.text_gray { color:#cccccc }
The above code is nested in <style>.

And the below code is in main body.
<span class="text_gray"> 2004-08-25 </span>
I am expecting the color of the text "2004-08-25" is gray, but it actually is default color "black."

Why doesn't this "class" work?

you will understand more clearly about it.

Thanks in Advance
