If you’ve spent any time working inside Shopify lately, you’ve probably heard the terms sections and blocks being mentioned, maybe even in some of Shopify’s latest announcements. But when you log into your theme, you might not see them right away, and it can feel a little confusing.
In the video below, break down exactly what these new building elements are, how they work together, and why they’re such a big deal for store owners and developers alike.
What Are Sections and Blocks?
Let’s start simple.
- Sections are the major building areas on a page, like your header, featured collection, or footer.
- Blocks are the smaller, reusable components that live inside those sections, think of them as the “Lego pieces” that make up your page.
Until recently, these blocks were tied to the specific section they were created in. In other words, if a theme had a “button” or “heading” block, you could only use it within that section. But now, Shopify has opened things up, blocks can be reused across your entire store.
That change unlocks a ton of flexibility. You can take a single block like a button or image layout, and apply it anywhere you need it, without having to recreate it each time.
A Practical Example
Imagine you’re editing your homepage. You have three sections visible: a large logo area, a hero banner, and a featured collection. Inside each section are blocks: the logo itself, the heading text, and a call-to-action button.
Now, instead of building those elements from scratch for each new section or page, Shopify lets you use the same block type across your site. You can drag, drop, and customize it wherever you need.
This streamlines how your theme is built and maintained. For teams managing multiple pages or running frequent seasonal updates, it saves time and keeps your brand presentation consistent.
Why Developers and Agencies Love It
For developers and Shopify partners, the new block system speeds up workflow dramatically.
Before, creating a variation of an existing feature, like a slightly different button or product tile, required editing a theme section and potentially duplicating code. Now, a developer can copy an existing block, make improvements, and save it as a new reusable element.
Because these blocks are standalone bits of code, they’re upgrade-safe, meaning that when you update your theme, your custom blocks don’t disappear. You keep all your added functionality intact while still benefiting from theme updates.
It’s a win-win: faster development, cleaner code, and fewer headaches during future upgrades.
The Power of Custom Sections
Shopify has also introduced a “Custom Section” type that lets you access all your available blocks in one place. This opens up even more creative freedom for your layouts.
You can now use layout blocks to group content horizontally or vertically — essentially giving you control over multi-column designs right inside the theme editor.
Want a two-column layout featuring text on one side and a product image on the other?
You can do that visually, without writing a line of code.
These layout tools make it possible for merchants to create flexible, on-brand pages that previously would have required a developer’s help.
Why This Matters for E-Commerce Teams
For e-commerce managers running medium to large stores, this evolution in Shopify’s theme structure has huge implications. It means faster updates, easier collaboration between marketing and development teams, and greater control over how your store looks and feels.
Reusable, upgrade-safe blocks reduce the risk of accidental errors when editing themes and make it easier to maintain consistency across campaigns, landing pages, and product launches.
It’s one more step toward Shopify’s vision of being a platform where creative teams can work quickly and safely, without having to touch complex code each time they need to tweak the design.
