Any mkdocs-material syntax ignored in md files

[noeldum]

I am probably facing a simple problem but still need help for this.

Any mkdocs-material specific syntax that I include in my md files are ignored. i.e. They appear as just text in the rendered page.

Here is a dummy project setup to test this. I am on ubuntu.
mkdocs-material verion is 9.4.3
mkdocs version is 1.5.3
python version is 3.10.12

I just created a project
mkdocs new .

Edited the config:

site_name: My Docs
theme:
  name: material

Added something mkdocs-material specific in index.md. A button here.

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

Running this below seems ok.
mkdocs serve

Then my page looks like this

Any help appreciated. Am I missing something? It seems straight forward enough.

Hello,
for the { .md-button } syntax to work you need to enable the attr_list markdown extension, and the {} syntax is not exclusive for mkdocs-material, only the md-button class is directly related to it.

site_name: My Docs
theme:
  name: material
markdown_extensions:
  - attr_list
