Spacing of navigation menu

My blog is at https://www.thekoreanmang.com.

I want my menu at the top (the three links) to line up with the name of the post directly under it. I go into the CSS and this is the code for the menu.

#access a {
    color: #000;
    line-height: 2em;
    margin: 0 1px 0 0;
    padding: .25em 1em 0;
    text-decoration: none;
}

It seems that the padding part of this code is what I need to change. But when I change the ‘1em’ value to ‘0’, the links line up with the post title below it but then all of the links are squished together.

How can I get the links to be aligned with the post title and have proper spacing in between each link?
