A site which is built to be responsive will adapt its layout to the screen size it is viewed on. The coding of the site calculates the browser width and will re-style the content in a way that is optimised for that width.
This is different to a mobilised website, which may share content but will have a lot of its own code and likely to have a different URL. For this kind of site, you should read about device detection.
Dedicated mobile sites are popular for sites which require more user interaction, such as e-commerce sites. However, responsive websites have the advantage, if executed well, of looking great on any screen – a desktop, a games console hooked up to a widescreen TV, a tablet, or a phone.
The method chosen will depend on the project, its aims, and its audience. Both can be created with Contensis.
Contensis templates can be built using a fluid grid concept and images styled with relative units. The CMS keeps content and design structure separate. If a site is built with responsive templates, it will not alter how content editors work.
