How to change the font size for a SINGLE VALUE panel?

[maximusdm]

I am following the instructions from:
https://docs.splunk.com/Documentation/Splunk/6.5.1/AdvancedDev/UseCSS

without any luck. If I convert the Dashboard to HTML and use everything works but I need to use XML format.
Here is a screen shot of my TEST dashboard:

The Dashboard belongs to the ' search' application. Any ideas?
I also downloaded File Monitor for Windows so that I could monitor the file paths (files) that Splunk access. I just cannot see anything in my trace, for instance, an app accessing the file dashboard.css; This is so frustrating.

Convert your dashboard to html and add below &lt/heade&gt

&ltstyle&gt
.single-value .single-result {
font-size: 1000px !important;
}
&lt/style&gt

not sure what happened but it is working now. I even restarted Splunk many times without any change but something happened that this thing is working now.
