CanvasRenderingContext2D.textAlign

by 2 contributors:

The CanvasRenderingContext2D.textAlign property of the Canvas 2D API specifies the current text alignment being used when drawing text. Beware that the alignment is base on the x value of the CanvasRenderingContext2D.fillText method. So if textAlign="center", then the text would be drawn at x-50%*width.

Syntax

ctx.textAlign = "left" || "right" || "center" || "start" || "end";

Options

Possible values:

left
The text is left-aligned.
right
The text is right-aligned.
center
The text is centered.
start
The text is aligned at the normal start of the line (left-aligned for left-to-right locales, right-aligned for right-to-left locales).
end
The text is aligned at the normal end of the line (right-aligned for left-to-right locales, left-aligned for right-to-left locales).

The default value is start.

Examples

Using the textAlign property

This is just a simple code snippet using the textAlign property to set a different text alignment.
