Creating SNS Topics

To create an Amazon SNS topic, follow these steps:

  1. Sign in to the AWS Management Console:
    • Go to the AWS Management Console and sign in with your AWS account credentials.
    • Navigate to the Amazon SNS dashboard.
  2. Create a Topic:
    • Click on Topics in the navigation panel.
    • Click on Create topic.
    • Choose the topic type:
      • Standard: This is the default topic type and supports multiple subscriber types.
      • FIFO (First-In-First-Out): This topic type ensures that messages are processed in the order they are received.
  3. Configure the Topic:
    • Enter a Name for the topic. For a FIFO topic, add .fifo to the end of the name.
    • Optionally, enter a Display name for the topic.
    • For a FIFO topic, you can choose Content-based message deduplication to enable default message deduplication.
    • Expand the Encryption section and choose Enable encryption to specify the AWS KMS key.
  4. Create the Topic:
    • Click Create topic to create the topic.

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
