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.

<div class="parent">
  <div class="child">Centered content</div>
