The techniques we use to produce clean, conceptual, text-free illustrations - shown with one real course rendered five different ways, each next to the exact prompt.
Responsive images shrink one photo to fit every screen. Art direction does something better — it serves a completely different crop to a phone than to a desktop, so your mobile hero fills the screen instead of becoming a thin, unreadable strip. It's a design win and a performance win at once.
A vector graphic is just math, so it stays razor-sharp at any size and weighs a fraction of a photo. That makes SVG the right choice for logos, icons, and diagrams — but only if you embed it the right way, strip the bloat, and sidestep the handful of traps that make a "sharp" format look fuzzy.
