Is your feature request related to a problem? Please describe.
The vuepress doc now only shows examples but no codes. Users can only get example code from the vuepress source code. Although some example codes are shown in markdown in the component folder, I find it hard to write because I have to maually formatting code every time I try to update them.

Describe the solution you'd like

I encountered a card layout style issue in my use of react-mdc-web suggesting that by https://github.com/material-components/material-components-web/blob/master/CHANGELOG.md#0.30.0, card layouts are no longer supported as used at https://github.com/react-mdc/react-material-components-web/tree/develop/docs/src/js/pages/CardPage.
