I haven't done this course yet, but from the looks of things I assume he's just using CSS borders to highlight things.

I would check out this documentation from w3schools.com on CSS Borders.

looks like to me he didnt use any tool, he did it in a video editor.

Brendon Butler is correct. The video either cuts out the dev tools so you can't see him overriding the styles to apply the borders directly, or the video cut out those parts to speed up the flow.
