Media Query not taking effect - css

Question

I have never had a problem with a media query like this before. Normally, it just does something unexpected, but not nothing. I don't need help with the actual effect, just as to why it isn't seeing the query. If you inspect the code, it is just not there. I referenced several other posts, but I have it formatted the same as far as I can tell, syntax wise.
Here is my HTML:
<div id="content_main">
<div id="bottom">
<div id="discord">
<div id="header_headset">
<h1>See who's online:</h1>
<div id="headset"></div>
</div>
<iframe src="https://discordapp.com/widget?id=90178023529127936&theme=dark" width="320" height="500" allowtransparency="true" frameborder="0"></iframe>
</div>
<div id="news_announcements">

</ul>
</div>
</div>

<h2>Not playing your favorite game?</h2>
<p>Here at CommonRoomGaming.com we don't discriminate against any games. If you want to play a game, odds are others have it and want to play it too! So with that said, if you don't see your favorite game listed, feel free to suggest it by letting us know in the below form.</p>
</div>
<div id="SAG_form">
<FORM action="emailit.html" method="POST">
<TABLE border="0" width="100%">
<TR>
<TD>Your name and/or handle:</TD>
</TR>
<TR>
<TD>
<INPUT type="text" size="30" maxlength="40" name="name"></INPUT>
</TD>

<TEXTAREA name="message" rows="4" cols="50" style="width:300px" ></TEXTAREA>

</TR>
</TABLE>
<P>
<INPUT type="submit" value="Make it so."></INPUT>
</P>
</FORM>
</div>
</div>
</div>
</div>
And here is my media query:
#media screen and (max-width:500px){
#bottom {
width:350px;
display:block;
margin-right:auto;
margin-left:auto;
}
}
Here is my codepen of the whole document link
Again, I only need to know what I am doing wrong with the media query. Ignore anything unrelated, as it is all changing.
