Part of the user interface design is affected by the quality of the page layout. A designer may consider whether the site’s page layout should remain consistent on different pages when designing the layout.

Page pixel width may also be considered vital for aligning objects in the layout design. The most popular fixed-width websites generally have the same set width to match the current most popular browser window, at the current most popular screen resolution, on the current most popular monitor size.

• Most pages are also center-aligned for concerns of aesthetics on larger screens.
• Fluid layouts increased in popularity around 2000 as an alternative to HTML-table-based layouts
• Web designers may choose to limit the variety of website typefaces

The page layout and user interface may also be affected by the use of motion graphics. The choice of whether or not to use motion graphics may depend on the target market for the website. Motion graphics may be expected or at least better received with an entertainment-oriented website.

Website designers may consider it to be good practice to conform to standards. This is usually done via a description

Failure to conform to standards may not make a website unusable or error prone, but standards can relate to the correct layout of pages for readability as well making sure coded elements are closed appropriately.
