CSS Selectors

    CSS (Cascading Style Sheets) is a style sheet language used to describe the presentation of a document written in HTML or XML. CSS Selectors are a powerful tool used to target specific HTML elements and apply styles to them. In this blog, we will explore CSS Selectors and how they can be used to style HTML elements.

Types of CSS Selectors

    There are several types of CSS selectors that can be used to target specific HTML elements. Here are some of the most common types of CSS selectors:

Element Selector :- Targets all instances of a specific HTML element. For example, the following code targets all <p> elements:

p {

      color: blue;

}

Class Selector :- Targets all instances of an HTML element with a specific class attribute. For example, the following code targets all elements with class "highlight":

.highlight {

      background-color: yellow;

}

ID Selector :- Targets a specific HTML element with a specific ID attribute. ID's are unique and can only be used once per HTML document. For example, the following code targets the element with ID "header":

#header {

      font-size: 24px;

}

Descendant Selector :- Targets an HTML element that is a descendant of another HTML element. For example, the following code targets all <a> elements that are descendants of <li> elements:

li a {

      text-decoration: none;

}
