This feature is optional - you do not need to know HTML to use Anvil!
However, if you do know HTML, or employ a web designer who does, this reference will allow you or them to create a beautiful template into which you can easily drag-and-drop your Anvil components.
You can set the raw HTML of a Custom HTML form to anything you like by clicking the ‘Edit’ button in the Properties Panel
This will open the HTML Editor at the bottom of the Form Editor, and you can expand the panel by clicking the separator bar:
As you edit the HTML, you will see the changes appear live in the Form Editor above. You can designate slots in the HTML to support dragging and dropping new components into your custom Form - see Custom HTML Templates for details.
You can include any custom HTML you like into your form, including
<style> tags, but if you are including third-party scripts then you should probably be using the Native Libraries feature to ensure they are loaded at the right time. For custom styles, you may prefer to edit the main style of your app instead.
