‘Responsive’ web design is a concept that is now well established and is used to make websites look good on wide screen desktop computers, right down to small screen smart phones.
I program in the ability to dynamically move elements of your web site around on the screen so that dimensions, positioning of elements on the page, and font sizes all change according to the size of screen they are viewed on.
All browsers on smart phones and tablets will support HTML5/CSS3 fully so sites will 'respond' when viewed on them
It’s more work than a static site, but it is a cheaper option than paying for a separate mobile version of your web site, or an app. The variety of devices available to view web pages is increasing all the time, and so making a web site responsive is the only way to future proof it.
