Reverting Site Styles Changes
If You Know the Original Values
Go to Design > Site Styles and re-enter your previous font names, hex color codes, font sizes, and spacing values. If you documented your settings before making changes (screenshots or written notes), use that documentation to restore each value.
If You Do Not Know the Original Values
If you did not document your settings and want to return to the template's factory defaults, there is no one-click reset button in Site Styles. You can: look at the template's demo site for reference values, install a fresh trial site with the same template to see the defaults, or use browser DevTools to inspect the template's default CSS for specific values.
Resetting to Template Defaults (7.0)
On 7.0, some templates have a "Reset Styles" or "Default" option within specific Site Styles categories. Check each section of Site Styles for a reset button. Not all templates offer this, and it resets the entire category - not individual settings.
Reverting Custom CSS Changes
If You Have a Backup
Open Design > Custom CSS and replace the current CSS with your backup file contents. Save. This instantly restores your previous styling. This is why backing up CSS before making changes is critical. For CSS management, our guide to Squarespace custom CSS covers backup and organization practices.
If You Do Not Have a Backup
If you added CSS and want to remove it, simply delete the CSS rules you added. If you do not remember which rules are new, look for rules without comments (if you comment your CSS) or delete everything and start over with a clean Custom CSS editor. Deleting all Custom CSS restores the template's default appearance for everything CSS controlled.
Removing All Custom CSS
If your Custom CSS has accumulated over time and you want a clean start, select all text in Design > Custom CSS and delete it. Save. Your site reverts to the template's default styling for all elements CSS was overriding. You can always re-add specific rules later.
Reverting Template Changes (7.0)
Switching Back to Your Previous Template
On 7.0, go to Design > Template, find your previous template, and install it. Your content carries over. Site Styles reset to the old template's defaults (not your previous configuration). Custom CSS needs selectors updated to match the old template again. For detailed reverting guidance, our guide to going back after switching templates covers the process.
Reverting Page Layout Changes
Using Ctrl+Z (Limited)
Within a single editing session, Ctrl+Z (Cmd+Z on Mac) undoes recent changes in the Squarespace editor. This works for block additions, deletions, and repositioning - but only within the current session. Once you save and close the editor, the undo history is gone.
Rebuilding from Screenshots
If you have screenshots of your previous layout, use them as reference to rebuild sections. This is manual work - no automatic restoration exists for layout changes. This is another reason to screenshot your design before making significant changes.
Reverting Code Injection Changes
If you modified Code Injection (Settings > Advanced > Code Injection) and want to revert, restore the previous contents from your backup. If you do not have a backup, remove the recently added code. If you are unsure what was added recently, remove all Code Injection and test - then re-add only the scripts you know are needed (analytics, fonts, etc.). For Code Injection management, our guide to custom code injection on Squarespace covers safe practices.
Starting Completely Fresh
New Site, Same Template
If your customizations have become too tangled to revert, create a new Squarespace site with the same template. This gives you a clean starting point with factory-default styling. Rebuild your content on the fresh site and transfer your domain when ready.
New Site, Different Template
If you want both a fresh start and a new design direction, create a new site with a different template. This is the most dramatic approach but sometimes the fastest when existing customizations have created more problems than they solve. For template selection, our guide to choosing a Squarespace template covers evaluation criteria.
Preventing the Need to Revert
Document before changing. Screenshot your design and write down Site Styles values before every significant change. Five minutes of documentation prevents hours of reverting.
Comment your CSS. Add comments with dates to every CSS rule: /* Added 2026-03-30 - Custom heading color */. This makes it easy to identify and remove specific changes.
Make one change at a time. Adjust one setting, preview, and save. Then adjust the next. Making ten changes at once makes it impossible to identify which change caused a problem.
Use a staging approach. If possible, test design changes on a trial site before applying them to your live site. Squarespace's 14-day free trial lets you create a test site for this purpose. For design strategies, our Squarespace design tips guide covers safe design workflows. For mobile testing, our guide to Squarespace mobile optimization covers verifying changes on all devices. For broader site management, our guide to customizing your Squarespace website covers the full customization process.

Your Documentation Is Your Undo Button
Squarespace does not have a site-level revert feature. Your ability to go back to your original style depends entirely on whether you documented it before making changes. Screenshots, written settings, and CSS backups are your rollback plan.
If you are reading this after making changes you regret: restore what you can from memory or reference, delete CSS you do not want, and accept that some manual rebuilding may be needed. If you are reading this before making changes: document everything first. Five minutes now saves hours later.
