Css Universal Selector

CSS Universal Selector is a powerful tool in your styling arsenal, as it allows you to select all elements on a page. It’s denoted by an asterisk *. This means that any style you apply using the universal selector will affect every single element without exception. While it can be useful for resetting styles or applying broad styles, it should be used judiciously since it may affect performance and lead to overridden styles if not carefully managed.

 * {
    margin: 0;
    padding: 0;
    box-sizing: border-box;
  }

In the example above, the universal selector is used to reset margins and paddings for all elements to ensure a consistent layout across the web page. It also sets the box-sizing property to border-box, ensuring that the width and height you set for the elements includes padding and borders. This approach helps in simplifying the CSS styling process.

 * {
    font-family: Arial, sans-serif;
    color: #333;
  }

Another common use case is to set a default font and text color across all elements. This is particularly useful for maintaining visual consistency across your site. However, be careful when using the universal selector to apply styles that might be too broad, as it can lead to unwanted consequences on specific elements that may need distinct styles.

 body {
    background-color: #f4f4f4;
  }

  h1, h2, h3 {
    margin-bottom: 10px;
  }

Therefore, while the universal selector can simplify your CSS by applying a set of styles universally, it’s crucial to balance its usage with more specific selectors to maintain control over individual element styling and ensure optimal performance.

 .btn {
    padding: 10px 15px;
    border: none;
    background-color: #007BFF;
    color: white;
    cursor: pointer;
  }
