এরপর থেকে আমরা Bangla-English mix এ এগোবো—যেমনটা BD users daily life-এ use করে।

Dark Mode কেন? 

  • Eye Comfort & Accessibility: Low-light এ glare কমে; high contrast text (WCAG-friendly) পড়তে easy।

  • Battery & Performance: OLED displays-এ true black backgrounds save power; lighter assets = faster load.

  • Brand Differentiation: Modern, premium aesthetic—especially tech, finance, media niches।

  • Focus on Content: Dark canvas-এ CTA, images, graphs more “pop”—higher attention & CTR।

  • Night-time Users: Bangladesh-এ late-night browsing খুব common—dark mode improves session length & retention।

Result: stable, compounding SEO gains—especially for content-heavy sites (news, blogs, documentation, portfolios).

  4. Asset Pass: logos, icons, banners—add dark variants
