16 - Layouts

The User Interface (UI)

The portion of a Web page where users interact is called the user

interface (UI).

The layout of a user interface will dramatically impact a user

experience.

Layouts can range from minimalist with just a few elements, to pages

that are jammed full of content. Simple layouts and complex layouts require

different models to ensure that content displays properly for users.

To help ensure that CSS3 styles work during this transition phase,

many of the major Web browsers offer alternative property names. These

workarounds simply add avendor prefix, which is a keyword surrounded by

dashes, to the front of a CSS3 property name. Keep the following in mind as

you work with CSS3 properties:

• Internet Explorer uses the -ms- prefix.


• Firefox supports the -moz- prefix.


• Opera supports the -o- prefix.


• Chrome and Safari support the -webkit- prefix.
