Usage

Add the form to your HTML

Default ID: #turbofan-form

Add the barebones subscription form and extend it to your liking:

<form id="turbofan-form" action="https://api.turbofan.email/v1/form/FORM-ID-HERE/register" method="post">
	<input name="email" type="email" autocomplete="email" required>

	<button type="submit">Sign up</button>
</form>

Or add the extended form to start with:

<form id="turbofan-form" action="https://api.turbofan.email/v1/form/FORM-ID-HERE/register" method="post">
	<label for="firstname">Your first name</label>
	<input id="firstname" name="firstname" type="text" autocomplete="given-name" required>

	<label for="email-address">Your email</label>
	<input id="email-address" name="email" type="email" autocomplete="email" required>

	<button type="submit">Sign up</button>

	<div class="spinner turbofan-hidden">Sending ...</div>

	<p class="success-msg turbofan-hidden">Thank you, please <span class="inbox-link">check your inbox</span> to confirm your subscription!</p>
	<p class="error-msg turbofan-hidden">Error, please try again later.</p>

	<p>By clicking the button above, you agree to our <a href="/privacy/" target="_blank">privacy policy</a> and for the use of your email address to receive our newsletter.</p>
</form>

Here, the optional elements are used:

• Loading spinner (default class: spinner)
• Successful signup (default class: success-msg)
• Error during signup (default class: error-msg)
• Inbox link placeholder (default class: inbox-link)

Note that if you don't have CSS helper classes for hidden elements or hidden for screen readers only, you can include the optional stylesheet before </head>:

<link href="style.css?v=0.1.1" rel="stylesheet">

(optional) Add an error message to your confirmation page

<div id="turbofan-confirm">
	<p class="error-msg turbofan-hidden">Error, please try again later.</p>
</div>

	apiHost: 'https://api.turbofan.email',
