The vertical-align property is used in CSS and certain HTML elements. It specifies the vertical alignment of an inline or table-cell element.

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.
• 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. Ex. px, em, etc.
• <percentage> - Like <length> values, with the percentage being a percent of the line-height property.

For elements that do not have a baseline, the bottom margin edge is used instead. However, two values vertically align the element relative to the entire line rather than relative to its parent.

• 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.

Negative values are allowed for all values.

Values for table-cell elements

• baseline, sub, super, text-top, text-bottom, <length>, or <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 for all values.

<img style="vertical-align:bottom;" src="Image1.png" />
