How to create a Hidden Header using Google AMP Amp-Accordion?

Google AMP (Accelerated Mobile Pages) is an open−source framework designed to create fast−loading and mobile−friendly web pages, while amp−accordion is a component in the AMP library that allows for collapsible content sections on a web page. Google offers the Accelerated Mobile Pages (AMP) framework allowing you to make hidden content that the user can toggle open and closed.


  • Declare a new HTML5 document using the declaration at the beginning of the file.

  • Inside the element, add the ⚡ attribute to indicate that this is an AMP HTML document.

  • Inside the element, add the meta element with the charset attribute set to "utf−8".

  • Set the document title using the title element.

  • Add a link element with the rel attribute set to "canonical" and the href attribute set to the canonical URL of the document.

  • Add a meta element with the name attribute set to "viewport", and the content attribute set to "width=device−width,minimum−scale=1,initial−scale=1". This sets the viewport width to the width of the device and sets the initial scale to 1.

  • Add a script element with the src attribute set to "" to reference the AMP JavaScript library. Use the async attribute to load the script asynchronously.

  • Add a style element with the amp−custom attribute to define custom CSS styles for the document. This is where you would add any custom styles that you want to use with AMP.

  • Inside the element, add the visible content of the document.

  • Use the <amp−accordian> element to create an accordion. Add one or more <section> elements inside the <amp−accordian> element. Each <section> should include a header (<h2>) and content (<div>).

  • Save the document with a .html file extension and open it in a web browser to view the results.
