Frequently asked questions

Have confusions? Don't worry. Check out some of the commonly asked queries.

What language is Shopify theme development?
Shopify themes are built with Liquid (Shopify's templating language), HTML, CSS, and JavaScript. Liquid is a simple, readable templating language that connects your theme to Shopify's data (products, collections, customers, etc.).
What is Online Store 2.0?
Online Store 2.0 (OS2) is Shopify's current theme architecture, launched in 2021. It enables sections and blocks on any page (not just the homepage), JSON templates, and the new theme editor with app blocks. All new Shopify themes are built on OS2.
How long does custom Shopify theme development take?
A standard custom Shopify theme takes 4–8 weeks from design approval to delivery. Complex themes with extensive custom sections and functionality take 8–12 weeks. See our custom Shopify theme service for details.
