can we reduce the gap of up and down of main menubar

Do you mind to provide your web address ?

Do not edit the theme itself. First create a child theme for your changes. Or install a custom CSS plugin.

Yes,

Tempera Settings > Miscellaneous Settings

In the Custom CSS area

#access {

display: block;

float: left;

margin: 5px auto 0;

}

#main {

clear: both;

padding: 0px ;

margin-top:5px;

}

I put mine at 5px on both the upper and lower spaces.
