Almost Spring Modification

Ey,

I recently saw a post to add a header image to Almost Spring theme,you had to midfy the css header part from:

#header {
width: 450px;
height: 100px;
background: url(https://triponic.com/images/banner.jpg) no-repeat;
border-bottom: 10px solid #53A4FE;
}

/* Header styles */
#header h1 {display:none;
margin: 0;
padding: 35px 0 0 40px;
font-size: 2em;
line-height: 40px;
}
#header h1 a {
text-decoration: none;
}
#header p {
margin: 0;
padding: 5px 0 0 40px;
}

TO:

#header {
width: 450px;
height: 100px;
background: url(https://triponic.com/images/banner.jpg) no-repeat;
border-bottom: 10px solid #53A4FE;
}

/* Header styles */
#header h1 {display:none;
margin: 0;
padding: 35px 0 0 40px;
font-size: 2em;
line-height: 40px;
}
#header h1 a {
text-decoration: none;
}
#header p {
margin: 0;
padding: 5px 0 0 40px;
}

I have done it but it streched my menu to the right as you can see in https://triponic.com . ANybody know how to fix this?

Thank you.
