How to use dark mode templates with ChatGPT Codex
Pick a design
Choose a dark mode design above and open it to see it live.
Copy the template

Set up ChatGPT Codex

Prompt, then refine
Paste it and describe your product. Then follow up with: "Implement this section to match design/template.html exactly. Do not introduce new colours or fonts."
What makes a good dark mode section
Common types: dark landing pages, dark dashboards, dark heroes over a glow and full dark product sites.
Near-black, not pure black
Dark grey backgrounds with lighter layers create depth.
Readable contrast
Body text stays light enough to read comfortably.
One accent colour
Colour is used sparingly so it means something.
Common mistake: Grey text on near-black that is too dim to read. Dark mode website design ideas →
