The homepage graphic gives a visual to the concept of how much faster SCALGO's software processes massive data next to a call-to-action button to learn about the technology behind their products. The site colors are meant to be striking without being flashy considering SCALGO's scientific and academic audience.
In optimizing for the different widths I reduced the size and amount of graphics along with the size of certain items such as the footer links, making them larger and farther apart for easier touch-use in the 480 and 320 style sheets.
I built the site with HTML5 and other CSS3 elements such as border-radius and pseudo-classes. The site also uses selectivizr.js and Scott Jehl's respond.js for pseudo-class and media query recognition in Internet Explorer 7+.
Every site page has a main H1 summarizing the page's main idea with a background graphic matching the section to which it belongs.
I also incorporated a modified jQuery function on the individual product pages to provide each module's details without overwhelming the intial view of the page. The user can click "read details" to reveal further information and images, then the corresponding "hide details" to close it.
