If you visit jointhegame.kde.org you will notice an horizontal scrollbar in your browser.
If the scrollbar is used, an user will be able to navigate the site but the pages will be transparent.
The first time I opened the site, instead of clicking the menu, I used the scrollbar

Reproducible: Always

Steps to Reproduce:
Open the website

Actual Results:  
The horizontal scrollbar is displayed

Expected Results:  
The horizontal scrollbar should not be visible

To hide the scrollbar you should use overflow:hidden; on the body or create an extra layer with overflow:hidden set.

in jointhegame.kde.org/style.css:
FROM:
body {
  background-color:#00AFEF; background-image:url(images/bg.gif);
}
TO:
body {
  overflow:hidden;
  background-color:#00AFEF; background-image:url(images/bg.gif);
}
