On XML, the xml:lang attribute must be used.

The image-rendering CSS property provides a hint to the user agent about how to handle its image rendering. It applies to any images appearing on the element properties, but has no effect on non-scaled images.. For example, if the natural size of the image is 100×100px but the page author specifies the dimensions to 200×200px (or 50×50px), then the image will be upscaled (or downscaled) to the new dimensions using the specified algorithm. Scaling may also apply due to user interaction (zooming).

The page-break-before CSS property adjusts page breaks before the current element.

The page-break-inside CSS property adjusts page breaks inside the current element.

The perspective CSS property determines the distance between the z=0 plane and the user in order to give to the 3D-positioned element some perspective. Each 3D element with z>0 becomes larger; each 3D-element with z<0 becomes smaller. The strength of the effect is determined by the value of this property.

The place-self CSS property is a shorthand property sets both the align-self and justify-self properties. The first value is the align-self property value, the second the justify-self one. If the second value is not present, the first value is also used for it.

The CSS property pointer-events allows authors to control under what circumstances (if any) a particular graphic element can become the target of mouse events. When this property is unspecified, the same characteristics of the visiblePainted value apply to SVG content.

The scroll-behavior CSS property specifies the scrolling behavior for a scrolling box, when scrolling happens due to navigation or CSSOM scrolling APIs. Any other scrolls, e.g. those that are performed by the user, are not affected by this property. When this property is specified on the root element, it applies to the viewport instead.

The shape-image-threshold CSS property defines the alpha channel threshold used to extract the shape using an image as the value for shape-outside. A value of 0.5 means that the shape will enclose all the pixels that are more than 50% opaque.

The shape-margin CSS property adds a margin to shape-outside.

This attribute specifies the opacity of the color or the content the current object is filled with.

The text-align CSS property describes how inline content like text is aligned in its parent block element. text-align does not control the alignment of block elements itself, only their inline content.

The text-align-last CSS property describes how the last line of a block or a line, right before a forced line break, is aligned.

The text-decoration-color CSS property sets the color used when drawing underlines, overlines, or strike-throughs specified by text-decoration-line. This is the preferred way to color these text decorations, rather than using combinations of other HTML elements.

The text-decoration-line CSS property sets what kind of line decorations are added to an element.

The text-decoration-style CSS property defines the style of the lines specified by text-decoration-line. The style applies to all lines, there is no way to define different style for each of the line defined by text-decoration-line.

The text-indent CSS property specifies how much horizontal space should be left before the beginning of the first line of the text content of an element. Horizontal spacing is with respect to the left (or right, for right-to-left layout) edge of the containing block element's box.

The text-orientation CSS property defines the orientation of the text in a line. This property only has an effect in vertical mode, that is when writing-mode is not horizontal-tb. It is useful to control the display of writing in languages using vertical script, but also to deal with vertical table headers.

On mobile devices, the text-size-adjust CSS property allows Web authors to control if and how the text-inflating algorithm is applied to the textual content of the element it is applied to.

The text-transform CSS property specifies how to capitalize an element's text. It can be used to make text appear in all-uppercase or all-lowercase, or with each word capitalized.

The CSS transition-timing-function property is used to describe how the intermediate values of the CSS properties being affected by a transition effect are calculated. This in essence lets you establish an acceleration curve, so that the speed of the transition can vary over its duration.

The unicode-bidi CSS property together with the direction property relates to the handling of bidirectional text in a document. For example, if a block of text contains both left-to-right and right-to-left text then the user-agent uses a complex Unicode algorithm to decide how to display the text. This property overrides this algorithm and allows the developer to control the text embedding.

The visibility CSS property has two purposes:

The white-space CSS property is used to to describe how white spaces inside the element is handled.

The background-blend-mode CSS property describes how the element's background images should blend with each other and the element's background color.

The CSS background-image property sets one or several background images for an element. The images are drawn on stacking context layers on top of each other. The first layer specified is drawn as if it is closest to the user. The borders of the element are then drawn on top of them, and the background-color is drawn beneath them.

The border-image-repeat CSS property defines how the middle part of a border image is handled so that it can match the size of the border. It has a one-value syntax that describes the behavior of all the sides, and a two-value syntax that sets a different value for the horizontal and vertical behavior.

The border-image-slice CSS property divides the image specified by border-image-source in nine regions: the four corners, the four edges and the middle. It does this by specifying 4 inwards offsets.

The border-image-source CSS property defines the <image> to use instead of the style of the border. If this property is set to none, the style defined by border-style is used instead.

The border-image-width CSS property defines the width of the border. If specified, it overrides the border-width property.

The -webkit-box-reflect CSS property lets you reflect the content of an element in one specific direction.

Note: This feature is not intended to be used by Web sites. To achieve reflection on the Web, the standard way is to use the CSS element() function.

The CSS flex-basis property specifies the flex basis which is the initial main size of a flex item. The property determines the size of the content-box unless specified otherwise using box-sizing.

The CSS flex-flow property is a shorthand property for flex-direction and flex-wrap individual properties.

Flows content from a named flow (specified by a corresponding flow-into) through selected elements to form a dynamic chain of layout regions.

Diverts the selected element's content into a named flow, used to thread content through different layout regions specified by flow-from.

The font-language-override CSS property controls the usage of language-specific glyphs in a typeface.

The font-synthesis CSS property controls which missing typefaces, bold or italic, may be synthesized by the browser.

The font-variant CSS property selects a normal, or small-caps face from a font family. Setting the CSS Level 2 (Revision 1) values of the font-variant property, that is normal or small-caps, is also possible by using the font shorthand.

The font-variant-alternates CSS property controls the usage of alternate glyphs associated to alternative names defined in @font-feature-values.

The font-variant-east-asian CSS property controls the usage of alternate glyphs for East Asian scripts, like Japanese and Chinese.

The font-variant-ligatures CSS property controls which ligatures and contextual forms are used in textual content of the elements it applies to. This leads to more harmonized forms in the resulting text.

The font-variant-numeric CSS property controls the usage of alternate glyphs for numbers, fractions, and ordinal markers.

This property provides low-level control over OpenType or TrueType font variations. It is intended as a way of providing access to font variations that are not widely used but are needed for a particular use case.
