The display CSS property specifies the type of rendering box used for an element. In HTML, default display property values are taken from behaviors described in the HTML specifications or from the browser/user default stylesheet. The default value in XML is inline.
The empty-cells CSS property specifies how user agents should render borders and backgrounds around cells that have no visible content.
The flex CSS property is a shorthand property specifying the ability of a flex item to alter its dimensions to fill available space. Flex items can be stretched to use available space proportional to their flex grow factor or their flex shrink factor to prevent overflow.
The flex-direction CSS property specifies how flex items are placed in the flex container defining the main axis and the direction (normal or reversed).
The flex-flow CSS property is a shorthand property for flex-direction and flex-wrap individual properties.
The CSS flex-wrap property specifies whether flex items are forced into a single line or can be wrapped onto multiple lines. If wrapping is allowed, this property also enables you to control the direction in which lines are stacked.
The float CSS property specifies that an element should be taken from the normal flow and placed along the left or right side of its container, where text and inline elements will wrap around it.
The font CSS property is either a shorthand property for setting font-style, font-variant, font-weight, font-size, line-height and font-family, or a way to set the element's font to a system font, using specific keywords.
The font-family CSS property lets you specify a prioritized list of font family names and/or generic family names for the selected element. Values are separated by a comma to indicate that they are alternatives. The browser will select the first font on the list that is installed on the computer or that can be downloaded using a @font-face at-rule.
The font-feature-settings CSS property gives you control over advanced typographic features in OpenType fonts.
The font-language-override CSS property controls the usage of language-specific glyphs in a typeface.
The font-size CSS property specifies the size of the font (historically the width of the capital "M"). Setting the font size may, in turn, change the size of other items, since it is used to compute the value of the em and ex <length> units.
