Working on medium to large scale web projects, CSS can get away from you really quickly. Without an honest methodology and process for managing your UI assets, failure is almost certain.
This presentation illustrates the failures of many cross team large scale projects. Poor reuse of CSS and HTML and the failure of the design comp process.
Discussed are techniques for using a styleguide framework, templating solutions, elemental and modulare development patterns in the UI and how they will totally save your bacon!
