A character class matches any character in or not in a custom set of characters. When the v flag is enabled, it can also be used to match finite-length strings.

Assigns a class name or set of class names to an element. You may assign the same class name or names to any number of elements, however, multiple class names must be separated by whitespace characters.

The <feMorphology> SVG filter primitive is used to erode or dilate the input image. Its usefulness lies especially in fattening or thinning effects.

The <metadata> SVG element adds metadata to SVG content. Metadata is structured information about data. The contents of <metadata> should be elements from other XML namespaces such as RDF, FOAF, etc.

The <view> SVG element defines a particular view of an SVG document. A specific view can be displayed by referencing the <view> element's id as the target fragment of a URL.

The <tspan> SVG element defines a subtext within a <text> element or another <tspan> element. It allows for adjustment of the style and/or position of that subtext as needed.

The bias attribute shifts the range of the filter. After applying the kernelMatrix of the <feConvolveMatrix> element to the input image to yield a number and applied the divisor attribute, the bias attribute is added to each component. This allows representation of values that would otherwise be clamped to 0 or 1.

The JavaScript exception "TypeError: matchAll/replaceAll must be called with a global RegExp" occurs when the String.prototype.matchAll() or String.prototype.replaceAll() method is used with a RegExp object that does not have the global flag set.

This page introduces the basic infrastructure of the JavaScript runtime environment. The model is largely theoretical and abstract, without any platform-specific or implementation-specific details. Modern JavaScript engines heavily optimize the described semantics.
