Animating the content attribute

In most browsers this is just going to show the letter 'A' but in the latest version of Chrome it should animate between 'A' and 'B'.

Not sure how useful this might be in the future, but it seems pretty cool!

 * To include the nodes only when a particular media query matches, use the attributes

State switching in HTML

HTML is where mature JavaScript patterns graduate to, removing the need for scripting for common, well-established user interactions. Having a button switch some state on click is a common pattern that needs to move into a declarative HTML-only setup.

Problem statement:

Button-type buttons (<button type="button"></button>) have no inherent behavior. Currently, they require scripting to do anything. A common behavior added is to switch some state:

• Menu button toggles the state of a menu between "open" and "closed"
• Toggle button switches a site setting, e.g. between "dark mode," "light mode," and "match OS"/"auto"
• Tab/accordion button switches the state of the tabset or accordion to one particular section (alternatively, it sets the state for the designated section to "active/open/visible" and the states for all other sections to "inactive/closed/hidden")
