Well that sidebar markup doesn’t carry the widget class that you styled on so you will need to add :
#sidebar #sidebar-login-form to your widgets ruleset as a grouped selectors set :
`
div#sidebar div.widget,
#sidebar-login-form {
background: #fff;
border: 1px solid #AEE100;
-moz-border-radius: 5px;
-webkit-border-radius: 5px;
border-radius: 5px;
margin-bottom: 20px;
padding: 15px;
}
`
If you also wanted the login/ jin us text/button then you will have to add a division around that markup and the form and style that e.g:
`
all the sidebar form and text markup here
`
And replace the #sidebar-login-form above with #login-join-box on the ruleset.
