Definition and Usage
The display property sets or returns the element’s display type.
Elements in HTML are mostly «inline» or «block» elements: An inline element
has floating content on its left and right side. A block element fills the
entire line, and nothing can be displayed on its left or right side.
The display property also allows the author to show or hide an element. It is
similar to the visibility property. However, if you set , it hides
the entire element, while means that the contents of the
element will be invisible, but the element stays in its original position and
size.
Tip: If an element is a block element, its display type can also be
changed with the float property.
More Examples
Difference between the display property and the visibility property:
function demoDisplay() { document.getElementById(«myP1»).style.display = «none»;
}function demoVisibility() { document.getElementById(«myP2»).style.visibility = «hidden»;
}
Toggle between hiding and showing an element:
function myFunction() { var x = document.getElementById(‘myDIV’); if (x.style.display === ‘none’) {
x.style.display = ‘block’; } else { x.style.display = ‘none’;
}}
Difference between «inline», «block» and «none»:
function myFunction(x) { var whichSelected = x.selectedIndex; var sel = x.options.text;
var elem = document.getElementById(«mySpan»);
elem.style.display = sel;}

More Examples
Example
A demonstration of how to use the contents property value. In the following
example the .a container will disappear, and making the child elements (.b)
children of the element the next level up in the DOM:
.a { display: contents; border:
2px solid red; background-color: #ccc; padding: 10px; width: 200px;}.b { border: 2px solid blue;
background-color: lightblue; padding: 10px;}
Example
A demonstration of how to use the inherit property value:
body { display: inline;}p { display: inherit;}
Example
Set the direction of some flexible items inside a <div> element in reverse
order:
div { display: flex; flex-direction: row-reverse;}
Override The Default Display Value
As mentioned, every element has a default display value. However, you can
override this.
Changing an inline element to a block element, or vice versa, can be useful for
making the page look a specific way, and still follow the web standards.
A common example is making inline elements for horizontal menus:
li { display: inline;}
Note: Setting the display property of an element only changes how the element is displayed,
NOT what kind of element it is. So, an inline element with is not allowed
to have other block elements inside it.
The following example displays <span> elements as block elements:
span { display: block;}
The following example displays <a> elements as block elements:

The display: inline-block Value
Compared to , the major
difference is that allows
to set a width and height on the element.
Also, with , the top and bottom margins/paddings are respected,
but with they are not.
Compared to , the major
difference is that does
not add a line-break after the element, so the element can sit next to other
elements.
The following example shows the different behavior of ,
and :
Example
span.a { display: inline; /* the default for span */
width: 100px; height: 100px;
padding: 5px; border: 1px solid blue; background-color: yellow; }span.b {
display:
inline-block; width: 100px; height:
100px; padding: 5px; border: 1px
solid blue; background-color: yellow; }
span.c { display: block; width:
100px; height: 100px; padding: 5px;
border: 1px solid blue; background-color: yellow; }
