Site Title won’t changes between shaded and unshaded

I got the premium version of the theme and I absolutely love it, but I wanted to emphasize my site title a little more and entered in some Additional CSS to create a text shadow, however the shadow randomly seems to disappear from page to page or post to post.

This is the code I’m using:

header .site-title a {
font-size: 65px;
}
h1.site-title {
text-shadow: 1px 1px 2px black;
}

Anyone have any idea why that may be?
