Transform centering

OSCC · CSS, Layout · Dec 30, 2020

Vertically and horizontally centers a child element within its parent element using CSS transforms.

  • Set the position of the parent to relative and that of the child to absolute to place it in relation to its parent.
  • Use left: 50% and top: 50% to offset the child 50% from the left and top edge of the containing block.
  • Use transform: translate(-50%, -50%) to negate its position, so that it is vertically and horizontally centered.
  • Note: The fixed height and width of the parent element is for demonstration purposes only.
