#display
Sets the display behavior of the element.
          display: none;
        
The element is completely removed, as if it wasn't in the HTML code in the first place.
          display: inline;
        
The element is turned into an inline element: it behaves like simple text.
Any height and width applied will have no effect.
          display: block;
        
The element is turned into a block element: it starts on a new line, and takes up the whole width.
          display: inline-block;
        
The element shares properties of both an inline and a block element:
- inline because the element behaves like simple text, and inserts itself in a block of text
 - Block because you can apply 
heightandwidthvalues 
For example, this element has:
.element{
  height: 3em;
  width: 60px;
}
        
          display: list-item;
        
The element behaves like a list item: <li>. The only difference with block is that a list item has a bullet point.
          display: table;
        
The element behaves like a table: <table>.
Its content and child elements behave like table cells.
          display: table-cell;
        
The element behaves like a table cell: <td> or <th>.
Its content and child elements behave like table cells.
          display: table-row;
        
The element behaves like a table row: <tr>.
Its content and child elements behave like table cells.
          display: flex;
        
The element is turned into an flexbox container. On its own, it behaves like a block element.
Its child elements will be turned into flexbox items.
          display: inline-flex;
        
The element shares properties of both an inline and a flexbox element:
- inline because the element behaves like simple text, and inserts itself in a block of text
 - flexbox because its child element will be turned into flexbox items
 
For example, this element has:
.element{
  height: 3em;
  width: 120px;
}
