ASCII art isn't just decoration - it's a constraint that forces elegant solutions.

Box Drawing Characters

Here are the Unicode box-drawing characters I use:

CharacterNameCode
Double top-leftU+2554
Double top-rightU+2557
Double bottom-leftU+255A
Double bottom-rightU+255D
Double verticalU+2551
Double horizontalU+2550
Double vertical-rightU+2560
Double vertical-leftU+2563

Responsive Design Challenge

The tricky part? Making boxes look good at any width. My solution:

fn create_content_line(content: &str, width: usize) -> String {
    let visual_width = count_visual_width(content);
    let padding = width - visual_width;
    format!("{}{}", content, " ".repeat(padding))
}

Tips

  1. Always use monospace fonts
  2. Account for Unicode character widths (some are double-width!)
  3. Test on multiple browsers - emoji rendering varies wildly
