Adding primary buttons

[everndah]

I want to add a button to a link in my landing page, but when trying to display a button using what has been provided in the documentation it does not turn into a button.

This is the line that I have added to my .md file

[Subscribe to our newsletter](#){ .md-button .md-button--primary }

The display on my landing page looks as shown in the image below.

What have I not done?

This looks like a lack of the markdown extension in the MkDocs.yml

markdown_extensions:
  - attr_list

[everndah]

there is a markdown extension in the mkdocs.yml.

Then something else is causing this issue, either bad formatting or some sort of other markdown extension is interfering with parsing of the attr_list. Here is a minimal example which is properly parsed on my end using the latest mkdocs-material version.
