Squarespace Custom Layout

Custom Layouts Using the Squarespace Visual Editor

Section-Based Layout Control

Every Squarespace page is built from sections stacked vertically. Each section has its own background, padding, content width, and alignment settings. The foundation of any custom layout is understanding how to configure sections independently, giving each one a different visual treatment while maintaining a cohesive page flow.

Configure section width (full-bleed vs. contained), padding (top and bottom spacing), and background (color, image, or video). Alternating between full-width and contained sections creates visual rhythm. Alternating background colors creates clear separation between content areas.

Column Layouts Within Sections

In Squarespace 7.1, you can create multi-column layouts by dragging content blocks side by side within a section. The editor supports up to four columns with drag-based width control. For equal-width columns, place blocks side by side and the editor distributes the space evenly. For unequal columns, drag the column divider to adjust proportions.

This built-in column system handles most layout needs: two-column text and image layouts, three-column feature grids, and four-column icon sections. For layouts that need more than four columns or specific pixel-width columns, you will need Custom CSS.

Custom Squarespace Layouts Using CSS Grid and Flexbox

For layouts that the visual editor cannot produce, CSS Grid and Flexbox give you complete control over element positioning, spacing, and responsive behavior. Add your CSS rules to Design > Custom CSS and they override the template's default layout styles.

CSS Grid for Complex Page Structures

CSS Grid lets you define a two-dimensional layout with rows and columns of any size. You can create layouts where content spans multiple rows or columns, where elements overlap, or where the grid structure changes entirely at different screen sizes. Target a specific section by its data-section-id attribute and apply a grid layout to its content container.

For example, to create a two-column layout where the left column takes up one-third of the width and the right column takes two-thirds:

.page-section .content-wrapper { display: grid; grid-template-columns: 1fr 2fr; gap: 40px; }

Flexbox for Alignment and Distribution

Flexbox is ideal for one-dimensional layouts: aligning items in a row or column with precise control over spacing, alignment, and wrapping. Use it to center content vertically within a section, distribute items evenly across a row, or create a responsive card layout that wraps from three columns on desktop to one column on mobile.

Custom Layouts Using Code Blocks

Code Blocks let you insert completely custom HTML structures into your page. This is the most flexible layout method: you can build any structure that HTML and CSS support, from pricing comparison tables to team member grids to interactive portfolios.

Building a Custom HTML Layout

Add a Code Block to your page and write your HTML structure. Use div containers with custom classes, then style them with CSS in the Custom CSS editor. This approach gives you a layout that is completely independent of the Squarespace template: it renders exactly as your HTML and CSS define it.

For example, a custom three-card layout:

<div class="custom-cards"><div class="card">Card 1 content</div><div class="card">Card 2 content</div><div class="card">Card 3 content</div></div>

Then in Custom CSS: .custom-cards { display: grid; grid-template-columns: repeat(3, 1fr); gap: 30px; } .card { padding: 30px; background: #f5f5f5; border-radius: 8px; }

When to Use Code Blocks vs. CSS Overrides

Use CSS overrides when you want to modify how existing Squarespace blocks arrange themselves on the page. Use Code Blocks when you need a completely new HTML structure that the editor cannot create. CSS overrides are easier to maintain because they work with the existing content. Code Blocks are more powerful but require managing your own HTML alongside the Squarespace editor. For code implementation details, our guide to adding custom code to Squarespace covers both approaches.

Responsive Custom Layouts in Squarespace

Every custom layout must work on mobile. Desktop layouts with multiple columns need to collapse to single-column on small screens. Elements with fixed widths need to switch to percentage-based or fluid widths. Hover effects need touch-friendly alternatives.

Using Media Queries

Add CSS media queries to your Custom CSS to define different layout rules at different screen widths. Squarespace's mobile breakpoint is typically around 640 to 768 pixels. At that breakpoint, switch multi-column layouts to single-column, reduce padding, and increase font sizes for readability on small screens.

@media screen and (max-width: 768px) { .custom-cards { grid-template-columns: 1fr; } }

Testing Responsive Layouts

Use the Squarespace mobile preview as a starting point, but always test on actual mobile devices. The preview approximates the mobile experience but does not perfectly replicate touch behavior, scroll performance, or real-world rendering. Check your custom layouts on at least one iOS and one Android device. For mobile-first design strategies, our Squarespace design tips guide covers responsive layout principles.

Squarespace Custom Layout Ideas

Split-screen hero section: Image on one side, text on the other, each taking exactly 50% of the viewport width. Use CSS Grid with two equal columns and min-height: 100vh for a full-screen effect.

Overlapping elements: Text overlapping an image, or a card overlapping two adjacent sections. Use CSS position: relative with negative margins or transform: translateY(-50px) to create overlap effects.

Masonry grid: A Pinterest-style layout where items have different heights and fill available space dynamically. Use CSS Grid with grid-auto-rows: min-content or a JavaScript masonry library.

Sticky sidebar: A content area that scrolls while a sidebar element stays fixed. Use CSS position: sticky; top: 100px; on the sidebar element.

Full-width section within a contained page: Break out of the content container for a single section using width: 100vw; margin-left: calc(-50vw + 50%); to span the full browser width.

Common Custom Layout Mistakes to Avoid

Most custom layout issues on Squarespace come from a handful of recurring mistakes. Knowing them upfront saves significant debugging time.

• Targeting the wrong CSS selector: Squarespace generates unique section IDs and class names that can change when you edit your site. Always use the browser's inspector to confirm the exact selector before adding CSS. A selector that works today may break after a template update.
• Fixed pixel widths on mobile: If you set a Code Block element to width: 800px;, it will overflow on mobile screens. Use percentages (width: 90%) or max-width with auto margins (max-width: 800px; margin: 0 auto;) instead.
• Forgetting !important for overrides: Squarespace template styles are often more specific than your custom rules. When your CSS does not appear to work, add !important to the property you are trying to override. Use it selectively: too many !important declarations make your CSS hard to maintain.
• Not testing in Safari: CSS Grid and Flexbox behavior can differ between Chrome and Safari, particularly with older Safari versions. Any custom layout using Grid or Flexbox should be tested in Safari before going live.
• Editing Code Blocks on a mobile device: The Squarespace mobile app does not fully render Code Block content in edit mode. Always make Code Block edits from a desktop browser to avoid broken layouts.

Build Pages That Match Your Vision

Custom layouts are what separate a Squarespace site that looks like a template from one that looks like a professionally designed brand experience. Start with the visual editor's built-in column controls for simple layouts, use Custom CSS for grid and flexbox-based structures, and reach for Code Blocks when you need something the editor cannot produce.

Every layout should be responsive, tested on mobile, and intentional in its design. A custom layout that breaks on half your visitors' devices is worse than the default. Build carefully, test thoroughly, and your pages will stand out for the right reasons.
