🧊Components

The majority of components come from our open-source package "Petal Components". However, there are some only in Petal Pro. Ultimately, petal.build will house all docs related to components, and these guides will more tailored to Petal Pro core functionality.

Layouts

Docs are on petal.build.

Brand

See the Branding section.

Color scheme switch

<.color_scheme_switch />

The switch to switch between light and dark mode.

Note that for this to work you also need to add this to your <head> . This is installed by default in Petal Pro.

# in your <head>:
<.color_scheme_switch_js />

Email helpers

A set of components for email templates. Kind of like Petal Components, but for emails.

Example usage:

<h1>Let's verify your account</h1>

<p>Touch the button below to verify your account</p>

<EmailComponents.button_centered to={@url}>
  Verify account
</EmailComponents.button_centered>

<EmailComponents.small_text>
  If you didn't create an account with us, please ignore this.
</EmailComponents.small_text>

If you want to add your own components, you can edit the following file:

/lib/petal_pro_web/components/email_components.ex

Then add your components:

defmodule PetalPro.Components.EmailComponents do
  use Phoenix.Component
  
  def my_new_component(assigns) do
    ~H"""
    Your component HTML goes here
    """
  end
end

Now it'll be available in your email templates!

<h1>Let's verify your account</h1>

<.my_new_component />

Landing page

<LandingPage.features
  title={gettext("Features")}
  description={gettext("Here are some features you can use to get started with your web app.")}
