link before accordion groups
Here is a simple accordion setup using the <details> element.

Requires a computer running an operating system. The computer must have some memory and ideally some kind of long-term storage. An input device as well as some form of output device is recommended.
Here is some content outside the accordion container.
Using <details> with a heading element inside
Hard disk capacity
Different size capacities of hard disk are available - from just a few gigabytes up to several terrabytes.
Also, it's perfectly possible to chain the hard disks together to increase capacity.
