translateY() - CSS: Cascading Style Sheets

The translateY() CSS function repositions an element vertically on the 2D plane. Its result is a <transform-function> data type.

Note: translateY(ty) is equivalent to translate(0, ty) or translate3d(0, ty, 0).

Syntax

/* <length-percentage> values */
transform: translateY(200px);
transform: translateY(50%);

<length-percentage>: The value is a <length> or <percentage> representing the ordinate of the translating vector. A percentage value refers to the height of the reference box defined by the transform-box property.

A translation is not a linear transformation in ℝ² and can't be represented using a Cartesian-coordinate matrix.	$(\begin{matrix} 1 & 0 & 0 \\ 0 & 1 & t \\ 0 & 0 & 1 \end{matrix})$	$(\begin{matrix} 1 & 0 & 0 \\ 0 & 1 & t \\ 0 & 0 & 1 \end{matrix})$	$(\begin{matrix} 1 & 0 & 0 & 0 \\ 0 & 1 & 0 & t \\ 0 & 0 & 1 & 0 \\ 0 & 0 & 0 & 1 \end{matrix})$
