Defining CSS Where Pseudo Class:

CSS where pseudo class is a powerful tool that allows you to apply styles to elements based on their position within the document tree. It's like having a superpower that lets you target specific elements with precision, making them stand out or blend in as you desire.

Using 'where' Pseudo Class:

To use the 'where' pseudo class, you simply need to add ':where()' to the selector you want to target. Inside the parentheses, you specify the condition that the element must meet in order for the styles to be applied.

Here's an example to illustrate:

div:where(.special) {
  color: red;
}

In this example, we're targeting all 'div' elements that have a class of 'special.' The 'color' property is then set to 'red,' which will make the text inside these elements appear in red.

The CSS where pseudo class offers several key benefits:

• Improved Selectivity: It allows you to target elements with greater precision, making your CSS code more efficient and maintainable.
