Yes, you can change your layout on Squarespace, and there are several ways to do so, depending on your specific needs and the version of Squarespace you are using. Below, I will outline the primary methods for changing your layout:

1. Switching Templates (Themes)

Switching your template is one of the most significant ways to change the layout of your Squarespace site. Note that this will affect the overall design and structure of your site, as templates come with pre-defined styles and layouts.

Steps to Switch Templates:

1. Log In: Log into your Squarespace account and open the website you want to modify.
2. Access Design Panel: Go to the design panel by navigating to Design on the left sidebar.
3. Template Menu: Click on Template.
4. Browse Templates: Click Install New Template to browse the available options. You can preview how each template looks and functions.
5. Install and Apply: Once you find a template you like, click Start with [Template Name]. Follow the on-screen instructions to install and then set it as your active template.

Considerations: - Switching templates will not delete your content, but it may alter how it's displayed. - Some customizations in your current template might not transfer over seamlessly.

2. Using Layout Pages

For more granular control without changing your entire template, you can use layout pages to arrange content blocks in various structures. This offers flexibility while retaining your existing template.

Steps to Edit Layout Pages:

1. Open Pages Panel: In the home menu, go to Pages.
2. Create/Edit Page: Either create a new page by clicking + or edit an existing one.
3. Add Sections: Click + to add a new section. Squarespace offers different pre-designed sections you can choose from, like 'About', 'Contact', 'Gallery', etc.
4. Edit Section Layout: Within each section, you can drag and drop blocks (text, images, videos, etc.) to adjust the layout.
5. Customize Settings: Use the section settings (gear icon) to customize the background, spacing, and other style preferences.

3. Custom CSS

For advanced users, custom CSS can be applied to tweak specific layout elements that are not easily configurable through built-in settings.

Steps to Add Custom CSS:

1. Go to Design Panel: Navigate to Design, and then click on Custom CSS.
2. Enter Code: Input or paste your CSS code into the text box provided.
3. Preview and Save: Use the preview function to see how your changes affect the layout before saving your modifications.

Considerations: - Custom CSS should be used cautiously, as incorrect code can lead to display issues. - It is advisable to have a basic understanding of CSS before attempting this method.

4. Sections and Content Blocks (Squarespace 7.1)

Squarespace 7.1 has more flexible layout options compared to earlier versions, allowing you to add and rearrange content blocks within sections more freely.

Steps for Squarespace 7.1:

1. Edit Page: Open the page you want to modify and click Edit.
2. Add/Edit Section: Add a new section or edit an existing one by clicking the section you want to modify.
3. Insert Blocks: Click + to add blocks like text, image, video, button, etc. Drag and drop these blocks to arrange them as desired.
4. Customize Block Settings: Click on any block to customize its settings, appearance, and layout options.

Limitations and Final Considerations:

• Compatibility: Some features and functionalities are specific to Squarespace 7.0 or 7.1, so check which version you are using.
• Backup: It’s always a good practice to backup your content before making significant changes.
• Learning Curve: Although Squarespace is user-friendly, there may still be a learning curve when customizing layouts, especially if you use custom CSS or complex configurations.

By utilizing these methods, you can efficiently change and customize your Squarespace site’s layout to better suit your needs, whether for aesthetic improvements, enhancing user experience, or adjusting functionality.
