Unwanted Whitespace - html

Question

I asked a similar question recently about navigation buttons and having whitespace below and above and it was answered very well. Here is the question Navigation Buttons no whitespace underneathe
Basically now I have whitespace above the button and I need it closed.
Also I would like the text in the buttons to be center both vertically and horizontally.

Answer 1

Remove the border-bottom from hr to get rid of that small space above the options:
hr {
margin:0;
border: 0;
height: 0;
border-top: 1px solid rgba(0,0,0,0.1);
border-bottom: 1px solid rgba(255, 255, 255, 0.3);
}
And also add a line-height: 100px; to .navigation li a which will center the text vertically:
.navigation li a {
text-align: center;
padding: 30px 10px 10px 30px;
line-height:100px;
}

Answer 2

Add same line-height value as same value of the li height
.navigation li a {
text-align: center;
padding: 30px 10px 10px 30px;
line-height:100px;
}
