Summary

Layout

• elements are often used as containing elements to group together sections of a page.

• Browsers display pages in normal flow unless you specify relative, absolute, or fixed positioning.

• The float property moves content to the left or right of the page and can be used to create multi-column layouts.

• (Floated items require a defined width.)

• Pages can be fixed width or liquid (stretchy) layouts.

• Designers keep pages within 960-1000 pixels wide, and indicate what the site is about within the top 600 pixels (to demonstrate its relevance without scrolling).

• Grids help create professional and flexible designs.
• CSS Frameworks provide rules for common tasks.
• You can include multiple CSS files in one page.
