[Twenty Eleven] Borders around menu

That will probably be padding on the list item tag. Can you provide a link displaying the problem and then I could take a look at the CSS.

Remove the line height and reduce the second value for padding on:

#access a {
    color: #1E598E;
    display: block;
    line-height: 4.333em;
    padding: 0 1.2125em;
    text-decoration: none;
}

in your child’s stylesheet.

The line-height in the parent’s CSS is now kicking in. Try adding line-height:2em; back into #access a.

You’re welcome. 🙂
