Responsee framework comes from Vision Design graphic studio. At the beginning of that project there was an effort to optimize our time needed for creation of operational html and CSS layout. We tested several similar open-source frameworks, however none of them, even in spite of their indisputable qualities, satisfied us for 100%. Therefore we full of enthusiasm started development of our own minimalist and extremely useful framework. Several weeks of development resulted in unique responsive CSS framework, which fully meets our requirements.
