As answered by people managing CodePen and MOCKLIO.
MOCKLIO's answer:
We're the only art mockup tool offering 3D video renders with ray-traced lighting. Your art doesn't paste onto a wall – it becomes part of the scene with realistic physics and depth.
MOCKLIO's answer:
Built for Artists, By an Artist: Generic mockup tools are built for everything – logos, app screens, business cards. MOCKLIO is laser-focused on one thing: making art look incredible in real spaces.
Cinema-Quality Video Renders We're the only art mockup tool offering 3D video renders with ray-traced lighting. Your art doesn't paste onto a wall – it becomes part of the scene with realistic physics and depth.
Curated, Not Cluttered Other tools dump 1000+ generic templates on you. MOCKLIO gives you expertly designed rooms (and adds 2 more monthly). Quality over quantity.
MOCKLIO's answer:
✓ Artists selling originals online ✓ Photographers selling prints on Etsy/Shopify ✓ Canvas print shops needing product photos ✓ Galleries showcasing collections ✓ Art students building portfolios ✓ Anyone who knows white backgrounds don't sell art
MOCKLIO's answer:
MOCKLIO was built by Basti – a solo founder with 7 years as a Senior PM, 5 years as an artist, and 4 years as a 3D artist. He watched his own art sit unsold despite being objectively good. The problem? Presentation. Flat photos don't sell art. Context does. MOCKLIO is the tool he needed 5 years ago – and the tool thousands of artists need today.

> I vividly remember IE and many hacks to have css elements properly working in it… The common advice now is to only use CSS that is supported in the last two major versions of each major browser. You can check any css property's support... - Source: Hacker News / about 2 months ago
Thank you, heartfelt... For sharing an artwork, a miracle! Just in case, have you considered publishing the work at platforms as CodePen, where genius Artists/People express their art, too, as you?: // https://codepen.io/. - Source: Hacker News / 3 months ago
Embed on DEV: If you prefer CodePen embed, create a Pen with that HTML and add to the post as: {% codepen https://codepen.io//pen/ %}. - Source: dev.to / 12 months ago
