Valores (para elementos en línea)
La mayoría de los valores de alinean verticalmente el elemento de forma relativa al elemento padre:
baseline-
Alinea la línea base del elemento con la línea base del padre. La línea base de algunos elementos reemplazados, como
<textarea>no está especificado en la especificación HTML, que significa que su comportamiento puede cambiar en un navegador u otro. sub-
Alinea la línea base del elemento con la línea subscript del elemento padre.
super-
Alinea la línea base del elemento con la línea superscript del elemento padre.
text-top-
Aligns the top of the element with the top of the parent element's font.
text-bottom-
Aligns the bottom of the element with the bottom of the parent element's font.
middle-
Aligns 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:
top-
Align the top of the element and its descendants with the top of the entire line.
bottom-
Align the bottom of the element and its descendants with the bottom of the entire line.
Negative values are allowed.

middle-
Center the padding box of the cell within the row.
