Explain the purpose of using the CSS box-sizing Property

In CSS, targeting only the first child of an element is useful for applying styles exclusively to the first child element within a container. The :first-child pseudo-class is used to select and style the first child element.

Syntax

/* Selecting and styling the first <p> element within a container */
  .container p:first-child {
  font-weight: bold;
}

/* Selecting and styling the first child of any type within a container */
  .container :first-child {
  color: red;
}

Features

• :first-child Pseudo-class: Targets the first child element of its parent.
• Specific Element Type: It can be used to select the first child of a specific type within a container.
• Universal Selector: It can also be applied using the universal selector (*) to select the first child regardless of its type.
