Why is my CSS Class style not applying to specific <li>'s?

Answer: This was a dumb mistake, was using '//' for single line comments instead of wrapping in /**/ (been writing too much javascript lately) Thanks for help, sorry for wasting time.

I cannot figure out why this CSS is not applying only to certain li's..

Here is the CSS: (notice the comments it says what does and doesn't apply - it is strange because the facebook link does recognize the class 'post-face' of the parent li and applies the link color but the actual li is not recognizing the class on the edit or facebook li's but it does on the twitter and comment li with the exact same code)

.SL .post .post-det .post-tweet {
    /* DOES APPLY */
    background: url(images/post-tweet-icon.png) no-repeat left 2px;
}
.SL .post .post-det .post-tweet a { color:#008ebc; } /* DOES APPLY */

/* FACEBOOK SHARE ADDON */
.SL .post .post-det .post-face {
    /* THIS DOESN'T APPLY */
    background: url(images/post-tweet-icon.png) no-repeat left 2px;
}
.SL .post .post-det .post-face a { color:#A1A1A0; } /* THIS DOES APPLY */
/* END FACEBOOK SHARE ADDON */

.SL .post .post-det .post-edit {
    /* THIS DOESN'T APPLY */
    background: url(images/post-edit-icon.png) no-repeat left 2px;
}
.SL .post .post-det .开发者_JS百科post-edit a { color:#ff0000; } /* THIS DOES APPLY */

Here is the HTML:

This rule is pointing to the wrong icon:

.SL .post .post-det .post-face {
    background: url(images/post-tweet-icon.png) no-repeat left 2px;
}

images/post-tweet-icon.png should probably be images/post-face-icon.png.

Not sure about the other one... what's the exact HTML that's generated by the edit_post_link() function?
