    Understanding Pseudo-Elements in CSS

    A pseudo-element in CSS allows you to style specific parts of an element without needing to add extra HTML markup. Common pseudo-elements include `::before`, `::after`, `::first-letter`, and `::first-line`.

    Key Points
    • Pseudo-elements let you style subparts of elements or insert content dynamically.
    • They are indicated by a double colon `::` to distinguish them from pseudo-classes.
    • They do not exist in the DOM; they are virtual elements created for styling purposes.
    • Common use cases include decorative content, highlighting the first letter, or adding icons before/after text.
    Example: Using ::before and ::first-letter

    In this example, `::first-letter` enlarges and colors the first letter, while `::before` inserts a star before the paragraph text without modifying the HTML.

    Best Practices
    • Use pseudo-elements to add stylistic content without cluttering HTML.
    • Combine with CSS properties like `content`, `color`, `font-size`, and `background`.
    • Avoid using them for interactive elements that require JavaScript functionality.
    • Test across browsers to ensure consistent rendering.
