Font size in linked article

Hello,

Here is the link :
www.bsecure.info/index.php/component/content/article?id=68

I'm trying to do the size of the font bigger.I tryed to change settings in module manager,article manager and template manager.
I guess that must be the way to change it in the code of template.

Thanks in advance and best regards,

Michael.

Size of text is set by default font size for template. In layout.css:

html {
font-size:12px;
}

Thank you very much,Ivan, but it does not work.

I see there is still 12px in that file , are you sure you change it?

You can add below that

p{
font-size:15px;
}

where 15px is value you should change.

Hello again,Ivan.
I tried to change it but it doesn't work.
I want you to look at something...
This is what appears in inspect element:
