Uncapitalize the post title [NSFW]

My link is https://explore-your-sexuality.com

I did look through the forum and find what I thought was going to solve my problem, but it didn’t. I want my post titles to look like this “How to Achieve an Amazing Orgasm” instead of “HOW TO ACHIEVE AN AMAZING ORGASM”. So what I did was changed this code from:

.post-title h2{
	font-size:2.0em;
	color:#000;
	font-weight:normal;
	text-transform:uppercase;
	padding:0 5px 0 0;
}

to:

.post-title h2{
	font-size:2.0em;
	color:#000;
	font-weight:normal;
	text-transform:none;
	padding:0 5px 0 0;
}

But it didn’t change anything.
