# Custom Liquid

{% hint style="warning" %}
**We do not support code customizations**. This guide offers a basic reference for advanced users familiar with HTML and Liquid. Always test code changes on unpublished theme copies. For assistance, we recommend reaching out to a [verified Fluorescent partner](https://partners.fluorescent.co/).
{% endhint %}

With the **Custom Liquid** setting, you can extend your theme by adding snippets of Liquid or HTML code as a block or section in the theme editor.

Custom Liquid provides a reliable and safer option compared to directly editing your theme code. It will help keep your theme copy eligible for updates and avoid conflicts with the original theme code.

This guide shows how to add a Custom Liquid section and provides an example for adding anchor links to sections.

## **Add Custom Liquid section**

***

Follow the steps below to add Custom Liquid section and test your custom code.

{% hint style="success" %}
Liquid is the template language used by Shopify. See their [Liquid reference guide](https://shopify.dev/docs/api/liquid) to learn more. Also check out Shopify's [Liquid code examples](https://shopify.github.io/liquid-code-examples/).

## **Add anchor links to sections**

***

{% hint style="info" %}
Shopify dynamically generates ids for sections but these ids are not stable. The following instructions are a workaround for this platform limitation.
{% endhint %}

To link to a specific section on a page, you can use a **Custom Liquid** section with some HTML as a workaround. The HTML will include a special **`id`** property that will allow you to link directly to that section.

Once set up, the Custom Liquid section will not affect the page layout.

{% hint style="warning" %}
**Anchor link in the Header doesn't work?** If your anchor link in the navigation menu points to a section on the same page, you will need to disable page transitions for the link to work. Go to **Theme settings > Animation** and deselect **Enable page transitions**.
{% endhint %}

<summary><mark style="color:blue;"><strong>STEPS</strong></mark></summary>

In your theme editor (**Customize**):

1. Under **Template**, click **(+) Add section** and select **Custom Liquid**.
2. Click and hold the drag and drop handles **`⋮⋮`** to move the Custom Liquid section directly above the section you want to link to.
3. Click the **Custom Liquid** section to open the settings.
4. Enter the following HTML code and enter a unique **`id`** property in the opening tag. If using multiple words, you must use dashes (`-`) instead of spaces.

   > **`<span id="our-values"></span>`**

   > Recommended: Use an ID that's the same name as your section, and make sure the name is not used by other IDs.

   > **`div {padding: 0px; margin: 0px;}`**

6. Find and click the section or block that will link *to* the Custom Liquid section.
7. In the link field, enter the **`id`** with a hashmark at the start (e.g. **`#our-values`**).

   > To **link from another page or menu link**, you must enter the full URL path with the anchor link at the end (e.g. **`www.store.com/#our-values`** or **`www.store.com/about#our-values`**).

8. <mark style="background-color:orange;">If adding the anchor link to the navigation menu</mark>, you will need to disable **Page transitions** in **Theme settings > Animation**. Otherwise, the link will not work for sections that are on the current page.
9. Click **Save**.
