HTML and CSS Reference
In-Depth Information
For our demonstration, instead of trying to use the font size to vertically center the text on the
canvas, we will create the
yPosition
variable for the text by simply placing it at one-half the
height of the canvas. The default
baseline
for a font is
middle
, so this works great for cen-
tering on the screen. We will talk more about
baseline
in the next section:
var
var
yPosition
=
(
theCanvas
.
height
/
2
);
NOTE
In the chat example in
Chapter 11
, we will show you an example of breaking up text onto multiple
lines.
