Hallo, I'm absolutely web design un-kissed noob and I'm trying to make my website on tumblr.com. I've bought a html template plus I got a small CSS with it.
When I right-click the site and get the source code, this is it:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
	"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<head>

Then here is the CSS code:
Code:
#page title { font-family: Times new roman, sans-serif;font-size: 42px; } 
 
.icon_permalink, .side_meta .tags { display: none; }
.icon_posted, .side_meta .tags { display: none; }
 
#nav li { font-family: Times new roman, sans-serif; color:#6f6f6f } 
body { background: #fff; }
#loader { background-color: #fff; }
#nav_page { color:#00ffff }
#search,
.panel_head,
.panel_foot,
.ref,
.meta li,
.meta a,
#page .quote blockquote.quote_text .quotemark,
#page .link h2 .icon,
#page .link h1 .icon,
.artwork,
.player_head,
.player_foot,
.player_foot,
.audio_download a,
.inline_audio .artwork,
#page .answer .qa,
#sidebar .has_icon .icon,
.side_meta .avatar_frame,
#meta .has_icon .icon,
#meta .avatar_frame,
#notes .has_icon .icon,
#pagination li a,
.footer_links .has_icon .icon,
.side_meta .has_icon .icon,
#loader p,
.meta_foot p.source a {
	background-image: url("http://static.tumblr.com/lhq9par/cm3l8yrtu/sprites_ffffff.png");
}
What I need is to have these links to my sub-pages in other color than black as it is now.
Code:
<ul id="nav">
			<li class="nav_home"><a href="/">ÚVOD</a></li>
			<li class="nav_page"><a href="/kontakt">Kontakt</a></li><li class="nav_page"><a href="/sluzby">Služby</a></li><li class="nav_page"><a href="/verzak">Veřejné zakázky</a></li>
 
 
 
		</ul>

Somebody on other forum replied to me, that this code should work, but nothing happened :-(
Code:
#nav a { color: yourColour }

I don't know if I'm so much noob or there's some problem on tumblr's side.
Please, if somebody has 5 minutes for me, contact me via PM and I will send you login for my tumblr and you can look at it, just if you want...
Thanks a lot, it hurry a bit and I'm suffering from this...

Thank you very much for your time...
