Shopify No-Code Customization: Theme Editor Guide (2026)
To customize your Shopify store without code, open the theme editor (Online Store, then Edit theme on your theme) and change the store there: add, move and remove sections and blocks, set colors and fonts in the theme settings, and edit products and collections without leaving the editor. Every Shopify theme is built so that its design can be changed through sections and settings. Code is only for what no setting covers, and then a copy of the theme comes first.
Facts come from the Shopify Help Center pages on the theme editor, adding themes and metafields, read on October 23, 2026, and the page on templates, read on October 31, 2026.
Before you start: work on a copy
Your published theme is what customers see. Shopify lets you keep several themes in the Draft themes section of the Themes page, preview any of them, and share a preview link of an unpublished theme for feedback. Only one theme is published at a time, and the previous one stays in your themes list when you publish another.
For anything bigger than a text change, make your changes on a draft copy, preview it, then publish it. For small edits, the live theme is fine, because the editor shows every change in its preview before you click Save.
What you can change in the theme editor
The editor shows your store in a preview window with a sidebar of what the current page contains.
| Change | Where in the theme editor | Works on any theme? |
|---|---|---|
| Add, reorder, hide or remove a section (banner, featured collection, text, video) | The sections list in the sidebar | Yes, with the sections your theme offers |
| Add or change blocks inside a section (a button, a heading, a product detail) | Inside each section | Yes |
| Colors and color schemes | Theme settings > colors | Yes; options differ by theme |
| Fonts and font sizes | Theme settings > typography | Yes |
| Logo, favicon, social links | Theme settings | Yes |
| Product page layout | Switch to the product template with the menu at the top | Yes |
| Product, collection and other store data | Edit them inside the editor | Yes |
| Show a metafield, such as a care guide, on product pages | Connect a block to the metafield with Connect dynamic source | On themes that support dynamic sources |
| App features, such as a chat button or a popup | App embeds | Yes, for apps that provide an embed |
The color and typography settings apply across the whole store, so changing a color scheme once updates every section that uses it. That is faster than recoloring sections one by one, and keeps the store consistent.
Templates: one page or all pages of a type
The theme editor edits templates, not single products. Change the layout of the product template and every product that uses it changes. Use the menu at the top of the editor to switch between templates: the home page, Products > Default product, collections, pages, the cart.
When one product or page needs a different layout, such as a landing page for a campaign or a product with a size guide, create an additional template: open the Home page drop-down at the top of the editor, choose the template type, click Create template, name it and pick the template it is Based on. You then assign it in the admin, not in the editor: the product’s or page’s Theme template drop-down lists the templates of your live theme. Content that differs per product, like care instructions, belongs in a metafield connected to the template rather than in a separate template for each product.
Faster edits with Sidekick
Sidekick, Shopify’s assistant in the admin, works inside the theme editor too. Its Help Center page on generating theme blocks, read on October 31, 2026, describes the main job: click a section, then Add block and Generate, describe the block in at least five words (“a row of three icons with short delivery, returns and warranty notes”), preview it and click Keep. The block is saved as a Liquid file in the theme’s blocks folder and appears in the block picker. It works on Shopify Theme Store themes, but not on vintage themes or the Starter plan. Shopify warns that the generated code can contain errors and that its support does not troubleshoot it, so test the block on a phone and a desktop before you publish.
The Preview inspector lets you change a section by clicking it in the preview. It is on by default in Shopify’s free themes, with a toggle in the editor’s menu bar: click an outlined element in the preview to open its settings, or move, duplicate, hide or delete that section or block from the preview itself (preview inspector, read on October 31, 2026).
Shopify can generate up to three free personalized themes from a description of your business, in the Shopify app or a mobile browser. With an English storefront this works during the free trial or on the Basic, Grow or Advanced plan, not on Starter. It is a quick starting point if your current theme is far from what you want.
Some stores have access to Canvas, a separate editor. A theme with the Canvas badge on the Themes page opens only in Canvas and cannot be edited in the theme editor.
What still needs code or an app
- A layout the theme’s sections cannot produce, such as a section type your theme does not have.
- New behavior, such as a custom product configurator, a quantity rule or a calculation.
- Moving elements inside a section from another app, when that app’s block has no setting for it.
- Changes to a theme while it is on a paid-theme trial, since trial themes’ code cannot be edited.
The safe route for code: change a draft copy of the theme, use Edit code from the theme’s actions menu, and keep a note of what you changed. A theme update carries code edits over only when they don’t conflict with the new version; conflicting edits have to be copied into the new copy by hand. For large layout work, compare a page builder app with a developer in our guides to landing pages with a page builder and Shopify theme vs custom build.
Edits that cause trouble later
- Making large changes on the live theme during a sale.
- Uploading huge banner images. Shopify accepts product and collection images smaller than 20 MB, but a phone visitor still has to load what the page shows; resize banners to the size they display at.
- Installing a page builder app to change one banner the theme editor can already change.
- Forgetting that the theme editor edits templates, then wondering why every product page changed.

Frequently asked questions
Can I customize Shopify without coding? Yes. Shopify themes are built so that content, layout, typography and colors can be changed through sections and settings in the theme editor, without editing code. Code is only needed for layouts or behavior your theme’s settings do not offer.
Will my changes survive a theme update? Theme editor settings and code edits that don’t conflict with the new version carry over. Code edits that conflict are left out, and Shopify’s theme card says so, which is why a note of every hand-made edit saves time. How editor settings move to a new version is covered in our guide to theme updates and backups.
What is Shopify Canvas? Canvas is a separate editor that some stores have access to for creating and editing themes. A theme marked with the Canvas badge on the Themes page opens only in Canvas, not in the theme editor.
