<section id="default-example">
  <img

    id="static-element"
    src="/shared-assets/images/examples/firefox-logo.svg"
    width="200" />
  <img

Syntax

css

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

Values

<length-percentage>

The value is a <length> or <percentage> representing the ordinate (vertical, y-coordinate) of the translating vector [0, ty]. In Cartesian coordinate system it represents shift along y-axis. 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 ℝ^2 and can't be represented using a Cartesian-coordinate matrix.

(10001t001)\left( \begin{array}{ccc} 1 & 0 & 0 \\ 0 & 1 & t \\ 0 & 0 & 1 \end{array} \right)
(10001t001)\left( \begin{array}{ccc} 1 & 0 & 0 \\ 0 & 1 & t \\ 0 & 0 & 1 \end{array} \right)
(1000010t00100001)\left( \begin{array}{cccc} 1 & 0 & 0 & 0 \\ 0 & 1 & 0 & t \\ 0 & 0 & 1 & 0 \\ 0 & 0 & 0 & 1 \end{array} \right)
[1 0 0 1 0 t]
