Fixes #467

@dantownsend I have added bit extra styling. Let me know your thoughts. The border radius isn't consistently applied to all places though.

Thanks for this 👍

Is the 5rem the approx height of the top nav bar?

[abhishek-compro]

It is a rounded off value and enough to not put a global scroll bar. The only thing is that there is a slight footer padding which is both a good and bad thing depending on how you see it.

@dantownsend @sinisaos

1. Have fixed horizontal scroll as well (previously scrolling horizontally would move action buttons out of sight / screen)
2. Now buttons (including buttons using anchor tags) have consistent hover and active effects. Have removed the scale transform and am relying mostly on background color change on hover.
3. The close button on filters page is now red in color

Let me know if you need any modifications.

@abhishek-compro That looks good to me 👍
