CSS Display Visibility: The display property is the most important CSS property for controlling layout.


In this tutorial, you will learn-

The display Property

The display property specifies if/how an element is shown.

Every HTML element has a default show value depending upon what type of element it is. The default show value for most elements is block or inline.


Block-level Elements

A block-level element consistently begins another line and takes up the full width accessible (stretches out to the left and right as far as it can)

The <div> element is a block-level element.

Examples of block-level elements:

  • <div>
  • <h1> – <h6>
  • <p>
  • <form>
  • <header>
  • <footer>
  • <section>

Inline Elements

An inline element does not start on a new line and only takes up as much width as necessary.

This is an inline <span> element inside a paragraph.

Examples of inline elements:

  • <span>
  • <a>
  • <img>

Display: none;

show: none; is normally used with JavaScript to hide and show elements without erasing and recreating them. Take a look at our last example on this page if you want to know how this can be achieved.

The <script> element uses display: none; as default. 


Override The Default Display Value

As referenced, every element has a default show value. Be that as it may, you can override this.

Changing an inline element to a block element, or the other way around, can be useful for making the page look a particular way, and still follow the web standards.

A typical example is making inline <li> elements for horizontal menus:

Example

<!DOCTYPE html>
<html>
<head>
<style>
li {
  display: inline;
}
</style>
</head>
<body>

<p>Display a list of links as a horizontal menu:</p>

<ul>
  <li><a href="/html" target="_blank">HTML</a></li>
  <li><a href="/css-tutorial" target="_blank">CSS</a></li>
  <li><a href="/javascript" target="_blank">JavaScript</a></li>
</ul>

</body>
</html>

Note: Setting the display property of an element just changes how the element is displayed, NOT what sort of element it is. Along these lines, an inline element with display: block; isn’t allowed to have other block elements inside it.

The accompanying example design <span> elements as block elements:

Example

<!DOCTYPE html>
<html>
<head>
<style>
span {
  display: block;
}
</style>
</head>
<body>

<span>A display property with a value of "block" results in</span> <span>a line break between the two elements.</span>

</body>
</html>

The following example displays <a> elements as block elements:

<!DOCTYPE html>
<html>
<head>
<style>
a {
  display: block;
}
</style>
</head>
<body>

<p>Display links as block elements:</p>

<a href="/html" target="_blank">HTML</a>
<a href="/css-tutorial" target="_blank">CSS</a>
<a href="/javascript" target="_blank">JavaScript</a>

</body>
</html>

Hide an Element – display:none or visibility:hidden?

Hiding an element can be done by setting the display property to none. The element will be hidden, and the page will be shown as if the element isn’t there:

Example

<!DOCTYPE html>
<html>
<head>
<style>
h1.hidden {
  display: none;
}
</style>
</head>
<body>

<h1>This is a visible heading</h1>
<h1 class="hidden">This is a hidden heading</h1>
<p>Notice that the h1 element with display: none; does not take up any space.</p>

</body>
</html>

visibility:hidden; also hides an element.

However, the element will still take up the same space as before. The element will be hidden, but still affect the layout:

<!DOCTYPE html>
<html>
<head>
<style>
h1.hidden {
  visibility: hidden;
}
</style>
</head>
<body>

<h1>This is a visible heading</h1>
<h1 class="hidden">This is a hidden heading</h1>
<p>Notice that the hidden heading still takes up space.</p>

</body>
</html>
