The SVG styling attributes are all the attributes that can be specified on any SVG element to apply CSS styling effects.

The addition assignment (+=) operator performs addition (which is either numeric addition or string concatenation) on the two operands and assigns the result to the left operand.

The SVG <animateMotion> element provides a way to define how an element moves along a motion path.

The conditional (ternary) operator is the only JavaScript operator that takes three operands: a condition followed by a question mark (?), then an expression to execute if the condition is truthy followed by a colon (:), and finally the expression to execute if the condition is falsy. This operator is frequently used as an alternative to an if...else statement.

The <feDisplacementMap> SVG filter primitive uses the pixel values from the image from in2 to spatially displace the image from in.

The <feDistantLight> filter primitive defines a distant light source that can be used within a lighting filter primitive: <feDiffuseLighting> or <feSpecularLighting>.

The by attribute specifies a relative offset value for an attribute that will be modified during an animation.

The dominant-baseline attribute specifies the dominant baseline, which is the baseline used to align the box's text and inline-level contents. It also indicates the default alignment baseline of any boxes participating in baseline alignment in the box's alignment context.

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

The <use> element takes nodes from within the SVG document, and duplicates them somewhere else. The effect is the same as if the nodes were deeply cloned into a non-exposed DOM, then pasted where the use element is, much like cloned template elements.
