Changing the Icons in a WebHelp Classic Table of Contents
You can change the icons that appear in a WebHelp Classic table of contents by assigning new image files in a custom CSS file. By default, the icons for the WebHelp Classic table of contents are defined with the following CSS codes (the first example is the icon that appears for a collapsed menu and the second for an expanded menu):
.hasSubMenuClosed{
    background: url('../img/book_closed16.png') no-repeat;
    padding-left: 16px;
    cursor: pointer;
}
            .hasSubMenuOpened{
    background: url('../img/book_opened16.png') no-repeat;
    padding-left: 16px;
    cursor: pointer;
}
            To assign other icons, use the following procedure:
- Create a custom CSS file that assigns your desired icons to the
                  .hasSubMenuClosedand.hasSubMenuOpenedproperties..hasSubMenuClosed{ background: url('TOC-my-closed-button.png') no-repeat; }.hasSubMenuOpened{ background: url('TOC-my-opened-button.png') no-repeat; }
- It is recommended that you store the image
                     files in the same directory as the default icons.- For DITA transformations: DITA_OT_DIR\plugins\com.oxygenxml.webhelp\oxygen-webhelp\resources\img\.
