Example

Here’s an example of how to create a PageHTML plugin with custom styling: 
const welcomeMessage = new PageHTML({
    content: `
        <div class="welcome-message">
            <h2>Welcome to Our Customer Satisfaction Survey</h2>
            <p>Your feedback is important to us. This survey will take approximately 5 minutes to complete.</p>
            <ul>
                <li>All responses are anonymous</li>
                <li>Please answer all questions honestly</li>
                <li>If you have any issues, please contact our support team</li>
            </ul>
        </div>
    `,
    position: 'top',
    styles: {
        '.welcome-message': {
            backgroundColor: '#f0f8ff',
            padding: '20px',
            borderRadius: '8px',
            marginBottom: '20px',
            boxShadow: '0 2px 4px rgba(0,0,0,0.1)'
        },
        '.welcome-message h2': {
            color: '#2c3e50',
            marginBottom: '10px'
        },
        '.welcome-message p': {
            color: '#34495e',
            marginBottom: '15px'
        },
        '.welcome-message ul': {
            paddingLeft: '20px'
        },
        '.welcome-message li': {
            marginBottom: '5px'
        }
    }
});

survey.addPlugin(welcomeMessage);

// Later, if you need to update the content:
welcomeMessage.updateContent(`
    <div class="welcome-message">
        <h2>Thank You for Completing Our Survey</h2>
        <p>Your responses have been recorded. We appreciate your time and feedback.</p>
    </div>
`);
