HTML to Figma Glossary — Design-Development Terms Defined

#

Accessibility

Accessibility (a11y) is the practice of building web content that can be used by people with disabilities — including those using screen readers, keyboard navigation, or assistive technologies. In Figma workflows, accessibility means ensuring imported layers carry semantic meaning, sufficient color contrast, and correct reading order. When using HTML to Figma, starting with well-structured HTML that uses semantic elements produces a more accessible Figma layer hierarchy.

#

Auto Layout

Auto Layout is Figma's constraint-based layout system that mirrors CSS Flexbox — it allows frames to resize automatically as their contents change. When HTML to Figma imports HTML, it reads computed Flexbox positions and recreates them as accurately positioned frames. Designers can then apply Auto Layout to those imported frames to produce fully resizable, responsive Figma components.

#

Color Palette

A color palette is the curated set of colors — primary, secondary, neutral, and semantic (success, warning, error) — defined in a design system. Color palettes are typically encoded as design tokens and applied consistently across both code (CSS custom properties or Tailwind config) and Figma (local styles or variables). Keeping color palettes synchronized between code and Figma is one of the main benefits of a design system migration.

#

Component Library

A component library is a shared repository of reusable UI components — buttons, inputs, cards, modals — that teams build once and consume across products. In Figma, this lives as a shared library; in code, it may be an npm package, Storybook, or a monorepo package. HTML to Figma is commonly used to sync a coded component library back into Figma when design files fall behind the implementation.

#

Computed Styles

Computed styles are the final, resolved CSS property values a browser assigns to a DOM element after applying the cascade, inheritance, and layout algorithms. Unlike authored styles (which may use relative units or shorthand), computed styles are absolute — pixel dimensions, resolved colors, and exact font sizes. HTML to Figma reads computed styles directly from the browser's rendering engine to produce pixel-accurate Figma layers.

#

Core Web Vitals

Core Web Vitals are Google's set of real-world performance metrics that measure user experience quality: Largest Contentful Paint (LCP, loading speed), Interaction to Next Paint (INP, interactivity), and Cumulative Layout Shift (CLS, visual stability). Strong Core Web Vitals scores are a confirmed Google Search ranking signal and directly affect organic search visibility. See how code-based imports compare to screenshot tools in terms of performance impact.

#

CSS Flexbox

CSS Flexbox (Flexible Box Layout) is a one-dimensional layout model that distributes space along a single axis — row or column — and aligns items within a container. It is the most common layout system for web UI components. HTML to Figma translates Flexbox computed positions into accurately placed Figma frames that visually reproduce the browser layout, and is compatible with Tailwind's flex utilities.

#

CSS Grid

CSS Grid Layout is a two-dimensional layout system that positions elements into rows and columns simultaneously. Unlike Flexbox, Grid excels at macro page layouts — sidebars, multi-column cards, and dashboard grids. HTML to Figma captures the computed pixel positions of Grid children as accurately placed Figma frames, preserving the visual layout. Works with Tailwind CSS Grid classes like grid-cols-3.

#

Design Handoff

Design handoff is the process of transferring finalized design specifications from designers to developers so they can build the UI accurately. Traditionally this means annotated Figma files with measurements, tokens, and interaction notes. HTML to Figma enables reverse handoff — taking a coded implementation and regenerating a Figma file that matches what was actually built, which is useful when code diverges from the original design.

#

Design System

A design system is a collection of reusable components, design tokens, patterns, and guidelines that govern the visual language of a product. It lives in both code and Figma. Keeping code and Figma in sync is one of the primary use cases for HTML to Figma, especially after a design system migration.

#

Design Tokens

Design tokens are the atomic values of a design system — colors, typography sizes, spacing steps, border radii, and shadow definitions — stored in a format that both design tools and code can consume. Tokens are defined in JSON or YAML and compiled into CSS custom properties, Tailwind config, or Figma variables. They are the single source of truth that prevents visual drift. Learn how tokens relate to design system migrations.

#

E-E-A-T

E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness — the quality signals Google's Search Quality Raters use to evaluate content. Experience reflects first-hand knowledge; Expertise reflects subject-matter depth; Authoritativeness measures how recognized a source is in its domain; Trustworthiness covers accuracy and transparency. Strong E-E-A-T is essential for YMYL content and is a major factor in how AI overviews and generative search engines select cited sources. See also: GEO.

#

Figma Plugin

A Figma plugin is a program that extends Figma's functionality using the Figma Plugin API — it can create, read, and modify nodes in the Figma document, access the file system, and communicate with external services. HTML to Figma is a Figma plugin: it reads HTML and CSS input, uses the Plugin API to create native frames, text nodes, rectangles, and vector paths, and places them directly in the open Figma document. Learn how to use it.

#

GEO (Generative Engine Optimization)

Generative Engine Optimization (GEO) is the practice of structuring web content so it is discovered and cited by AI-powered search engines and assistants — including ChatGPT, Perplexity, Google AI Overviews, Microsoft Copilot, and Claude. GEO strategies include structured data markup (JSON-LD), clear entity definitions, authoritative sourcing, direct answer formatting, and content that is machine-readable and factually verifiable. See also: E-E-A-T.

#

JSON-LD

JSON-LD (JavaScript Object Notation for Linked Data) is a W3C standard for embedding structured semantic data in web pages using a <script type="application/ld+json"> tag. Search engines and AI systems use JSON-LD to understand entity relationships, page type, and factual claims. JSON-LD schemas such as FAQPage, HowTo, and DefinedTermSet are key components of both SEO and GEO strategies. When implemented correctly, JSON-LD can unlock rich results in search engine result pages.

#

Layer Tree

The layer tree is Figma's hierarchical panel that shows every object in a document as a nested node structure — frames contain groups, groups contain shapes and text, and so on. When HTML to Figma converts an HTML document, it maps the DOM hierarchy to an equivalent Figma layer tree: block elements become frames, inline text becomes text nodes, and background images become image fills on rectangle layers. Meaningful layer names are preserved where possible.

#

Pixel-Perfect

Pixel-perfect describes a design or implementation where every element matches the original specification to the exact pixel — no rounding errors, unintended gaps, or misaligned borders. In HTML-to-Figma workflows, pixel-perfect conversion means the imported Figma layers reproduce the browser's visual rendering exactly, using computed styles rather than estimated measurements. This distinguishes HTML to Figma from screenshot-based tools, which flatten designs into non-editable raster images.

#

Responsive Design

Responsive design is a web development approach where layouts and content adapt fluidly to different screen sizes and viewport widths using CSS techniques such as media queries, Flexbox, and Grid. When importing a responsive website into Figma, the plugin captures the computed layout at the current browser viewport width, producing a Figma frame that represents that specific breakpoint. Resize the browser before capturing to import different breakpoints.

#

Rich Results

Rich results (formerly rich snippets) are enhanced search engine result page (SERP) entries that display additional information — star ratings, FAQ dropdowns, How-To steps, event dates, or product prices — pulled from structured data markup. Pages with JSON-LD schemas such as FAQPage, HowTo, Product, and Recipe can qualify for rich results, which typically increase click-through rates significantly compared to standard blue-link search results.

#

Semantic HTML

Semantic HTML is the practice of using HTML elements that convey meaning about the content they contain — <article>, <nav>, <header>, <main>, <aside>, <section> — rather than generic <div> elements. Semantic HTML improves accessibility, helps search engines understand page structure, and makes documents more machine-readable for AI and assistive technology. When used as input for HTML to Figma, semantic markup produces a cleaner, more meaningful layer tree.

#

Spacing System

A spacing system is a set of predefined margin and padding values — typically a numeric scale such as 4px, 8px, 16px, 24px, 32px, 48px, 64px — that design teams apply consistently across all UI components. Spacing tokens in code map to spacing variables in Figma, ensuring that imported layouts and hand-designed components share the same visual rhythm. See how design system migrations handle spacing token synchronization. Related: Design Tokens.

#

Structured Data

Structured data is machine-readable information embedded in a web page that describes its content in a standardized vocabulary — most commonly Schema.org implemented via JSON-LD. Structured data enables search engines and AI assistants to parse facts, entities, and relationships without visual interpretation. Common structured data types include FAQPage, HowTo, Product, Article, BreadcrumbList, and DefinedTermSet. Properly implemented structured data can unlock rich results and improves GEO citation likelihood.

#

Typography Scale

A typography scale is a defined set of font sizes and line heights — such as xs (12px), sm (14px), base (16px), lg (18px), xl (20px), 2xl (24px) — that create visual hierarchy across a UI. Typography scales are encoded as design tokens in code and as text styles in Figma. HTML to Figma preserves the full typography stack — family, weight, size, line-height, and letter-spacing — when importing HTML elements into Figma, ensuring the scale is faithfully reproduced.

#

Vector Path

A vector path is a scalable graphic defined by mathematical curves and anchor points rather than pixel grids, making it resolution-independent at any size. In Figma, SVG elements from HTML are imported by HTML to Figma as native vector paths — fully editable curves that remain sharp at any zoom level. This contrasts with rasterized images, which pixelate when scaled beyond their native resolution. See also: screenshot vs. code import.

#

Viewport

The viewport is the visible area of a web page within a browser window — its width and height determine which CSS media queries are active and how layout algorithms compute element sizes. When using HTML to Figma, the viewport width at the time of HTML capture determines which breakpoint is imported into Figma. To import a mobile layout, resize the browser to a mobile viewport (e.g., 375px wide) before copying the rendered HTML. Related: Responsive Design.
