In this tutorial, Kate from Lending explains how to add custom code to a landing page. To implement JavaScript code, users should access the dashboard, click the 'Add Script' button, and name the code for easy identification. Users can paste their code and specify the page it applies to before clicking 'Add.' JavaScript codes can be utilized for additional tracking tools like Google Tag Manager, Google Analytics, Facebook Pixel, or heat maps. CSS and HTML codes can also be incorporated: additional CSS through the page settings via the 'Custom CSS' button, and an HTML widget can be dragged and dropped from the editor’s left side. By double-clicking the widget, users can paste their code. Once published, elements added through HTML will be visible on the landing page. For assistance, users can contact the support team.
