HTML and CSS Reference
Align the bottom of the element with the bottom of the lowest ele-
ment in the current line.
In addition, a percentage value indicates a position relative to the cur-
rent baseline so that a position of 50% puts the element halfway up the
line height above the baseline. A position value of -100% puts the ele-
ment an entire line height below the baseline of the current line.
All the popular browsers agree on where to place images relative to a
line of text for baseline (default and the same as no vertical-align spe-
cification), middle (but not center), super (but not sub ), text-top, text-
bottom, top (same as text-top ; but not bottom ), and for both plus and
minus percentage offset values. Figure 8-10 shows you how Internet
Explorer treats the various vertical-align values.
