From Figma to a Next.js landing page: what always gets lost in translation

A Figma mockup approved by the client, then a landing page shipped three weeks later that no longer quite matches: the spacing crept tighter, a fallback font flashes for a split second before the real one loads, the "hover" button doesn't respond the way it did in the interactive prototype. Nobody made an obvious mistake — it's the trip itself, from a static image to code running inside a browser, that absorbs part of the original fidelity. This phenomenon has a name in software engineering and interface-design research, and more importantly, concrete levers to limit it on a landing page.

A documented gap, not a team problem

A study by K. J. Kevin Feng, Tony W. Li and Amy X. Zhang, presented in 2023 at CHI — the largest research conference on human-computer interaction — on the collaborative practices of interface designers inside companies (available on Google Scholar), documents what the authors call design-development divergence: the mockup and the shipped product drift apart over the course of a project, because the reasoning behind each visual choice (why this spacing, why this fallback font) doesn't survive the move from the design tool to the code editor. Visual information travels through the mockup; the intent that produced it often gets lost along the way.

This isn't specific to poorly organized teams: the difficulty is general enough to have justified years of machine-learning research into automatically generating code from a single interface image. The foundational work on the topic, pix2code by Tony Beltramelli, presented in 2017 at the ACM SIGCHI EICS conference (available on Google Scholar), trains a neural network to reconstruct an interface's code from a single screenshot, reaching roughly 77% accuracy. That number cuts both ways: high enough to show that an image carries most of a page's visual structure, and far enough from 100% to confirm that part of a design — interaction, intent, keyboard and click behavior — simply doesn't show up in a still image.

What a Figma mockup never shows

• Responsive behavior between breakpoints. Figma renders one state per screen width (mobile, tablet, desktop); it doesn't show how a headline reflows at 850 pixels wide, between the two drawn frames — the developer decides, usually without a written spec.
• Real interaction states. A hover, a keyboard focus, an "in-progress" form-submission state sometimes exist in a Figma prototype, but rarely for every single component; keyboard accessibility in particular gets coded from scratch most of the time.
• Font and image loading. A mockup shows the final font instantly; a browser downloads the font before rendering it, with a flash-of-unstyled-text swap that Figma can't represent — a detail that directly affects the LCP measured in production.
• Real content, longer or shorter than the placeholder text. A 4-character client name in the mockup can turn into 22 characters in production, and break a layout that was never tested with real text.

Where the gap costs the most on a landing page

On a typical brochure site, a slight fidelity drift often goes unnoticed. On a landing page, whose entire job is converting a visitor within seconds, every gap touches something that matters: tighter spacing near the call-to-action button changes its perceived clickable area; a fallback font that lingers too long delays the moment a visitor can read the value proposition; an uncoded hover state makes a secondary button effectively invisible on desktop. None of this shows up re-reading the mockup — only testing the real page, in a real browser, with real content.

Closing the gap: what actually works

• Start from a shared token system, not eyeballed values. Mapping the mockup's colors, spacing and sizes to a fixed scale (Tailwind's, for instance) rather than transcribing approximate pixel values eliminates most spacing drift — which is exactly what an already-coded template, with its tokens already set, saves you from redoing on every project.
• Document the missing states before coding. List, component by component (button, form field, testimonial card), the states the mockup doesn't show — hover, focus, loading, error — and settle them before the first line of CSS, rather than improvising them on the keyboard mid-build.
• Preload the final font. Using Next.js's built-in font loading (next/font) instead of a link to an external CDN removes the visible swap between fallback and final font, and improves first-render time along the way.
• Test with real content, not the demo copy. Paste the final text — product name, full testimonial, price — into the coded page before final sign-off; that's where unexpected overflow and line breaks show up, never in the mockup.

Why starting from an already-coded template changes the equation

The research on this converges on one point: the gap between design and code isn't solved by drawing a more detailed mockup, but by shrinking the distance between the two steps. An already-integrated React/Next.js template — like the ten models in the LanderKit catalog — removes part of the trip itself: the palette, typography and spacing are already coherent Tailwind tokens, hover and focus states are already coded, and what you see matches the final render from the first page opened in a browser, with no intermediate translation step. For an agency or freelancer who still needs to deliver a bespoke identity to a client, the Local Agency template can be customized directly in the code — logo, colors, copy — without starting from a Figma mockup at all.

That doesn't remove the need to verify the result once it's live: our technical launch checklist covers what to check before publishing, and our guide on deploying a Next.js landing page on Vercel details the steps once the code is ready.

When a Figma mockup is still worth it

Going straight to code isn't a universal answer either. A mockup is still essential to validate an entirely new brand identity with a client before committing development time, to get sign-off from several stakeholders who don't read code, or to explore several visual directions quickly. The right question isn't "Figma or code," but when to switch from one to the other: as early as possible for anything touching structure, real layout and interactions, and Figma upstream only for what still needs deciding — palette, tone, brand calls.
