What was the css codes used to add the underline and which page of EasyBlog has a link ?

at https://www.hausbauberater.de/ you see Wohnberechnungsvorschriften beim Hausbau with a link and underline.

at https://www.hausbauberater.de/bauwissen/badausstattung you see Baugrunduntersuchung with a link and no underline

There seems to be some inline styling on the color, http://take.ms/N9T2m but what you can do is to add the codes below:

[gist]
body #eb a,
body #eb a:link {
color: #000;
font-weight: normal;
font-style: normal;
text-decoration: underline;
}
