Introduction

Using & with pseudo-classes helps you write cleaner styles that change when elements are hovered, focused, or active.

You want a button to change color when someone moves their mouse over it.
You want a link to look different when it is clicked or focused by keyboard.
You want to style a form input differently when it is active or disabled.
Syntax
SASS
&:pseudo-class { property: value; }

The & symbol means 'this selector' in Sass.

Pseudo-classes like :hover or :focus describe special states of elements.

Examples
This changes the button text color to red when hovered.
SASS
button {
  color: blue;
  &:hover {
    color: red;
  }
}
This adds an orange outline when the link is focused (like when tabbing with keyboard).
SASS
a {
  text-decoration: none;
  &:focus {
    outline: 2px solid orange;
  }
}
This styles disabled inputs with a light gray background.
SASS
input {
  border: 1px solid gray;
  &:disabled {
    background-color: lightgray;
  }
}
Sample Program

This example shows a blue button that gets darker when hovered and shows a bright outline when focused (like when using keyboard navigation).

    }
    button:focus {

      outline-offset: 2px;
    }

Important Notes

Always use & inside a selector block to refer to the current selector.

Pseudo-classes help improve user experience by showing interactive states.

Test your styles with keyboard navigation to ensure accessibility.

Summary

Use & with pseudo-classes to style element states like hover and focus.

This keeps your Sass code organized and easy to read.

It helps make your website interactive and accessible.
