1. CSS display: contents

    `display: contents` causes an element's children to appear as if they were direct children of the element's parent, ignoring the element itself. This can be useful when a wrapper element should be ignored when using CSS grid or similar layout techniques.

  2. CSS font-stretch

    If a font has multiple types of variations based on the width of characters, this property allows the appropriate one to be selected. The property in itself does not cause the browser to stretch to a font. Note that `font-stretch` is an alias of the [`font-width`](/wf-font-width) CSS property.

  3. CSS Grid Layout (level 1)

    Method of using a grid concept to lay out content, providing a mechanism for authors to divide available space for layout into columns and rows using a set of predictable sizing behaviors. Includes support for all `grid-*` properties and the `fr` unit.

  4. CSS if() function

    The `if()` CSS function allows different values to be set for a property depending on the result of a conditional test. The test can be based on a style query, a media query, or a feature query.

  5. CSS initial value

    A CSS value that will apply a property's initial value as defined in the CSS specification that defines the property

  6. CSS Paged Media (@page)

    CSS at-rule (`@page`) to define page-specific rules when printing web pages, such as margin per page and page dimensions.

  7. CSS revert value

    A CSS keyword value that resets a property's value to the default specified by the browser in its UA stylesheet, as if the webpage had not included any CSS. For example, `display:revert` on a `<div>` would result in `display:block`. This is in contrast to the `initial` value, which is simply defined on a per-property basis, and for `display` would be `inline`.

  8. CSS Scroll-behavior

    Method of specifying the scrolling behavior for a scrolling box, when scrolling happens due to navigation or CSSOM scrolling APIs.

  9. CSS.supports() API

    The CSS.supports() static method returns a Boolean value indicating if the browser supports a given CSS feature, or not.

  10. CSS3 text-align-last

    CSS property to describe how the last line of a block or a line right before a forced line break when `text-align` is `justify`.

  11. CSS Text Box

    CSS `text-box` (and its longhands `text-box-trim` & `text-box-edge`) provide the ability to trim extra space over/under text glyphs at the start/end of a block to match specific font-provided metrics. This allows for more precise alignment and positioning of text.

  12. CSS text-justify

    CSS property to define how text should be justified when `text-align: justify` is set.

  13. CSS text-orientation

    The CSS `text-orientation` property specifies the orientation of text within a line. Current values only have an effect in vertical typographic modes (defined with the `writing-mode` property)

  14. CSS unset value

    A CSS value that's the same as "inherit" if a property is inherited or "initial" if a property is not inherited.

  15. CSS Flexible Box Layout Module

    Method of positioning elements in horizontal or vertical stacks. Support includes all properties prefixed with `flex`, as well as `display: flex`, `display: inline-flex`, `align-content`, `align-items`, `align-self`, `justify-content` and `order`.

  16. CSS justify-content: space-evenly

    The "space-evenly" value for the `justify-content` property distributes the space between items evenly. It is similar to space-around but provides equal instead of half-sized space on the edges. Can be used in both CSS flexbox & grid.

  17. CSS text-size-adjust

    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.

  18. CSS3 Overflow-wrap

    Allows lines to be broken within words if an otherwise unbreakable string is too long to fit. Currently mostly supported using the `word-wrap` property.
