Position of validation error message

No.. Appian does not give control over individual CSS properties... What you can do is position validation errors on sections, forms layouts, or individual fields..

And you can also trigger additional text to be rendered..

If you want a highly custom validation message to appear, suggest using the Rich Text Component..

docs.appian.com/.../Rich_Text_Component.html

This will give you styling control over some text in your form.. such as color (red, green, black, grey).. size.. alignment (right, left, center) etc.. You could also include bullets and links..

You can use the showWhen parameter to show the rich text message on a certain condition..

But note, you will still need to use validation configuration on the fields or layouts, as validation will have the extra benefit of preventing a form submission until the validation errors are resolved.

Thanks so much Malcolm, I tried using the layout validations and shifted some boxes in new sections. Totally worked.
