How do you make a webpage change its width automatically?

Question

In HTML, is there a way to make a webpage expand to the user\'s monitor? Like say I have a 15inch, but someone else has a 24 inch. The webpage would be small on their screen,

Answer 1

Unless you specify a specific width for any element of a webpage, such as the body or some containing div, it will expand to the width of the browser window.

If you're looking to set the size in pixels to the user's width, you can use javascript to set widths dynamically:

However, you should probably use a more fluid layout that will automatically expand by using widths specified in percents (e.g. setting the width of an element with CSS: width: 100%)
