}Alternatives to Squarespace CSS Codes
As we’ll discus later in this article, custom CSS codes are not risk-free.
The best alternative to using custom code is to use a plugin or extension that has an auto-update feature.
This means that the code will be updated whenever a new browser version is released, or Squarespace updates its service.
Spark Plugin
Spark Plugin is a no-code design tool that contains 100+ customizations for Squarespace websites.
With Spark Plugin, you don’t have to worry about your code ever breaking again.
There are some pretty nice customizations to choose from too.
Plugins and extensions
Plugins and extensions are often more sophisticated than little Squarespace code snippets and can be used as more safe alternatives to custom CSS code. Especially if they include an auto-update feature.
Here’s a super long list of Squarespace plugins.
FAQ - Squarespace Code Snippets
Can code snippets break my website?
Yes, custom CSS can break websites. Here are the three most common issues:
Squarespace updates its service. When Squarespace updates its services, your CSS code will stay the same. This can lead to a conflict between the two.
CSS code not tested in all browsers. While it might seem that the CSS code snippet works perfectly in your browser, it might have problems in other browsers.
CSS code not tested in mobile. Desktops and mobile use different screen sizes. On top of this, they treat functionality like hover- and touch very differently, which can lead to several issues.
Minimize the risk of site breaking due to code snippets
So should you stop customizing your website with Squarespace custom CSS and code snippets?
No, you can still use it if you consider these tips:
Use short Squarespace CSS codes. The longer the CSS snippets are, the higher risk it has of breaking.
Test your CSS snippets. Test in multiple browsers and mobile. This does not protect you from the future, but you have come a long way.
Use a plugin with auto-updating code, like Spark Plugin. The safest way to guarantee your site from not breaking is to use a plugin that updates the CSS codes for you. This is a must for high-visiting sites or sites that want high quality in general.
