Introduction
CSS (Cascading Style Sheets) is a fundamental language used in web development to control the presentation and layout of web pages. One of the key features of CSS is its powerful selectors, which allow developers to target specific elements within an HTML document and apply styles accordingly. In this blog, we will explore the world of CSS selectors, from the basics to more advanced techniques, empowering you to create visually stunning and responsive web designs
Understanding the Basics
CSS selectors are patterns used to select and style HTML elements. They consist of three main components:
Element Selector
The most basic type of selector, which targets elements based on their tag names. For example, to style all paragraph elements, you would use the selector p.
Example
Here, all <p> elements on the page will be red text color.
p { color:red; }
Class Selector
Targets elements with a specific class attribute. Class selectors are prefixed with a dot (.). For instance, if you want to style all elements with the class "highlight," you would use the selector .center.
Example
In this example, all HTML elements with class="center" will be red and center-aligned:
.center { text-align: center; color: red; }
ID Selector
Targets a single element with a specific ID attribute. ID selectors are prefixed with a hash (#). For example, to style an element with the ID "#para1," you would use the selector #para1.
Example
The CSS rule below will be applied to the HTML element with id="para1":
#para1 { text-align: center; color: red; }
The CSS Universal Selector
The universal selector (*) selects all HTML elements on the page.
Example
The CSS rule below will affect every HTML element on the page:
* { text-align: center; color: blue; }
What are pseudo-classes?
A pseudo-class is used to define a special state of an element.
for example, it can be used it:
Style an element when a user mouses over it
Style visited and unvisited links differently
Style an element when it gets focus
Syntax
selectors:pseudo-class{
property: value;
}
