The CSS display: property allows developers to explicitly specify and/or change the display properties for any element, including the option to “hide” an element. This greatly increases a developer’s ability to create layouts that support the presentation of content in a web browser.

The display: property is called on the actual element it is being applied to (as opposed to a parent element holding child elements).

The three main display properties that we’ll discuss are:

block
inline
inline-block

Inline

The display: inline; rule forces elements to act like inline elements. Inline elements, unlike block-level elements:

only take up as much horizontal space as is needed (ignores width properties).
do not force new lines.
“flow” with content on the screen, and as such, do not respect the margin property.
cannot change the vertical (top/bottom) distance between themselves and other elements.

Inline-Block

The display: inline-block; rule, like display: inline;, removes new lines inherent in block elements. Unlike display: inline;, display: inline-block; also forces elements to respect margin and vertical spacing properties/rules.

However, this also means these elements will expand horizontally to fill the parent-container. Therefore, you must explicitly set the width of these elements.

Block

Just like the display property can be used to turn ‘block’ elements into inline or inline-block elements, it can also be used to turn ‘inline’ elements into block elements. This technique is often used to create vertical menus out of lists.
