CSS: Display Property

Display Property

CSS display property lets you control layout.

It is one of the most powerful property for layout, but is complex to understand.

Here is the basics.

There are 2 major types of “rendering box” for a HTML element:

block: The element flows from top to bottom, with a gap above it and below it. e.g. h1, div, p, pre.
inline: The element flows from left to right. e.g. span, strong (bold), a (anchor/link)

Example

Here is a example of changing list items as inline.

Here is a list, without style:

one
two
three

<ul>
<li>one</li>
<li>two</li>
<li>three</li>
</ul>

Here is the same list, but each li set to display:inline:

one
two
three

<ul>
<li style="display:inline">one</li>
<li style="display:inline">two</li>
<li style="display:inline">three</li>
</ul>

What is Rendering Box Type?

The details are fairly complex, but basically it's like this.

Each element, has a “rendering box type”. It determines 2 things:

How it is positioned with respect to its neighbor elements. example: block level (like a paragraph p), inline (like a bold b word in a sentence.), table (like block but width does not span the window width, it's shrink wrapped to the table's content's width, which is automatically computed by default.), and others.
How its children elements behave. example: table, ul (list), their child elements all have special type of rendering box.
