Having a responsively designed website is increasingly becoming more important as more Internet devices are being brought to market. Having a theme design that can respond to different screen sizes means you only need to develop and update one version of your website. You can test any domain below and see how the site responds to various common screen widths. If areas of the website flow off the right side on the screen, or the page content requires horizontal scrolling, then, the site is not responding to that peculiar device width. Note: The content below will not display in small devices properly.
