  • The CSS code sets the style for the <h1> elements to have a solid border with a width of 10 pixels.
  • A class named "outset" is defined for <h1> elements that specifies an outset style for the left border.
  • In the HTML body, there is a paragraph with the text "w3resource Tutorial" followed by an <h1> element with the class "outset", resulting in an outset-style left border for that element.
  • There's also a paragraph explaining that the effect of the outset border depends on the border-color .
