Label is getting displayed below checkbox

<%= f.check_box :openid_enabled %>
<%= f.label :openid_enabled, 'OpenID' %>

Above code generate this HTML

<input type="hidden" value="0" name="application[openid_enabled]">
<input type="checkbox" value="1" name="application[openid_enabled]" id="application_openid_enabled">
<label for="application_openid_enabled">OpenID</label>

and the label is getting displayed like

[x]
OpenID

instead of

[x] OpenID

Do I need to style it or rails helpers have some build in functionality?
