Explanation:

  • This HTML document demonstrates how to set different styles for the left border of h1 elements using CSS classes.
  • Each h1 element has a common style with a solid border and a width of 3 pixels.
  • Additional CSS classes are defined to specify different styles for the left border:
    • none: No left border
    • dotted: Dotted left border
    • dashed: Dashed left border
    • solid: Solid left border
    • double: Double left border
    • groove: Groove left border
    • ridge: Ridge left border
    • inset: Inset left border
    • outset: Outset left border
  • Each h1 element is assigned one of these classes to apply the corresponding left border style.
