Is anyone aware of how to format a single column in the grid questions? I’m trying to find a way to visually separate out the ‘Don’t Know’ column from the scale questions. This might be something than needs to be created with a CSS, but I’m yet to find a solution online.
This would have to be done with CSS. The basic element of an HTML table is the row (<tr>), so it is not possible to create a style just for a column. You will have to need something that you can apply to the final cell (<td>) in each row.
In SurveyGizmo, the last cell in a grid has the class “sg-last-cell”, so this would be the class for which you will need to target your custom CSS.
