Website Design for Different Browser Sizes
One of the variables that web designers have to deal with during the design process is the continually changing screen resolution of Internet users. Not that long ago, an 800px x 600px screen size was the norm. These days, most people have at least a 1024px x 768px screen. Of course, you still have users who are stuck in the dark ages, with screen resolutions of 640px x 480px, and you have some users who connect to the Internet via their HDTVs, giving them a screen resolution of 1920px x 1080px.
So, how do you, as a web designer, deal with this constantly changing landscape? Well, there’s no easy answer to this. Some designers opt to create pages that are scalable, so they always fill the entire web browser. Others hedge their bets by limiting the width of their sites so they fit within the most common browser size. There are upsides and downsides to both of these approaches, but in both cases, there are other factors to consider.

If you’re relatively new to web design, you’re probably still learning how to get your pages to look the same in all browsers. Even more important, though, is learning how to get your pages to function correctly in all browsers.
