This talk was made at The developers conference 2015 in the city of Florianopolis. During the talk I talked about how you can start to develop your own HTML+CSS frameworks. Starting with the subject of the disadvantages of use some of the largest framework available today and going through a lot of development philosophy and code standards, then a overview of dependency management and pre-processor tools (I really want to talk more about those two subjects but I had only 40 minutes to the talk). Important to highlight that the subjects discussed here are all focused in develop code scalable, organized, responsive and focused on performance.
