Fixed #57 (Search bar not visible)

[eshantri]

This PR fixes issue #57 .
Issue
Search bar becomes invisible after something is typed into it.

Fix

1. Minor css fix, the fix disables the overflow on the y-axis, in Documentation view.
2. Have attached the videos for tests on Chrome and Firefox. In the test, I type in the bar, the search focuses highlighted elements, then we press backspace key which deletes the input, upon scrolling up we observe the search bar is still present.

@eshantri unless we are going to need the code in the future, would it be better to just delete it instead of commenting it out?
