Responsive Design is the buzz word of the web industry right now, and for good reason! Mobile devices like phones and tablets are the fastest growing area of technology right now. Many sites are starting to see anywhere from 20-40% of their traffic coming from mobile devices. Unfortunately by default the average website doesn't work well on those devices. The text is to small, the links are hard to click, and to use anything requires a ton of pinching and zooming to find what you're looking for. That's where Responsive Design comes into play.
Sites that are responsive adjust the content to work well on any device. Columns reflow into one column, font-sizes increase, and menu's adjust to be mobile friendly. Take a look at TitaniumSites.com on your mobile phone to see an example of how things adjust on different screen sizes.
What does this mean for you? Well it's all good news! Your TitaniumSite themes are already responsively designed for you!
Sites are no longer static "poster-like" designs, but dynamic and fluid. This can take some getting used to, but has so much potential for creating really useful sites. Instead of focusing on layout, focus on creating great content! That's what your customers are coming for, and that's what will ensure your site becomes/remains successful! Let TitaniumSites take care of the fluid "container" that your content lives in!
