Steps

1. Create a new component on this page by duplicating or creating a new 'component_item' below
2. Create a new unique identifier for this and update the attribute to reflect it. Update the yellow tag as well to keep this more managable
3. Once the component is created and we have an identifier, go to the blog post rich text field you want to use this component in and reference it inside the RTF by using the syntax: {{COMPONENT_IDENTIFIER="/components"}}. For example, if you have a component with identifier 'test-cta', then you would add {{test-cta="/components"}} to the RTF

🚨 Note: this only works with HTML & CSS [no javascript]
