The unicode-bidi CSS property, together with the direction property, determines how bidirectional text in a document is handled. For example, if a block of content contains both left-to-right and right-to-left text, the user-agent uses a complex Unicode algorithm to decide how to display the text. The unicode-bidi property overrides this algorithm and allows the developer to control the text embedding.
The user-select CSS property controls whether the user can select text. This doesn't have any effect on content loaded as part of a browser's user interface (its chrome), except in textboxes.
The vertical-align CSS property sets vertical alignment of an inline, inline-block or table-cell box.
The view-timeline-axis CSS property is used to specify the scrollbar direction that will be used to provide the timeline for a named view progress timeline animation, which is progressed through based on the change in visibility of an element (known as the subject) inside a scrollable element (scroller). view-timeline-axis is set on the subject. See CSS scroll-driven animations for more details.
The view-timeline-inset CSS property is used to specify one or two values representing an adjustment to the position of the scrollport (see Scroll container for more details) in which the subject element of a named view progress timeline animation is deemed to be visible. Put another way, this allows you to specify start and/or end inset (or outset) values that offset the position of the timeline.
The view-timeline-name CSS property is used to define the name of a named view progress timeline, which is progressed through based on the change in visibility of an element (known as the subject) inside a scrollable element (scroller). view-timeline is set on the subject.
The view-transition-name CSS property provides the selected element with a distinct identifying name (a <custom-ident>) and causes it to participate in a separate view transition from the root view transition — or no view transition if the none value is specified.
The visibility CSS property shows or hides an element without changing the layout of a document. The property can also hide rows or columns in a <table>.
The white-space CSS property sets how white space inside an element is handled.
The white-space-collapse CSS property controls how white space inside an element is collapsed.
Syntax: none | discard-before || discard-after || discard-inner

The word-spacing CSS property sets the length of space between words and between tags.
The writing-mode CSS property sets whether lines of text are laid out horizontally or vertically, as well as the direction in which blocks progress. When set for an entire document, it should be set on the root element (html element for HTML documents).
