Question Change default font size?

In the default_ex template, I need to change the default font size ... form "this" ... to "this" ... I followed the instructions in previous discussion to the best of my understanding, but no joy.

After making the suggest code change to kunena_forum_css for the default_ex template, the code looks like the following:

div.msgtext {
width: 100%;
overflow:hidden;
font-size:medium;
border-top:1px solid #ddd;
padding:10px 0 0 0;
margin-top:5px;
}
div.fbcode {
overflow:auto;
}
div.msgtext pre, div.msgtext .code {
border-left: 5px solid #F4A94F;
border-right: 1px solid #CCC;
border-top: 1px solid #CCC;
border-bottom: 1px solid #CCC;
font-family: "Courier News", monospace;
font-size-adjust: none;
font-stretch: normal;
font-style: normal;
font-variant: normal;
font-weight: normal;
line-height: 1.5;
margin: 5px 0pt 15px;
padding: 10px 15px;
width: 100%;
overflow:auto;
}

But, there appears to be no change whatsoever. Is it possible to dictate a specific default font size, such as "12pt?"

Any and all help is sincerely appreciated.

yes, possibly try

div.msgtext
width: 100%;
overflow:hidden;
font-size:14px;
border-top:1px solid #ddd;
padding:10px 0 0 0;
margin-top:5px;
}

swiarda, did you find the solution...?

If not, try this, put some thing like this: instead 14px or medium, write 50% or de value that you consider right...

Sorry for my english i´m doing the best that i can...

Regards.
