Valores (para elementos en línea)
La mayoría de los valores de alinean verticalmente el elemento de forma relativa al elemento padre:
baselineAlinea la línea base del elemento con la línea base del padre. La línea base de algunoselementos reemplazados, como
<textarea>no está especificado en la especificación HTML, que significa que su comportamiento puede cambiar en un navegador u otro.subAlinea la línea base del elemento con la línea subscript del elemento padre.
superAlinea la línea base del elemento con la línea superscript del elemento padre.
text-topAligns the top of the element with the top of the parent element's font.
text-bottomAligns the bottom of the element with the bottom of the parent element's font.
middleAligns the middle of the element with the middle of lowercase letters in the parent.
<length>Aligns the baseline of the element at the given length above the baseline of its parent.
<percentage>Like <length> values, with the percentage being a percent of the
line-heightproperty.For elements that do not have a baseline, the bottom margin edge is used instead.
However, two values vertically align the element relative to the entire line rather than relative to its parent:
topAlign the top of the element and its descendants with the top of the entire line.
bottomAlign the bottom of the element and its descendants with the bottom of the entire line.
Negative values are allowed.
