Theme & Design Handbook

A storefront that looks designed on purpose — built entirely in the visual editor.

What's inside

• What a theme actually is: sections, blocks, templates and settings
• Choosing a theme: free flagship versus paid, and the checks to run before buying
• Safe editing and versioning — duplicate before changing, and why customisations get lost
• Type: choosing at most two typefaces, and the sizes that stay readable on a phone
• Colour: a five-token palette, contrast minimums, and why one accent beats six
• The homepage, section by section, in the order shoppers read it
• Product page layout and what belongs above the fold
• Collection and search pages — the pages everyone forgets
• Navigation and footer structure
• A concrete mobile checking pass
• The five things that actually make a storefront slow, and how to fix each
• A full design review checklist

Who it's for

Store owners who want a storefront that looks professional and can still be updated safely. Not for developers looking for Liquid tutorials — there is deliberately no code in this book.
