<div> - using div tags wiithout creating a new line.

Normally <div> would force a new line, but occasionally you might not want this to happen.

e.g.

<div>Hello</div> <div>World</div>

Displayed as:

Hello
World

To prevent this bahaviour you would use the inline display style

e.g.

<div style="display:inline">Hello</div> <div style="display:inline">World</div>

Displayed as:

Hello World
