Hello WOWembossing,
Thank you for reaching out to Constant Contact API Developer Support. My team is here to assist outside software developers with questions about building into Constant Contact's API.
I’m sorry for any difficulty you’ve experienced with customizing your inline sign-up form. Our inline forms don’t currently have an option to customize the size/style of of the form, however, I have tracked your feedback on a feature request for the ability to do so.

If you require a form that allows for further customization options, you would need to use a 3rd party form that meets your customization requirements. You can either search for a 3rd party form online that is compatible with Constant Contact and your website host, or check the Integrations page within your Constant Contact account.
If you're interested in developing your own form, you can connect it using Constant Contact's V3 API:

Please have a look and let us know if you have any other questions!
