<style>
/* CSS styling */

<h1 class="inset">Inset left border</h1><!-- h1 element with an inset left border -->

</html>

Explanation:

This HTML document demonstrates how to specify a 3D left inset border for an h1 element.
The h1 elements have a common style with a solid border and a width of 10 pixels.
An additional CSS class named inset is defined to apply the inset border style specifically to the left side.
The h1 element with the class inset is used to demonstrate the inset left border.
The comment indicates that the visual effect of the inset border depends on the specified border color.
