Responsive web design is about creating web sites which automatically adjust themselves to look good on all devices, from small phones to large desktops. This website is a responsive website, so it should work on any device.
This css is developed by me. It can include whatever design elements needed to make your website look its best.
Bootstrap allows me to create so many different websites. Along with my own css, I can create one of the best looking websites for whatever you need. Don't take my word for it. Look at some of my work to see how I take websites that look like they're from the '90s and bring them into the 21st century.
