Why this text is not showing?

In this page, there's a box on the right side with tabs, and the Bl开发者_运维百科og tab is not showing the text, why?

---

Text color is white, as is the background.

a.linkblog:link {
    color: white;
}

---

Because the link color is set to white:

a.linkblog:link {
    color: white;
}

Now, next time use a tool like Firebug or the WebKite Inspector (hit Ctrl + Shift + I in Safari / Chrome) and find it out yourself :)

Change the Css

a.linkblog:link {
  color:#FFF;
}

to something like

a.linkblog:link {
  color:#000;
}
