This is a simple snippet using HTML tags. Though it looks like an accordion it is much more. It is a plain HTML details tag which specifies the additional details that the user can use and hide on demand. Unlink accordion, it is not collapsible unless it is clicked. This snippet can be used on any website to show the small amount of information for a particular section. Take a look at CSS, each tag is styled. The hovering function is used for the summary, once you hover the mouse on summary the styling is set for the borders of summary tag, along with the colours set for the details and summary in open state. The styling would enhance these simple tags and gives it look as collapsible or accordion. This can be used in your website easily to enhance your paragraphs.
This snippet shows examples of Accordion and toggles using Velocity.js. Velocity.js is an animation engine for the UI, which works with or without JQuery. It is fast it features colour animation, transforms, loops, easings, SVG support, and scrolling. It can be used instead of Jquery and CSS. Here, the snippet deals with bootstrap 3 combined with Velocity.js v1.2. You can see the Accordion and Toggle behaviour created using bootstrap classes. The HTML is similar for both the example, take a look at the CSS and JQuery. Jquery uses the Velocity for creating the animation effect for fading the panels once clicked to see the accordion and toggling behaviour. The animations are smoothly done. This would be used in websites with large content. You can use this code with your personal tweak to blend with your page.
