Is letter spacing supported in Spark Label?

Question

I can't seem to adjust the letter and character spacing in the Spark Label. I've tried setting the tracking left and right and the letter spacing. Is it supported?

Answer 1

use css(style) for that

.lbl
{
    letterSpacing: 1;
}

Answer 2

Use trackingLeft (The amount of tracking (manual kerning) to be applied to the left of each character) or trackingRight (The amount of tracking (manual kerning) to be applied to the right of each character).
For the Spark theme, letterSpacing is not supported.
