The HTMLLabelElement.htmlFor property reflects the value of the for content property.

The :empty selector refers only to child nodes, not input values. [value=""] does work; but only for the initial state. This is because a node's value attribute (that CSS sees), is not the same as the node's value property (Changed by the user or DOM javascript, and submitted as form data).

Types of Structure Outliners take advantage of what may be the most primitive of relationships, probably the first one you learned as an infant: in. Things can be in or contained by other things; alternatively, things can be superior to other things in a pecking order. Whatever the cognitive mechanics, trees/hierarchies are a preferred way of structuring things. But it is not the only way. Computer users also encounter: links, relationships, attributes, spatial/tabular arrangements, and metaphoric content. Links are what we know from the Web, but they can be so much more. The simplest ones are a sort of ad hoc spaghetti connecting pieces of text to text containers (like Web pages), but we will see many interesting kinds that have names, programs attached, and even work two-way. Relationships are what databases do, most easily imagined as “is-a” statements which are simple types of rules: Ted is a supervisor, supervisors are employees, all employees have employee numbers. Attributes are adjectives or tags that help characterize or locate things. Finder labels and playlists are good examples of these. Spatial/tabular arrangements are obvious: the very existence of the personal computer sprang from the power of the spreadsheet. Metaphors are a complex and powerful technique of inheriting structure from something familiar. The Mac desktop is a good example. Photoshop is another, where all the common tools had a darkroom tool or technique as their predecessor.

I'm looking at https://html.spec.whatwg.org/#attributes-3 right now, and it seems that there are a few others that ought to be boolean but are not currently in this list: allowpaymentrequest, formnovalidate, hidden (is on the original list in the master branch), itemscope, nomodule, and playsinline.

This is a boolean attribute: the presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value.

Svelte currently has no opinion as to what you store in an exported class prop of a component. It will not necessarily be used a class attribute.

Shorthand attributes It's not uncommon to have an attribute where the name and value are the same, like src={src}. Svelte gives us a convenient shorthand for these cases: <img {src} alt="A man dances.">

Refactoring is intended to improve the design, structure, and/or implementation of the software (its non-functional attributes), while preserving its functionality.

Hewson also identifies three properties of human beings that give rise to agency: intentionality, power, and rationality.

If you used browser JS DOM APIs (that have nothing to do with React itself), you know they don’t automatically update attributes

key attributes needed to produce a worthy PhD thesis are a readiness to accept failure; resilience; persistence; the ability to troubleshoot; dedication; independence; and a willingness to commit to very hard work — together with curiosity and a passion for research

"Element" SelectorsEach component has a data-reach-* attribute on the underlying DOM element that you can think of as the "element" for the component.

To support the extraction of themes, we refer to existent content analysis studies regardingTwitter, with a focus on theInformation-Community-Actionframework which is developed todescribe organization-public communication (Lovejoy and Saxton 2012).Informationtweetscontain factual information,community-buildingtweets reflect social engagement, andactiontweets are explicit calls for taking actions

Implications for practice

A system of relationships among the physical attributes is often shown to imitate or represent-by their configuration, content, and associations-conscious and unconscious aspects of social life.
