    vertical-align

    Summary

    The vertical-align CSS property specifies the vertical alignment of an inline or table-cell box.

    • Initial value baseline
    • Applies to inline-level and table-cell elements
    • Inherited no
    • Percentages refer to the line-height of the element itself
    • Media visual
    • Computed value for percentage and length values, the absolute length, otherwise the keyword as specified
    • Animatable yes, as a length
    • Canonical order the unique non-ambiguous order defined by the formal grammar

    Syntax

    Formal syntax: baseline | sub | super | text-top | text-bottom | middle | top | bottom | <percentage> | <length>
    vertical-align: baseline     /* keyword values */
    vertical-align: sub
    vertical-align: super
    vertical-align: text-top
    vertical-align: text-bottom
    vertical-align: middle
    vertical-align: top
    vertical-align: bottom
    vertical-align: 10em          /* <length> values */
    vertical-align: 4px
    vertical-align: 20%           /* <percentage> values */
    
    vertical-align: inherit

    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 middle of lowercase letters in 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 (and sub, 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.

    Examples

    img {
    	vertical-align: bottom;
    }
