potential UI drawbacks

In SaleProducts route, the product list part at the bottom is not looking good in responsive view as the one on Landing page.
If the number of products in a category is less than 3 then the product list part looks cut like this.
magnifier part is not responsive.
Some avatars' links broken(The cause of this is image file name extension mistake like confusing .png with .jpg.)
product summary part disappears between breakpoints from 1200px to 1280px.

- TODO: handling(minor)
- localIdentName setting in webpack for avoiding css override by mistake and improving component level css.(minor)
- The styling in drawer UI is a bit different from the original, the point is it should look nice, not dead and dumb.(minor)
