Reference to specification
It aligns an element on a vertical concerning the parent or the surrounding text.


vertical-align: baseline | bottom | middle | sub | super | text-bottom | text-top | top | value | percent
It aligns a base line of a current element on a parent base line. If the parental element has no base line, the bottom border of an element is accepted instead of it.
It aligns the basis of a current element by the bottom part of a line element located below of all.
It aligns an average element point on a base line of the parent plus a half of height of a parental element.
The element is indicated as interlinear one in the form of the bottom index. The font size thus does not vary.
The element is indicated as superior in the form of the top index. The font size remains former.
The bottom border of an element is aligned on the lowermost border of the current line.
The top border of an element is aligned on the highest text element of the current line.
It aligns an upper border of an element on the highest element top of a line.
It is possible to use as value percent, percent or other accessible units. The positive argument displaces an element upwards concerning a base line while negative value lowers it downwards. Not all browsers support such way of record, in particular Internet Explorer supports it only from the sixth version.
