# Create block templates

Head back to your templates directory and create a new directory named blocks. Inside that directory, create a new file called text.twig and paste the following code.

templates/blocks/text.twig

label: Text block
icon: material:format_align_left
preview: >
  {{ body.snippet }}
fields:
  body:
    type: redactor
---
<div class="container">
  {{ body.html }}
</div>

There are two new attributes in the Yaml block:

• The icon attribute defines an icon for the template type in order to make blocks easier to distinguish in the control panel. A list of all available icons can be found in the control panel Utilities > Content field utilities.

• The preview attribute contains a simple preview of the block that will be shown to the editor in the control panel. It's a handlebars template that has access to all fields defined in the current template.

Next create a new file called image.twig in the same directory and paste the following code.

templates/blocks/image.twig

label: Image block
icon: material:picture
preview: >
  {{ image }}
fields:
  image:
    type: image
    rules: required
---
<div class="container">
  <img src="{{ image.first.url }}" />
</div>

The image field type is a field that allows editors to select assets. Note the rule attribute on the image field, it marks the field as being required.
