vertical-align
The vertical-align
CSS property sets vertical alignment of an inline, inline-block or table-cell box.
Try it
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.

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-height
property. 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.
