I want to add css for my child class - html

How can I add CSS to my child of child element, i tried this code
.inactive-property {
background-color: #e85050;
color: white!important;
}
.inactive-property > .mng-prop-span{
color: white!important;
}
My DOM element like
<div class="inactive-property">
<div class="a">
<div class="aa">
<div class="mng-prop-span"></div>
</div>
</div>
<div class="b"></div>
</div>
I want to apply css on class mng-prop-span

The element that is a member of the mng-prop-span class is not a child of the element that is a member of the inactive-property. It is a great-grandchild.
Use a descendant combinator (a space: ) and not a child combinator (>).

.inactive-property > .mng-prop-span{
color: white!important;
}
The first line is not correct. > is used for a quick next child. Better you try it without >

You can do this simply like that
.inactive-property .mng-prop-span{
color: white;
}
It will match the .mng-prop-span class inside .inacvite-property class
You do not have to use important property here.
If you want to match only those elements that are child of "aa" element inside "inactive-property" you can do this like that
.inactive-property .aa > .mng-prop-span{
color: white;
}

see here jsfiddle
code :
.inactive-property {
background-color: #e85050;
color: white;
height:100px;
width:100px;
}
.inactive-property .mng-prop-span{
color: black;
}
.mng-prop-span it's not a direct child of the .inactive-property , but it's a descendant so instead of > use .inactive-property .mng-prop-span{ with a simple space between the two
2.> is a child selector that selects children that are directly under the parent
i suggest you don't use !important only when it's absolutely necessary

EDIT : could you explain the downvote ? ( the one who downvoted ) . i am very curious

apply css rule to everything apart from one tag

I want to apply a css rule to everything (* { color: red; }).
But, how can I do this without the need for Javascript or applying a class to everything I want it to be applied to?
Something like:
*:not-type(div) {
color: red;
}
And the document would be:
<span>this is red</span>
<span>this is red</span>
<div>this is not red</div>
Try like this:
*{
color: red;
}
div{
color: blue;
}
To select everything except div elements you would write:
:not(div) {
color: red;
}
Caveat: while this rule correctly selects all elements except div, it does not prevent a div from inheriting red color from its parent which is the default behavior.
Try like this:
:not(div){
color: red;
}

Reset css style color property

Is it possible to define a style this way? The class child in this example is red unless it's wrapped in a parent class where I want it to reset so that it takes the color defined in the style attribute of parent.
.child {
color: red;
}
.parent > .child {
color: _clear_;
}
<div class="parent" style="color:blue;">
<div class="child">Some Text</div>
</div>
I think color: inherit; for .parent > .child is what you are looking for:
.child {
color: red;
}
.parent > .child {
color: inherit;
}
<div class="parent" style="color:blue;">
<div class="child">This will be blue</div>
</div>
<br/>
<div class="child">This will still be red</div>
JSFiddle for sample
If you are using valid selectors, like in your example, you want to use inherit:
.child {
color: red;
}
.parent > .child {
color: inherit;
}
However, if you were looking for something more complicated like "style the child based on the parent not having a specific attribute", that may be out of reach with pure CSS. Also, some child elements may not be able to logically inherit a style from a parent, so be sure to set the "parent" style rule on a parent that the child can inherit from and that you have in mind for the rule (so not so high up the chain that you didn't intend that color for that scenario). For instance, in the above example if the parent did not have the inline style rule, there would be no color rule, so the child would pick up a value from somewhere higher up.

How to use first-child?

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.

How do I select an element that has a certain class?

My understanding is that using element.class should allow for a specific element assigned to a class to receive different "styling" than the rest of the class. This is not a question about whether this should be used or not, but rather I'm trying to understand how this selector is intended to work. From looking at a ton of examples on the internet, I believe the syntax is correct and do not understand why this is not working.
Here is an example:
CSS:
h2 {
color: red;
}
.myClass {
color: green;
}
h2.myClass {
color: blue;
}
HTML:
<h2>This header should be RED to match the h2 element selector</h2>
<div class="myClass">
<h1>This header should be GREEN to match the class selector</h1>
<h2>This header should be BLUE to match the element.class selector</h2>
</div>
It should be this way:
h2.myClass looks for h2 with class myClass. But you actually want to apply style for h2 inside .myClass so you can use descendant selector .myClass h2.
h2 {
color: red;
}
.myClass {
color: green;
}
.myClass h2 {
color: blue;
}
Demo
This ref will give you some basic idea about the selectors and have a look at descendant selectors
h2.myClass refers to all h2 with class="myClass".
.myClass h2 refers to all h2 that are children of (i.e. nested in) elements with class="myClass".
If you want the h2 in your HTML to appear blue, change the CSS to the following:
.myClass h2 {
color: blue;
}
If you want to be able to reference that h2 by a class rather than its tag, you should leave the CSS as it is and give the h2 a class in the HTML:
<h2 class="myClass">This header should be BLUE to match the element.class selector</h2>
The element.class selector is for styling situations such as this:
<span class="large"> </span>
<p class="large"> </p>
.large {
font-size:150%; font-weight:bold;
}
p.large {
color:blue;
}
Both your span and p will be assigned the font-size and font-weight from .large, but the color blue will only be assigned to p.
As others have pointed out, what you're working with is descendant selectors.
h2.myClass is only valid for h2 elements which got the class myClass directly assigned.
Your want to note it like this:
.myClass h2
Which selects all children of myClass which have the tagname h2
The CSS :first-child selector allows you to target an element that is the first child element within its parent.
element:first-child { style_properties }
table:first-child { style_properties }

Select the first <h3> element after a class definition

I have the following code:
<div class="wrapper">
<div class="location info">
<h3>Location</h3>
<h3>should be no stlye</h3>
</div>
<div class="skills info">
<h3>Skills</h3>
<h3>should be no stlye</h3>
</div>
</div>
I'm trying to style the first h3 element after an info class. I thought this should work, but it dosen't:
.info:first-child {
color: color: rgb(200,50,50);
}
Why isn't this working? How should I style the first element in . info without adding extra markup in the html?
You need a space:
.info :first-child
The first-child pseudo element describes the element itself, not the children of the element. So, without the space you are selecting elements with a class of info that are the first child of their parent.
The space specifies that you are looking for descendants of .info. Since you are looking for just direct children, you should use the child combinator - >, and probably also specify only h3 elements:
.info > h3:first-child
Edit: I only noticed the problem with the selector. As mentioned in other answers (+1 to user1479606), you have a typo in your style definition as well: color: color: ... should be color: ....
You're not far away, try this:
.info > h3:first-child {
color: rgb(200,50,50);
}
But instead of using something like this, I believe the best approach would be to add a meaningful class to the first h3 - this will make reading the CSS and markup much easier in the future and it will prevent unexpected behavior when editing your markup. For example:
.info-title {
/* your styles here */
}
Your css is not correct, you only need to specify color once. You also need to make a more slightly change to your selector:
.info > h3:first-child {
color: rgb(200,50,50);
}
Demo: http://jsfiddle.net/WSZcS/
I'm trying to style the first h3 element after an info class.
.info > h3 {
color: rgb(200,50,50);
}
If your h3 tag is not the first child element you can use
.info > h3:first-of-type {
color: rgb(200,50,50);
}
