In Chapter 7 you learned about building fixed and flexible layout grids
as well as setting limits on flexible layouts by using the
min-width
and
max-width
properties. You can use these techniques to make adaptive
layouts that find a compromise between the best presentation and read-
ability of the content and the visitor's browser dimensions.
But what if you could adapt the layout from the standard two-column
layout into a one-column layout for narrower browsers or bring the
footer up into a third column for the insanely wide screens? Or what if
you could adjust the size of header type or swap background images
