Using advanced customizations can give you nearly unlimited control over the appearance and functionality of your website by allowing you to introduce bespoke styles or third-party integrations. However, using custom code is not always easy for people who consider themselves "technically-challenged" or just plain busy. Although Squarespace provides a wide range of general guides and advice, one of the best places to find answers to specific problems is through the Community Answers forum, so don't be afraid to reach out if you get stuck. If you can't get the answers you need there, remember that most designers/developers who use Squarespace tend to have small businesses that offer reasonably priced services, so it may be worth investing in professional assistance to help bring your Squarespace website to its full potential.
