textBaseline property
The textBaseline property specifies
the vertical alignment of text drawn using the
fillText
or the
strokeText
methods. Takes one of the possible values:
top, hanging, middle,
alphabetic (default), ideographic,
bottom (see
www.w3schools.com/tags/canvas_textbaseline for meanings).asp).
Syntax
context.textBaseline = value;
Example
Let's set the text vertical alignment along the top line:
<canvas id="canvas" width="200" height="200" style="background: #f4f4f4;"></canvas>
const canvas = document.getElementById('canvas');
const ctx = canvas.getContext('2d');
ctx.strokeStyle = 'red';
ctx.moveTo(0, 100);
ctx.lineTo(400, 100);
ctx.stroke();
ctx.font="14px Arial";
ctx.textBaseline = 'top';
ctx.fillText('text', 80, 100);

Example
Now let's set the text vertical alignment along the bottom line:
<canvas id="canvas" width="200" height="200" style="background: #f4f4f4;"></canvas>
const canvas = document.getElementById('canvas');
const ctx = canvas.getContext('2d');
ctx.strokeStyle = 'red';
ctx.moveTo(0, 100);
ctx.lineTo(400, 100);
ctx.stroke();
ctx.font="14px Arial";
ctx.textBaseline="bottom";
ctx.fillText('text', 80, 100);
