How can I modify default style...with CSS file

[imgnrm]

Hello,
I would like to modify Some CSS from default style but I would like to leave it as is.
Is there any way I can download the actual CSS files of default Style so that I can make some changes such as font size and color and some space?

I learned I can use actual CSS by uploading new file in /core/clientscript/vbulletin_css/
But it seemed that I need to write the CSS from scratch.

I would like to download or duplicate the default CSS and modify from the default style.

Please advise me.

Thank you.

You would add custom CSS to the template css_additional.css.

It is not a file, it is a template in the style manager within the admincp.

Hello Mark,
Then, where should I put the css_additional.css? and how to link the page in where?

You can also customize by changing stylevars in the Style Variable Editor.
