CSS Nested Classes

Summary: In CSS, nested classes are used to create a style for one or more child elements. You can nest CSS as deeply as you want and the CSS will only apply to those that it is assigned to. In this blog post, we’ll take a look at how nesting CSS classes work and some ways in which they can be applied to create complex sections on your website.

What is the meaning of class in css?

A CSS class is a style that can be applied to HTML elements. These are broken into different sections and when you want to apply a particular style, you include it on your HTML element with the class attribute.


.class-Name{cssproperties: value;}

The meanings of the various classes include:

.hugeBox { width: 100%; }
.hugeBox-top { margin-top: 10px; }
.hugeBox-bottom { margin-bottom: 10px; }
.hugeBox-right { margin-right: 10px; }
.hugeBox-left { margin-left: 10px; }

What are CSS nested classes?

Nested CSS classes can only be applied to child elements. You might have an outer CSS rule that looks like .parent-class { color: blue; } and then you would nest the CSS for children of this parent inside it like so: /*nested CSS rules go here*/

.parent-class .child-class { background: rgb(255,0,255); }

Why use nested CSS classes?

Nested CSS classes can be used to apply styles for multiple levels of children with just a few lines of code and they help keep your CSS clean and organized. This is especially useful when you have complex sections on your website that require different styles for the same type of child.

Where to use nested CSS classes?

Nested CSS can be used in any place where you would apply class-based styling, but it is most often seen with HTML elements and sections of a page like headers or footers. When nesting CSS, it’s important to use the same class names for all of your nested CSS rules.

Nested CSS classes are a great way to style complex sections on your website, like headers and footers that require specific styles for different child elements. They can also help keep CSS clean and organized when you need to apply styling for multiple levels of children with just a few lines of code.

Group Selector: If you want to apply the same properties to many selectors, then simply separate them with commas in one line. This way makes it easier for readability and debugging purposes.

You can simplify your code by separating out your selection property declarations into their own lines of text rather than listing all those on just a single row because this will make it more readable; furthermore, if something goes wrong when testing or previewing what has been coded up so far during development, debuggers are likely able to pinpoint which selector is causing an issue much quicker as opposed having difficulty parsing through long lines that contain multiple declaration statements (setting ids/classes).


.classA, .classB {}


div, .classA, .classB {
    color: red;

Nesting: CSS is a language that can be used to style the way your HTML looks, and with it, many different selectors are made possible. If well structured there shouldn’t need for more than class or ID styles as they specify properties within other classes themselves; however if not then you might have trouble getting everything done without creating an overly complex set of rules which will take up loads of space in files from having too much information inside them.


.classA .classB {}


div .classA, div .classB {
    color: red;

Explanation: In the above code, .classA is the parent CSS class and it contains a child CSS class called .classB. In this case, div is both a descendant of .classA as well as an instance of its own CSS selector – which makes sense given that there are two levels to this relationship.

What happens if you don’t use nested CSS?

If you don’t use CSS nested classes, then the styling of a particular element will be inherited from its parent and it would then override any other styles that are applied to it. For example, if an ID had been assigned to div with many properties set for display or position values but they were not specified in .classA; then the ID would be overruled by any styles that are applied to div in .classA.


In this blog post, we’ve shared some of the secrets to styling complex sections with CSS nested classes. This technique will allow you to style multiple components in a section without having to repeat any styles and give your site more consistency across pages.
