I published a one-page site by embedding a Google Slides deck. It's jumpy on the desktop and mobile. The content jitters and the smooth scrolling is simply not working. Here’s the setup: the entire page is essentially a Google Slides iframe sitting inside standard HTML/CSS. I need someone who understands iOS WebKit quirks, overflow handling, and hardware-accelerated scrolling to diagnose what’s blocking smooth scroll and apply a clean fix. Whether that means tweaking the existing embed, adding the right CSS/JavaScript, or rebuilding the deck in lightweight HTML while keeping the exact visuals, I’m open to the most efficient route. Deliverables • Identify the root cause. • Supply the corrected code or snippet (CSS/JS/HTML) I can drop straight in • Provide a quick before-and-after demo link or video so I can test on my iPhone • Short, clear summary of what changed for future maintenance If you’ve solved similar scrolling issues in WebKit and can turn this around quickly, I’m ready to get started right away.

I can diagnose the WebKit scrolling issue, identify what’s causing the jitter in the Google Slides iframe, and apply a clean, mobile-safe fix—or rebuild it in lightweight HTML if that’s the best solution. You’ll get drop-in code plus a clear before/after demo to verify smooth scrolling on iOS. — Muzammil

Hi there! I understand how frustrating it can be when a simple Google Slides embed causes jumpy scrolling on both desktop and mobile. It breaks user experience and makes your presentation hard to follow, especially on iOS devices where WebKit quirks can block smooth scrolling. I have experience fixing smooth scroll issues with iframes and embedded content, handling overflow, hardware acceleration, and iOS-specific quirks. I’ve worked on similar projects where Google Slides, PDFs, or other iframe content caused jittering, and delivered clean, efficient fixes using HTML, CSS, and minimal JavaScript—sometimes even rebuilding the content in lightweight HTML for perfect smoothness. My approach will first identify the exact cause of the jitter, then implement a solution that works across all devices. You’ll get corrected code ready to drop in, a quick demo for iPhone testing, and a short maintenance summary so you or your team can manage it later. Check our work https://www.freelancer.com/u/ayesha86664 Do you want me to try a fix within the current embed first, or rebuild the deck in HTML for maximum smoothness? Let me know if you’re interested & we can discuss it. Best Regards, Ayesha

I've diagnosed and fixed this exact WebKit iframe scrolling issue multiple times—the jitter you're seeing is almost certainly caused by the Google Slides embed fighting with iOS Safari's scroll handling, typically due to missing `-webkit-overflow-scrolling: touch`, improper iframe containment, or the embed triggering layout recalculations during scroll. My approach: first I'll inspect your current embed structure to pinpoint whether it's an overflow context issue, missing hardware acceleration (`transform: translateZ(0)`), or the iframe's internal scroll conflicting with the page—then I'll provide a drop-in CSS/JS fix or, if cleaner, rebuild the deck content in lightweight HTML that preserves your exact visuals. I can start immediately and will deliver the root cause analysis, corrected code, and a before/after demo for iPhone testing.
