vertical-align - CSS: Cascading Style Sheets

vertical-align

Baseline Widely available

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

vertical-align: baseline;

vertical-align: text-top;

<section class="default-example" id="default-example">
  <p>
    Align the star:
    <img id="example-element" src="/shared-assets/images/examples/star2.png" />
  </p>
</section>

#default-example > p {
  line-height: 3em;
  font-family: monospace;
  font-size: 1.2em;
  text-decoration: underline overline;
}

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-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.

Values for table cells

baseline (and sub, 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.

Result Vertical alignment in a table cell

In this example, we have a table with a single row containing six cells. The row sets vertical-align to bottom as the default value.

The first four cells each set their own vertical-align values, and these override the row's value.
The fifth cell does not set any vertical-align value, so inherits the row's value.

The sixth cell is only used to ensure that the cells are tall enough to see the effect.
