}
a {
color: blue;
}
#hidden {
background-color: black;
}
a:hover > #hidden {
background-color: orange;
color: orange;
}
</styles>
</head>
<body>
<div id="cheetah">
<p>Cheetah</p>
</div>
<div id="hidden">
<p>A cheetah is a land mammal that can run up 2 60mph!!!</p>
</div>
</body>
</html>
But this ^ doesn't seem to work, I don't know why... and if there is a way to do that in CSS, I would like to know, but I want any and all suggestions.
You can achieve this in CSS only if the hidden div is a child of the element you use for hovering:
http://jsfiddle.net/LgKkU/
You cannot affect a non-child element using :hover from within CSS2, which is supported by all common browsers.
You can affect a sibling element using CSS2.1 selectors, like so:
a:hover + .sibling { ... }
However, this only works for direct siblings. This means you could have HTML like this:
<p>Cheetah <span class="sibling">Blah Blah Blah</span></p>
Notice that the a and the span are direct siblings.
Here's a fiddle showing the siblings working: http://jsfiddle.net/vUUxp/
However, not all browsers support the CSS2.1 sibling selectors, so you need to decide based on your target audience if you can use this or not.
Edit: Corrected my mistake on the CSS version for the + selector: it's 2.1 that defines it, not CSS3. I also added a link showing browser support. Otherwise, the answer is the same.
Or, if you're open to it, use jQuery.
Something like this would work:
$("#element") // select your element (supports CSS selectors)
.hover(function(){ // trigger the mouseover event
$("#otherElement") // select the element to show (can be anywhere)
.show(); // show the element
}, function(){ // trigger the mouseout event
$("#otherElement") // select the same element
.hide(); // hide it
});
And remember to wrap this in a DOM ready function ($(function(){...}); or $(document).ready(function(){...});).
You can absolutely do this in CSS3 now using the ~ adjacent sibling selector.
triggerSelector:hover ~ targetSelector {
display: block;
}
For example, if you want a tooltip to appear when hovering over an adjacent button:
.button:hover ~ .tooltip {
display: block;
}
