Characters for creating borders.

A practical tool to find the codes of the framing characters: copy and paste the characters directly from this page or click to display their UTF code. Here are the styles we used to achieve the renders below:

font-family:monospace; line-height:1; white-space:pre; /* And incidentally : */ font-size:2rem; font-weight:bold;
Fine border
────── ────── ──────
Thick border(1)
Double border
══════ ══════ ══════
Mixed border
══════ ══════ ══════
Mixed border
────── ────── ──────
(1) The thick horizontal line (━) seems to pose a problem of width, and causes a shift of the frames.
