There are two ways to do this. You can use an image or the existing text.
To use an image, follow the steps below:
If you look in your template_css.css file you'll see:
/* $2 - Header Styles */
Just below that you'll see a few classes; .header-logo, .header-logo h1 a, and .header-logo h2
Change these to read:
.header-logo {
height:111px;
padding:0px;
}
.header-logo h1 a {
color: #FFF;
padding:0;
margin: 0;
text-decoration: none;
display: block;
width: 360px; /* You can set the width here */
height: 110px; /* Maximum height is 110px */
text-indent: -5000em;
background: url(../images/header-logo.png) no-repeat left center;
}
.header-logo h2 {
color: #8C0000;
padding:0;
margin: 0;
width: 0px;
height: 0px;
display: none;
text-indent: -5000em;
}
Save and upload. You'll see the image appear:
You can create your own using the attached source file.
