The decodeURI() function decodes a Uniform Resource Identifier (URI) previously created by encodeURI() or a similar routine.

The encodeURIComponent() function encodes a URI by replacing each instance of certain characters by one, two, three, or four escape sequences representing the UTF-8 encoding of the character (will only be four escape sequences for characters composed of two surrogate characters). Compared to encodeURI(), this function encodes more characters, including those that are part of the URI syntax.

The <feColorMatrix> SVG filter element changes colors based on a transformation matrix. Every pixel's color value [R,G,B,A] is matrix multiplied by a 5 by 5 color matrix to create new color [R',G',B',A'].

The <feFuncB> SVG filter primitive defines the transfer function for the blue component of the input graphic of its parent <feComponentTransfer> element.

The font-size attribute refers to the size of the font from baseline to baseline when multiple lines of text are set solid in a multiline layout environment.

The async function* keywords can be used to define an async generator function inside an expression.

The <font-face-name> SVG element points to a locally installed copy of this font, identified by its name.

The clipPathUnits attribute indicates which coordinate system to use for the contents of the <clipPath> element.

The fy attribute defines the y-axis coordinate of the focal point for a radial gradient.

The end attribute defines an end value for the animation that can constrain the active duration.
