Custom Liquid

An empty section that renders whatever you put in it. It is the escape hatch. When nothing in the theme does the thing you need, this will do it.

What it does: Takes code and renders it as a section of the page, with the theme’s own spacing and color scheme around it. That can be an app’s snippet, a third-party widget, or Liquid you have written.

Key settings (the whole section):

Setting	What it does	Default
Color scheme	Section colors. Your code inherits them, so a snippet that uses the theme’s own classes matches the rest of the page.	scheme-paper
Code	The snippet. Liquid, HTML and inline styles all work.	A short provenance note
Full width	Runs the content to the edge of the screen instead of keeping it in the page’s text column.	Off

The section also carries a Section spacing group. Pick a Device of Desktop or Mobile, then set Top and Bottom padding from 0 to 200px. Desktop starts at 96px and mobile at 56px.

Blocks: a Custom Liquid block, so one section can hold several separate snippets.

Tip

Use the theme’s own classes and it will look like the theme. t-label sets the small capitalized line, and wrapping copy in <div class="rte"> gives it the theme’s paragraph spacing, list styling and link underlines. The code this section arrives with is a worked example of both.

Caution

This is the one section that can break a page. Unclosed tags, a stray {% %}, or a script that fails will take out the layout around it. Nothing checks what you paste. Add it, save, and look at the page on a phone as well as a desktop before you leave it there.

Caution

Most apps do not need this. A properly built Shopify app offers an app block you add through Add block or Add section like anything else, and that keeps working when the app updates. Reach for pasted code only when the app gives you a snippet and no block.

When to use it: Use it for an app widget with no block of its own, a piece of structured data, or one-off markup. If you find yourself pasting the same snippet onto several pages, that is a sign it belongs in the theme rather than in a section. Support can tell you whether the theme already does it.
