rendering bug in konqueror (kde 3.5) ?

[Matthias Pospiech]

If you visit this site: http://www.cqa.de/, which I have build a year ago or
longer you will notice a wrong navigation bar (horizontal top navigation).
The same page looks correct in firefox.

Can one, state whether my code or the rendering is wrong ?
Here the css code:

/* Horizontal nav */

#minitabs {
background-color: #345fd8;/*#6b85d3;*/
margin-left: 0px;
padding: 0 0 0px 0px; /*20px 10px*/
/*border-bottom: 1px solid #000;*/
}

#minitabs li {
margin: 0px;
padding: 0;
display: inline;
list-style-type: none;
}

#minitabs a:link, #minitabs a:visited {
/*font-family: Verdana, Geneva, Lucida, Arial, Helvetica, sans-serif;*/
float: left;
font-size: 12px;
line-height: 14px;
font-weight: bold;
letter-spacing: 2px;
margin: 0 10px 0px 10px;
padding-top: 4px;
text-decoration: none;
color: #fff;
/*color: #fff;*/
padding-bottom: 5px;
font-style: normal;
}

#minitabs a.active:link, #minitabs a.active:visited, #minitabs a:hover {
border-bottom: 4px solid #ffb539;
background-color: #4c73e0;/*#6b85d3/*#ffb539;*/
color: #fff;/*#2244aa;*/
font-style: normal;
}

#minitabs a:hover {
border-bottom: 4px solid #ffb539;
background-color: #4c73e0; /*#6b85d3;/*#ffb539;*/
color: #fff;
font-style: normal;
}


(BTW: it was never correct, but in the new version it looks more uncorrect
than ever before)
