How to Add Custom Code to Squarespace for Unique Features

Squarespace is a powerful platform for building stylish websites with ease, but sometimes you need a little something extra that the built-in tools don’t offer. That’s where custom code comes in. With a few tweaks, you can make your Squarespace website stand out with unique features that elevate your brand and improve user experience.

Here’s a beginner-friendly guide to adding custom code to your Squarespace site.

1. When and Why to Use Custom Code

Squarespace has a wide range of built-in features, but you might want to use custom code if you want to:

• Add design flourishes not possible with the default styles

• Integrate third-party services or widgets

• Add functionality like pop-ups, countdown timers, or tabbed content

• Tweak layouts or hide elements on certain screen sizes

If you're looking to push beyond what the template allows, a small piece of code can go a long way.

2. Where to Add Custom Code in Squarespace

Code Injection (Site-Wide)

Go to Settings > Advanced > Code Injection

• Header: Good for adding CSS, tracking scripts (e.g. Google Analytics), or fonts.

• Footer: Ideal for adding JavaScript just before the closing body tag.

Page Header Code Injection (Per Page)

• Edit the page, then click the settings ⚙️ icon and go to Advanced.

• Useful if you only want code to apply to one page.

Code Blocks (Within Pages or Sections)

• Use a Code Block to embed HTML, CSS, or JavaScript directly on a page.

• Great for embedding widgets, forms, or styled content.

Custom CSS

• Navigate to Design > Custom CSS to apply site-wide visual changes.

• This is perfect for adjusting spacing, changing fonts or colours, or hiding unwanted elements.

3. Common Examples of Custom Code

Example 1: Hiding the Image Overlay on Hover

.image-overlay {
  display: none !important;
}

This removes the dark overlay that appears when you hover over images in some templates.

Example 2: Centre Align Navigation Links

.Header-nav-list {
  justify-content: center;
}

Adjust the alignment of your navigation menu for a cleaner look.

Example 3: Embed a Third-Party Widget

Paste this in a code block or footer:

<script src="https://example.com/widget.js"></script>

Make sure you trust the source and test functionality before publishing.

4. Important Tips and Warnings

• Test First: Make changes in a duplicate page or during off-peak hours.

• Use Comments: Label your code to keep track of what each section does.

• Keep a Backup: Always save a copy of your custom code in a safe place.

• Be Aware of Updates: Template or platform updates might affect how custom code behaves.
