Using Display Visibility Property
  • Display property specifies the type of box used
    for an HTML element.
  • Syntax for displaying ltpgt elements as inline

  • Visibility property specifies whether or not an

Overlapping of Elements
  • Overlapping of elements situation arises when one
    element positioning is fixed.
  • Negative margin  pull the element over another or
    Absolutely positioned elements overlap each
  • Uses z-index property to overcome the situation.
  • By default, elements are stacked by their
    position in the HTML code. Z property allows to
    specify where elements have to be placed.
