Hello and thank you for quick responce. Unfortunatelly there are not any according settings. Can you provide me css but only for the newsletter forms, not e.g contact forms?
thank you
When you enter the text it is orange. The placeholder (the default text) is white cause you have activated the dark scheme. The placeholder can be set once and for the whole site by its nature, if I change the color on the white background, the placeholder would become invisible in other files as well.
