suggestion about the UI design of examples in Components part

[Lexi2333]

the UI design of examples in Components part isn't convenient to compare the whole codes, especially when the screen is not long and wide enough. Even the screen is wide enough, when the lines of codes is very long, we still need to drag the bar back and forth, up and down. Here are my suggestions：

1. use one-column layout instead of the current two-column layout:
   two-column is too crowd to present so much content;
2. reduce the font size and line spacing of codes:
   so that we can see the whole code with out drag and drag.
   If you have spare time, you can also add a button to zoom in and out the codes' font-size.
   Meanwhile， the font-size and line-space of the whole page is too big either.
   ( why the codes is largger than the description above???)
   In compare, I put the screen shot of Element UI, it is much clear than yours.
   I mean AntD is excellent， I just hope it to be better.

Thanks
