CSS Universal Selector

The Universal Selector in CSS is your one-size-fits-all tool. It lets you apply styles to every single element on your webpage—no exceptions. Think of it as casting a net over the entire page to make everything uniform or to reset styles!

1. How to Use the Universal Selector

Using the Universal Selector is as simple as using an asterisk (*). Place it in your CSS file and define your styles:

/* Apply styles to all elements */
* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

This is especially useful for resetting styles across the webpage.

2. Examples of Universal Selector in Action

Here are some scenarios where the Universal Selector is incredibly handy:

/* Example: Add a border to every element */
* {
  border: 1px solid #ccc;
}

In this example, every element gets a light gray border, which can help visualize element boundaries during development.

/* Example: Change font size and color for all elements */
* {
  font-size: 16px;
  color: #333;
}

3. Things to Keep in Mind

While the Universal Selector is powerful, be cautious. It can be heavy-handed, especially on larger projects, as it affects every element and might override other specific styles. Use it wisely!
