Recently while working with Gravity Forms on a project – we needed to set up a large form that would span two columns. Since this is something common – I decided to look first at the Gravity Forms documentation.
Per the documentation I found this:
In Gravity Forms 1.5 we added “Ready Classes”. Using these new classes, you can easily create more advanced alternative layouts for the fields in your forms. Essentially, Ready Classes are class names that you can add to the parent element surrounding each field to take advantage of pre-defined styles included in the default form stylesheet.
By simply adding a new class to your form field (Advanced > Custom CSS Classes) – you can easily create columns (2 or three) without any custom CSS classes to worry about. In seconds – I had the style I needed!
If you are looking to customize the layout for your Gravity Forms forms – do yourself a favor and read the following documentation: https://www.gravityhelp.com/documentation/article/css-ready-classes/ as it will save you a lot of time and frustration.
