Most clients allow you to customise the way they display the
marked up
page that you have retrieved. This is a bone of contention
between some people about WWW - the fact that individuals
may see the
author's data in very different ways seems curious in the
extreme to
people from the publishing world, where standards of layout are
very
fixed (and high). 
At the very least, a system will let you change the way it displays anchors, and possibly the type of font used. Most graphical clients let you delay or prevent image loading, so that they are usable over slow links, though not everyone who provides information on the Web appreciates how this affects the look of a page. Of course text based clients such as Lynx can't display inline images in the first place.
