If the standard styling and templates are not enough, you can apply custom CSS code to ensure that the Flow matches your branding.
Update the CSS code
To open your Flow’s visual settings, go to Visual Marketing → Flows, then click Settings on the Flow you want to edit. The button appears on the right side of the screen. Then, click on the CSS tab that appears on the left-hand menu.
Write your CSS code in the text box. Your updates will be applied automatically and immediately.
Don`t forget to save your code by clicking on the “Save” button on the top right corner of the screen.
