How are Dropdowns used in CSS?

Dropdowns are one of the most important parts of an interactive website. CSS is used to design the drop-down menus. A drop-down is a bunch of lists under an unordered list i.e. <ul> as it is popularly known in the HTML world. Nested list (<li>) tags under the <ul> tag are used to create a drop-down structure. To bring out the effects use CSS for the components present in the structure.

CSS is a very straightforward property used to create the drop-down menu.

  • Basic Dropdown: Create a dropdown box that appears when the user moves the mouse over an element.
  • Right-aligned Dropdown Content: If you want the dropdown menu to go from right to left, instead of left to right, add right: 0;
