Navigation bar

I would recommend making the following changes in the child theme or a custom CSS area. (You can always use the Simple Custom CSS plugin)

[class*=” icon-“], [class^=”icon-“] {
width: 34px;
}
.navbar .nav > li > a {
padding:5px 35px;
}

As to the search area, see if this thread helps:

Glad it helped. The space between the words is set by the second number here:

.navbar .nav > li > a {
padding:5px 35px;
}

So, right now it is at 35px. If you want a smaller amount of space, just decrease that number until it’s how you want.

Good luck!
