Resolve CSS Confliction in React Project and Fix 6~8 CSS Issues

As the project growing, CSS becomes a bit messy and some redundant CSS need to be removed with care. The production build looks a bit different than dev build. This may caused by order of CSS files linked by WebPack, but I am not very sure. [login to view URL] The tasks in this small project are: 1. Resolve CSS Confliction in the React project; 2. Fix 6~8 CSS Issues (I can show you before you start) Please don't ask for source code which is expensive. You will work remotely on my computer via Team Viewer. Before pay you, I need to test in production server, and this may take 1 or 2 days.
