The begin attribute defines when the associated element becomes active. For an animation element, this is the point at which the animation should begin.

The <ellipse> SVG element is an SVG basic shape, used to create ellipses based on a center coordinate, and both their x and y radius.

The <style> SVG element allows style sheets to be embedded directly within SVG content.

The <path> SVG element is the generic element to define a shape. All the basic shapes can be created with a path element.

The alphabetic attribute defines the lower baseline of a font. It has the same syntax and semantics as the baseline descriptor within an @font-face.

The <stop> SVG element defines a color and its position to use on a gradient. This element is always a child of a <linearGradient> or <radialGradient> element.

The filter attribute specifies the filter effects defined by the <filter> element that shall be applied to its element.

The baseline-shift attribute allows repositioning of the dominant-baseline relative to the dominant-baseline of the parent text content element. The shifted object might be a sub- or superscript.

The <filter> SVG element defines a custom filter effect by grouping atomic filter primitives. It is never rendered itself, but must be used by the filter attribute on SVG elements, or the filter CSS property for SVG/HTML elements.

The direction attribute specifies the inline-base direction of a <text> or <tspan> element. It defines the start and end points of a line of text as used by the text-anchor and inline-size properties. It also may affect the direction in which characters are positioned if the unicode-bidi property's value is either embed or bidi-override.
