HTML background that fits the screen

You can actually define an image or a background (with CSS) that fits the area in which is it shown.

For a simple image use a width of 100%, then the browser computes the height for you.

  <div class="header"><img src="images/background.png" width="100%"></div>

This code will make the image width match the width of the <div> tag. Assuming the <div> tag fits the screen width, it will show in the full width, stretching as required.

    There are several ways to use the term key in software development. You may have heard it a lot in regard to public and private keys. Those are used to encrypt and decrypt data sent over the wire. Another way is when you want to sort a large number of entries in a database. In that case, you most likely will need a unique key. For example, a page on the Internet is defined with a URI. You may define a canonical version of that URI making it unique. That canonical version is called a key for that page.
