Seasonal moments are a big opportunity for eCommerce brands to build emotional connection—and boost conversions. But for most teams, updating the entire site’s look and feel to reflect the festive spirit can be a logistical nightmare, requiring design work, dev cycles, and deployment delays.

A gourmet food brand tackled this differently. Instead of redesigning their website for every Diwali, Christmas, or Raksha Bandhan, they used CustomFit.ai’s global CSS update feature to apply festive themes across the entire site instantly.

With just a few lines of CSS, they changed colors, added subtle decorative elements (like snowflakes or diyas), and introduced seasonal typography. It was all managed from one place—no file uploads, no risking broken layouts, and no developer involvement. Best of all, changes were rendered across all pages, on desktop and mobile, flicker-free and fast.

To optimize further, they ran theme-based A/B tests to see which color palette or festive design variation drove higher engagement and sales. During Christmas, for example, one variation with warm reds and greens outperformed the control version with a 30% lift in session duration and a notable increase in product discovery and checkout activity.

This strategy proved that you don’t need a full design overhaul to make your brand feel relevant and celebratory. With CustomFit.ai, seasonal freshness becomes part of your CRO toolkit—quick to launch, measurable in performance, and totally scalable across your catalog.
