The font-style attribute specifies whether the text is to be rendered using a normal, italic, or oblique face.

Traits, helpers, and type definitions for core I/O functionality.

This chapter introduces the two most fundamental data types in JavaScript: numbers and strings. We will introduce their underlying representations, and functions used to work with and perform calculations on them.

The markerWidth attribute represents the width of the viewport into which the <marker> is to be fitted when it is rendered according to the viewBox and preserveAspectRatio attributes.

The height attribute defines the vertical length of an element in the user coordinate system.

The new operator lets developers create an instance of a user-defined object type or of one of the built-in object types that has a constructor function.

The cursor attribute specifies the mouse cursor displayed when the mouse pointer is over an element.

The AsyncDisposableStack object represents a stack of async disposers to run when the stack itself is disposed. Disposer functions are executed in reverse order of registration, with strong error handling guarantees. Calling its move() method will transfer responsibility for calling the current registered disposers to a new AsyncDisposableStack and prevent registering any additional disposers.

The <marker> SVG element defines a graphic used for drawing arrowheads or polymarkers on a given <path>, <line>, <polyline> or <polygon> element.

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