Adjust button appearances to complement your design
Create hover and focus effects for enhanced user interaction

Whether you're a CSS novice or an experienced coder, this tutorial will provide you with the tools and knowledge to elevate your Squarespace forms. We'll walk through each step, explaining the code and its effects, so you can understand not just what to do, but why you're doing it.
