The vertical-align CSS property sets vertical alignment of an inline, inline-block or table-cell box.
The vertical-align property can be used in two contexts:
- To vertically align an inline-level element's box inside its containing line box. For example, it could be used to vertically position an image in a line of text.
- To vertically align the content of a cell in a table.
Note that vertical-align only applies to inline, inline-block and table-cell elements: you can't use it to vertically align block-level elements.
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: revert; vertical-align: revert-layer; vertical-align: unset;
The vertical-align property is specified as one of the values listed below.
Values for inline elements
Parent-relative values
These 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 vary between browsers. 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 to the given length above the baseline of its parent. A negative value is allowed.
<percentage>-
Aligns the baseline of the element to the given percentage above the baseline of its parent, with the value being a percentage of the
line-heightproperty. A negative value is allowed.
Line-relative values
The following values vertically align the element relative to the entire line:
top-
Aligns the top of the element and its descendants with the top of the entire line.
bottom-
Aligns 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>)-
Aligns the baseline of the cell with the baseline of all other cells in the row that are baseline-aligned.
top-
Aligns the top padding edge of the cell with the top of the row.
middle-
Centers the padding box of the cell within the row.
bottom-
Aligns the bottom padding edge of the cell with the bottom of the row.
Negative values are allowed.
