CSS Layout - The display  Property
❮ Previous Next ❯
The display property is the most important CSS property for controlling layout.

The display Property
The display property specifies if/how an element is displayed.

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

Click to show panel

This panel contains a <div> element, which is hidden by default (display: none).

It is styled with CSS, and we use JavaScript to show it (change it to (display: block).

Block-level Elements
A block-level element always starts on a new line and takes up the full width available (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;
display: none; is commonly used with JavaScript to hide and show elements without deleting 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 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 <li> elements for horizontal menus:

Example
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 display: block; is not allowed to have other block elements inside it.

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

Example
span {
    display: block;
}
»
The following example displays <a> elements as block elements:

Example
a {
    display: block;
}
»
Hide an Element - display:none or visibility:hidden?
display:none

Remove

visibility:hidden

Hide

Reset

Reset All

Hiding an element can be done by setting the display property to none. The element will be hidden, and the page will be displayed as if the element is not there:

Example
h1.hidden {
    display: none;
}
»
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:

Example
h1.hidden {
    visibility: hidden;
}
»
