title: Cannot find module 'csstype'
body: <p>I'm new in react with typescript. I installed react, react-dom; then installed @types/react, @types/react-dom, everything fine, everything works, except that I get error <code>ERROR in [at-loader] ./node_modules/@types/react/index.d.ts:55:22</code> <code>Cannot find module 'csstype'</code>. So I looked to the file in this path, and notice that vscode underlines line - <code>import * as CSS from 'csstype';</code> with red line and marks as cannot find module. I tried <code>yarn add csstype</code>, <code>yarn add csstype -D</code>, did not help. Any idea how fix error? [App works with error]. </p>
