I'll try to explain.
Once you have submitted an article or something like this, the XOOPS system applies your css theme file.
This css controls the whole system appearance (colors, font styles e.t.c).
The css attach function is only to see a real preview of the content before submitting it. It doesn't attach anything fisically 'cause it will happen automatically once the content is submitted.
You are trying to change the font what you see while you're writing with koivi. But it isn't a real font, the font what you see is selected by the browser and it doesn't affect the code.
Once the content is submitted, your css file will be applied, overriding the default browser font.
For example, under Internet Explorer, the default font it's like Times New Roman, under linux it's different.
It's like form buttons, if you see a html form and you're under Windows XP the buttons will appear different than under Windows 98.
Other example, now I'm writing this post and the font that I see is "Times New Roman".
But when I submit it, it appears with "Verdana" style.
Why?
Because the XOOPS css theme file specifies that forum posts will have verdana font.
So, if in your CSS theme file you specify some kind rule which controls the font, for example:
body
{
font:10px Verdana;
}
You will see your published article with Verdana and size 10px.
If you don't control this, the browser will apply it's default font (in case of Internet Explorer, Times New Roman).
