Google describes Material Design Lite (or MDL) as ‘a library of components for web developers’ and has created a site getmdl where you can work through the various elements step by step, alongside downloading the packages and even a few templates to get you closer to using the design. At the moment, MDL is not optimized nor supports the use of individual components, e.g. a button. Still, for developers wanting to use just a reduced number of MDL components, it is possible to tailor a custom MDL distribution by commenting out undesidered components from material-design-lite.css and undesired scripts from the Gulpfile.
