The Visual Customizer Workspace

Navigate to Storefront > Visual Builder (`/storefront/builder`) in your merchant dashboard. The interface is engineered as a high-productivity split-screen studio:

- Left Configuration Panel: Structured tabs covering all visual and functional components of your active storefront theme.

- Center Live Canvas: Real-time, sandboxed rendering of your storefront that reacts instantly as you adjust color pickers, typography selectors, or banner toggles.

- Top Utility Bar: Device viewport switchers, direct link to live storefront, reset to template defaults, and the one-click "Save & Publish" button.

Multi-Device Viewport Preview (Desktop, Tablet, Mobile)

Because mobile shoppers represent the vast majority of online transactions, you must ensure your store looks flawless across every screen size before publishing changes.

Use the three viewport buttons at the top of the canvas to toggle preview modes on the fly:

Supported Viewport Modes in Theme Customizer

Mobile375px compact smartphoneSticky bottom navigation bar, single or 2-column product cards, tap targets, mobile drawer menu, and announcement banner text wrapping.

Color Tokens & Curated Palette Presets

Teyweb uses a CSS custom property (variable) design token architecture. When you change a brand color, every button, badge, link, active tab, and focus ring updates consistently across all storefront templates.

You can fine-tune individual hex codes or click any of our curated one-click color presets:

Typography Engine & Google Font Pairings

Typography defines brand personality and reading comfort. The customizer provides curated Google Fonts pairings loaded asynchronously from edge CDN servers to avoid render-blocking delays:

- Modern / Clean: Inter (Body) paired with Plus Jakarta Sans or Outfit (Headings).

- Luxury / Editorial: Playfair Display, Cormorant Garamond, or Merriweather paired with clean sans-serif body text.

- Geometric / Tech: Roboto or Poppins paired with Space Grotesk or Nunito.

You can adjust font weights, heading letter-spacing, and text sizes while previewing real product descriptions live on screen.

Hero Banners, Carousels & Contrast Overlays

Your hero banner is your primary conversion engine. Under the Hero tab, configure:

- Hero Mode: Choose between a Single High-Impact Banner or a Multi-Slide Carousel (supporting up to 5 rotating slides with adjustable auto-scroll interval).

- Background Media: Upload landscape photography (recommended size: 1920x800px) or choose from high-resolution curated backdrop presets.

- Overlay Contrast Slider: Add a semi-transparent black or dark-gradient backdrop overlay (from 0% to 80% opacity) to guarantee headline legibility over busy photos.

- Action Call-to-Actions (CTAs): Configure Primary and Secondary buttons linking directly to specific Collections, Categories, or Custom Pages.

Homepage Sections Ordering & Visibility

Tailor your storefront homepage layout by reordering and toggling modules with the Move Up and Move Down controls:

Key Takeaways

  • Hero Banner: The top promotional slider or video banner.
  • Category Slider / Pills: Quick horizontal category navigation allowing shoppers to filter products with a single tap.
  • Featured Products: Curated 4 to 12 bestseller showcase.
  • Promotional Collections: Seasonal campaign banners (e.g. "Ramadan Essentials", "Black Friday Drops").
  • Brand Story / Manifesto: Narrative block explaining your brand heritage and quality promise.
  • Verified Customer Reviews: Social proof slider displaying 5-star verified buyer ratings.
  • Newsletter Subscription: Email capture card for email marketing outreach.

Product Display, Aspect Ratios & Sorting

Control how your catalog listings appear across collection and search pages:

- Image Card Aspect Ratio: Select Square (1:1), Portrait (4:5, optimal for fashion and clothing), or Wide (16:9, optimal for electronics and appliances).

- Image Fit Mode: "Cover" fills the card completely; "Contain" ensures full product borders are visible without cropping.

- Default Catalog Sorting: Choose between Newest Releases, Most Popular, Price: Low to High, Price: High to Low, or Alphabetical (A-Z).

- Stock Level Indicators: Toggle low stock warning badges (e.g. "Only 3 left in stock!") to drive purchase urgency.

Saving, Publishing & Resetting Defaults

As you make changes, the live preview updates immediately in memory without modifying your public store.

When you are ready, click "Save & Publish" in the top action bar. Changes propagate across edge CDN nodes in seconds.

If you ever want to revert your styling back to the original theme defaults, click the "Reset to Defaults" button to restore factory layout and colors.
