Dimension.ex constructor

Dimension.ex(num _value)

Set this CSS Dimension to the specified number of x-heights.

One ex is equal to the x-height of a font's baseline to its mean line, generally the height of the letter "x" in the font, which is usually about half the font-size.

Implementation

Dimension.ex(this._value) : _unit = 'ex';
