Solve Render-Blocking for Faster Above-the-Fold Loads

CSSPro for PrestaShop uses today’s best practices—no magic tricks or voodoo—to solve one of the hardest challenges in eCommerce: eliminating CSS blocking to improve above-the-fold page rendering and real visitor experience.

The Solution: Smart Preloads, Stylesheet Management & Stealth Testing

CSSPro targets these issues with two core features, plus safe testing:

Asset Discovery Dashboard:
You can initiate CSS discovery simply by visiting the front office. CSSPro records every CSS file registered as your PrestaShop page is being prepared for render and displays them in a simple dashboard—where you can also manage how each stylesheet is loaded.

Critical CSS Preloads:
By default, CSSPro injects preload tags for all CSS files directly into your site’s header. While advanced configuration options are available, this automatic preloading alone solves the core render-blocking problem and accelerates above-the-fold rendering.

A/B Testing | Stealth Mode:
When you install and configure CSSPro, it enters stealth mode by default. Only your IP address (or additional IPs you specify) will see CSS discovery and loading changes, allowing for private review and A/B testing before launch. Add team or group IPs for broader testing. When you’re satisfied with the improvements, simply disable stealth mode to go live for all visitors.

Why It Matters

1. Faster above-the-fold content: Visitors see key content almost instantly, reducing wait time and frustration.
2. Better first impressions: Quick rendering makes your store feel modern and professional.
3. Higher engagement and sales: Shoppers are more likely to stay and complete purchases when pages load smoothly.
