CSS to CSS3 mobile website versions

When a past colleague needed a site for his new business, he asked me to create something unique to his needs as a service disabled veteran owned small business. He wanted a simple site with few images, and not in image top heavy styles typical on Weebly or Wix. He needed it set up quickly to support contracting bids. Because of the short deadline, we decided to adapt an existing template rather than start a fully custom site. I found a few open source CSS templates and used the one that he liked, then modified it to fit his own logo and branding color scheme. The template did not include mobile-friendly options. Once the site was launched, I created a modified style sheet for screen sizes between 50px and 500px, with a simplified banner/logo. I applied responsive web design media queries to the existing older style sheet to create a mobile version.
