This attribute indicates a vertical length in the user coordinate system. The exact effect of this coordinate depends on each element. Most of the time, it represents the height of the rectangular region of the reference element (see each individual element's documentation for exceptions).
This attribute must be specified except for the <svg>
element where the default value is 100% and the <filter>
and <mask>
elements where the default value is 120%.
