Ok, the entire sidebar that holds the Logo, Nav, and other content that you add into the “Header Right” widget area is all inside a div called “head-wrap“. 聽You should be able to decrease the width by looking for .head-wrap in your css. 聽It should be around line 198 in your css –
.head-wrap {
float: left;
padding: 40px 20px 20px 0;
width: 20%;
}
