How does it work?

Web pages are simply made up of plain ASCII text. Web browsers process the codes used on web pages to display a fully formatted web page. But the pictures, colors, and other non-text items on a web page aren't actually on the web page itself -- the web page itself is simply text,
with the formatting and
graphics encoded. You
can look at the code for any web page by going to the "View" menu and choosing "Page Source".
