Syntax
/* keyword values */ vertical-align: baseline; vertical-align: sub; vertical-align: super; vertical-align: text-top; vertical-align: text-bottom; vertical-align: middle; vertical-align: top; vertical-align: bottom; /* <length> values */ vertical-align: 10em; vertical-align: 4px; /* <percentage> values */ vertical-align: 20%; /* Global values */ vertical-align: inherit; vertical-align: initial; vertical-align: unset;
Values (for inline elements)
Most of the values vertically align the element relative to its parent element:
baseline
- Aligns the baseline of the element with the baseline of its parent. The baseline of some replaced elements, like
<textarea>
, is not specified by the HTML specification, meaning that their behavior with this keyword may change from one browser to the other. sub
- Aligns the baseline of the element with the subscript-baseline of its parent.
super
- Aligns the baseline of the element with the superscript-baseline of its parent.
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 baseline plus half the x-height of 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-height
property.
(Negative values are allowed for <length> and <percentage>.)
The following 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.
For elements that do not have a baseline, the bottom margin edge is used instead.
Values (for table cells)
baseline
(andsub
,super
,text-top
,text-bottom
,<length>
, and<percentage>
)- Align the baseline of the cell with the baseline of all other cells in the row that are baseline-aligned.
top
- Align the top padding edge of the cell with the top of the row.
middle
- Center the padding box of the cell within the row.
bottom
- Align the bottom padding edge of the cell with the bottom of the row.
Negative values are allowed.
