Hi dion77,
Before working with template modification, we would like to suggest you to turn off the Development Mode in Template Manager so that you can apply the changes on .css files.
In order to change the body-background image: You can open templates/ja_template/css/themes/selected_theme/template.css file, find lines (i.e)
body {
background: url(../../../images/body_bg.jpg) no-repeat center top #000
color: #444
font-family: Arial, Helvetica, sans-serif;
font-size: 13px;
line-height: 20px;
margin: 0;
padding-top: 30px;
}
.ja-mainnav .navbar {
color: #666
margin-bottom: 0;
margin-top: 0;
background: #f5f5f5
overflow: visible;
z-index: 11;
}
.ja-mainnav .navbar-inner {
min-height: 50px;
background: #f5f5f5
filter: progid:DXImageTransform.Microsoft.gradient(enabled=false);
border: 0;
-webkit-border-radius: 0;
-moz-border-radius: 0;
border-radius: 0;
-webkit-box-shadow: none;
-moz-box-shadow: none;
box-shadow: none;
padding: 0;
position: relative;
}
Then you can change the body-background image and main menu color you want.
And yes. We do publish the detailed documentations on T3 framework features (template layouts, mega menu, thememagic …).The documentations can be found in http://t3-framework.org/documentation.html
