Stylesheet.css not saving when updated? Changing Blog Page Template?

Hey all,

I’m relatively new to using WordPress and I am trying to do some work on a website that we hired an outside consultant to develop (who is unresponsive at this point). I was just looking for a little help.

I’m trying to go into Style.css to change the font color of the widget in the primary widget section.

Here is the link to my website, the section I am attempting to change is on the bottom right side bar under IBS Ambassador Blog/next to Universities We Work With.

Problem 1

}
#content .right li a {
	font-family: "Sanchez Regular";
	font-size: 16px;
	font-weight: normal;
	color: #f3f8fc;
	text-transform: uppercase;
	text-decoration: none;
	display: block;
	padding-left: 40px;
	padding-bottom: 0px;
	padding-top: 6px;
	padding-right: 0px;
	letter-spacing: -1px;
	height: 45px;
}

I believe this is the correct section and I have tried to change the color from #F3F8FC to another but every time I update it, it just reverts back to #F3F8FC instead of the color I had inputted (#64AFE1).

What can I do to make this change stick?

Also, I’m having some trouble with figuring out how to improve the aesthetic appeal of the blog postings displayed under the IBS Ambassador Blog above.

Here is an example of one of them. It is using the Twentyten Template I believe, whereas the rest of my site is a customized template (I BELIEVE).

Problem 2

I have tried to add a featured image to the top but whenever I upload it, it doesn’t display the image at all.

I’m also wondering how I can make the area underneath the actual blog post look better as well.

I started looking at the single post (single.php) and the loop-single.php but I have no idea where to begin.

I really appreciate any help that I can get!
