Explain `state: link`.

In CSS, state: link refers to the default state of an anchor (<a>) element that has not yet been visited by the user. It is defined using the :link pseudo-class.

Here's how it works:

• Default Appearance: The styles applied to links in their unvisited state can be customized using the a:link selector. For example, you can set the color, text decoration, background color, and other properties.

Example:

a:link {
    color: blue; /* Default link color */
    text-decoration: none; /* No underline */
    font-weight: bold; /* Bold text */
    padding: 5px; /* Padding around the link */
    background-color: #f0f0f0; /* Background color */
    border-radius: 3px; /* Rounded corners */
    transition: all 0.3s ease; /* Smooth transition for state changes */
}

In this example, any unvisited link will appear blue, bold, and have a light gray background with rounded corners. The transition property allows for smooth changes when the link state changes (e.g., when hovered or clicked).
