Explanation:

This HTML document demonstrates how to animate the border-left-color property of an element.
The div with the ID "mydiv" is styled with a width of 300 pixels, a height of 200 pixels, and a border of 15 pixels solid with the color #CC63FF.
An animation named "mymove" is defined using keyframes. It animates the border-left-color property to change to the color #FF63CC at 50% of the animation duration.
The animation is applied to the div element, making the left border color transition smoothly between the specified colors.
