Theme settings on your forms

There are various theme options in our online form designer. Basically, you can change just about anything on your web form, from text font and color to the style of the submit button. The settings categories that you can tweak in the theme customization panel are Quick setup, Layout, Background, Fields and Buttons.

Now let’s get right into it and see how you can customize your theme in each category.

  1. How do you incorporate a semi-transparent background? For example, I’d like to incorporate a transparent blue to my form’s background.

    1. Hi Cyle! You can add the transparent background from the forms Design -> Form -> Background option. There you will find a color picker where you can select the desired shade of blue and below that, you can also set the transparency of that shade. If you already have the HTML code of your preferred color, you can add it in the text area of the color picker and the form will change accordingly.
