Sample UI Changes

Changing foreground and background colors for menu titles (Dashboard, Configure, Manage, etc)

You have to modify the governance style bundle "main.css" which is in the org.wso2.governance.styles-3.5.1.jar (wso2greg-3.5.1\repository\components\plugins\org.wso2.governance.styles-3.5.1.jar\web\admin\css).

Please edit line 63 in the "main.css" as follows;

div#menu ul.main li.menu-header
        {
            background-image: none; (as from the carbon styles there is a background image for this)
             background-color: #dddddd;
            color: #f47b20;
            border-bottom: solid 1px #ffffff;
        }

        wso2greg-3.5.1\repository\components\plugins\org.wso2.carbon.ui-3.0.1.jar\web\admin\images\down-arrow.gif
        wso2greg-3.5.1\repository\components\plugins\org.wso2.carbon.ui-3.0.1.jar\web\admin\images\up-arrow.gif

Hover this is only working for the menu items which are links, "Add" and "List" menu items are act as subtitles. You can change these Subtitle styles by adding the following styles to the "main.css".

            background-position:16px 2px;
            background-repeat:no-repeat;
            border-bottom:1px solid #FFFFFF;
            border-top:1px solid #FFFFFF;
            color:#111111;
            cursor:text;
            display:block;
            font-weight:normal;

div#menu ul.main li a.menu-default:hover
        {
            background-color: #F5EDE5;
            border-bottom: solid 1px #DBC1A6;
            border-top: solid 1px #DBC1A6;
            color: #00447C;
        }
