我已创建一个自定义的Jekyll液体标签
```ruby
# my_tag.rb
module Jekyll
    class MyTag < Liquid::Tag
      def initialize(tag_name, markup, tokens)
        super
        @title = markup['title']
        @step = markup['step']
      end
      def render(context)
        output = "<div>"
        output += "<h1>#{@title} #{@step}</h1>"
        output += "<p>#{super}</p>"
        output += "</div>"
        output
      end
    end
end
Liquid::Template.register_tag('my_tag', Jekyll::MyTag)

{% my_tag title="hello" step="world" %}
This is the data
{% endmy_tag %}

I have created a following custom Jekyll liquid tag

  def render(context)
    output = "<div>"
    output += "<h1>#{@title} #{@step}</h1>"
    output += "<p>#{super}</p>"
    output += "</div>"
    output
  end
end

And I'm using it in following way in a markdown post
```markdown
{% my_tag title="hello" step="world" %}
This is the data
{% endmy_tag %}
