The website style needs fix

[astonzhang]

Likely causes would be some undesirable changes to static/frontpage/frontpage.html, style files, or lib dependencies.

@AnirudhDagar Can you take a look? Thanks.

Hi,

I have already fixed it and committed to the master branch.
@AnirudhDagar, could you merge the master to the release please?

Thanks,
