Knowing how to use Tabnine for landing page code snippets starts with understanding what Tabnine is: an AI coding assistant that lives in your editor. It completes code as you type and offers a chat panel for questions and generation. So your "prompts" are either comments that steer inline completions or messages in the chat. This guide shows you how to write both for landing page work (hero sections, forms, pricing tables, FAQs), with twelve copy-ready prompts and a review routine, because generated code must always be read, tested and secured before it ships.
How Tabnine works for landing page code
Tabnine integrates with popular editors and IDEs, suggesting completions and answering chat questions about your code. Its supported editors, models, deployment options, privacy settings and pricing change over time, so check the tool's current features and licence terms, particularly if you work with private or client code.
Practical consequences for landing pages:
- Completions follow context. Open files, naming and nearby code shape suggestions. A clear comment above an empty function or component helps a lot.
- Chat follows instructions. Specify stack, constraints and output format.
- It does not see your design. Describe layout, breakpoints and states in words.
The code prompt formula
[Stack and versions] + [component or snippet] + [layout and responsive rules] + [accessibility requirements] + [style approach] + [constraints and things to avoid] + [expected output format]
| Part | Example | |—|—| | Stack | plain HTML5 and CSS, no frameworks | | Component | hero with headline, subhead, CTA button | | Responsive | stack on screens under 640px | | Accessibility | semantic headings, visible focus, 4.5:1 contrast | | Output | one HTML file with a style block, no external libraries |
Basic prompt vs improved prompt
Basic comment in your editor:
// make a hero sectionImproved chat message:
Fill in the blanks below, or click a highlighted word in the prompt.
Write a responsive hero section for a landing page using semantic HTML5 and modern CSS (flexbox and CSS variables, no frameworks, no JavaScript). Content slots: h1 "[HEADLINE]", a one-sentence subheading, a primary link-styled button "[CTA TEXT]" pointing to "#signup", and a decorative image placeholder with empty alt text. Layout: two columns above 768px, single column below with the image after the text. Accessibility: one h1, visible focus outline, minimum 4.5:1 text contrast, button hit area at least 44px. Do not use inline styles or external fonts. Output the HTML and CSS in two separate code blocks with brief comments.Why it works: the stack, layout, accessibility and exclusions leave little room for guesswork.
Page structure snippets
1. Semantic page skeleton
Fill in the blanks below, or click a highlighted word in the prompt.
Create a semantic HTML5 skeleton for a landing page with header (logo text and nav with 3 anchor links), main (hero, features, pricing, FAQ, final CTA) and footer. Use landmark elements, a skip-to-content link, descriptive section headings in order (h1 once, then h2), and a lang attribute. No CSS, no scripts. Add short comments marking where [CONTENT] goes.2. Responsive feature grid
Fill in the blanks below, or click a highlighted word in the prompt.
Write CSS Grid and HTML for a features section with [NUMBER] cards, each containing an icon placeholder (inline SVG slot), an h3 and a two-line description. Layout: 3 columns above 1024px, 2 columns from 640 to 1023px, 1 column below. Use CSS custom properties for spacing and colours, no frameworks. Cards should be a list (ul/li) for screen readers. Include reduced-motion-safe hover styles.3. Pricing table
Fill in the blanks below, or click a highlighted word in the prompt.
Generate an accessible pricing section with [NUMBER] plan cards using plain HTML and CSS. Each card: plan name (h3), price placeholder, list of features, button. Highlight one plan with a "Recommended" label that is not colour-only. Stack cards on mobile. Use placeholders like [PRICE] only, do not invent prices or features. Keep markup clean and class names in BEM style.Forms and interaction snippets
4. Email signup form
Fill in the blanks below, or click a highlighted word in the prompt.
Write an accessible email signup form in HTML with a label linked to the input, type="email", required attribute, helper text and an error message area using aria-describedby and aria-live="polite". Add minimal vanilla JavaScript for client-side validation with clear messages, and note that server-side validation and spam protection are still required. No third-party libraries. Include the form action as [ENDPOINT PLACEHOLDER].Remember: front-end validation is a convenience, not security. Validate and sanitise on the server.
5. FAQ accordion
Fill in the blanks below, or click a highlighted word in the prompt.
Build an FAQ accordion with [NUMBER] items using the native details and summary elements, styled with CSS, keyboard accessible by default, with a visible focus state and a rotating chevron that respects prefers-reduced-motion. Provide the HTML and CSS, then suggest optional JavaScript only if truly needed, and explain why it may not be.6. Sticky header with mobile menu
Write HTML, CSS and a short vanilla JS script for a sticky header with a mobile menu toggle. Requirements: button with aria-expanded and aria-controls, menu closes on Escape and on link click, focus returns to the toggle button, works without JS as a visible link list on desktop. Keep code under 80 lines of JS and avoid libraries.Framework-specific prompts
7. React component
Fill in the blanks below, or click a highlighted word in the prompt.
Write a React function component for a testimonial section using TypeScript. Props: array of { quote: string; name: string; role: string }. Render a semantic figure/blockquote/figcaption structure, a responsive CSS Module for 1, 2 and 3 columns, and handle an empty array gracefully. No external libraries. Include a short usage example and a simple unit test with [TEST LIBRARY].8. Tailwind variant
Create a landing page call-to-action banner using Tailwind CSS utility classes only. Include heading, supporting text and button, centred, with responsive padding, dark-mode support using the dark: variant, and focus-visible ring styles. Do not use arbitrary values unless necessary. Provide the HTML only and list the Tailwind features assumed.Performance, SEO and security prompts
9. Performance review
Fill in the blanks below, or click a highlighted word in the prompt.
Review the following landing page HTML and CSS for performance problems: render-blocking resources, missing width and height on images, oversized images, unused CSS, layout shift risks. List each issue with the line, why it matters and a fix. Do not rewrite everything.
[PASTE CODE]10. SEO and metadata snippet
Fill in the blanks below, or click a highlighted word in the prompt.
Write the head section for a landing page: title and meta description placeholders ([TITLE], [DESCRIPTION]), canonical link, viewport meta, Open Graph and Twitter card tags, and a JSON-LD block for [PAGE TYPE] using only the properties I specify: [LIST]. Do not invent data. Add comments explaining what to replace.11. Security check
Fill in the blanks below, or click a highlighted word in the prompt.
Review this landing page code for security issues: inline event handlers, unsafe innerHTML use, missing rel="noopener" on external links, form handling without CSRF or server validation, third-party scripts without integrity attributes, and exposed keys. List risks by severity and give a safer alternative for each.
[PASTE CODE]Multi-step workflow: build and verify
- Skeleton. Run prompt 1 in chat.
- Hero. Use the improved hero prompt, then paste the result into your file.
- Sections. Run prompts 2, 3 and 5. Use inline comments above empty blocks (for example,
<!-- Testimonial grid: 3 cols desktop, 1 mobile -->) to guide completions. - Review. Run prompts 9 and 11 on the full page.
- Test in real browsers, at several viewport widths, with a keyboard only and with an accessibility checker.

Tips and common mistakes
- Always review generated code. Read every line, run it, and test it.
- Never paste secrets such as API keys or customer data into chat.
- Check your organisation's policy on AI tools with private code.
- Name the stack and version so you do not get mismatched syntax.
- Prefer small snippets over whole pages for better accuracy.
- Common mistake: trusting generated validation as security.
- Common mistake: skipping alt text, labels and focus styles.
- Common mistake: copying libraries or licence-restricted code without checking.
