Also, although the the topic is general in nature, the changes you want to make may be specific to your template (along with some changes to the Joomla core files) so you'd be best off posting in the forum for the template you are using.

If you let us know, we can move it for you, but most importantly, we'll need a link to a live site in the thread before we can suggest any changes.

So looking at the site, you have a Module then an Article beneath it with the title set not to show?

You can use text-transform:uppercase; in the template.css

However, all these items are grouped together, so you might want to create a new line with just the the css for the Article title and use text-transform:uppercase;

#rt-mainbody-bg, #rt-mainbody-bg .title, #rt-mainbody-bg .rt-article-title, #rt-mainbody-bg ul.menu li > a:hover, #rt-mainbody-bg ul.menu li.active > a, #rt-variation .bg4, #rt-variation .bg4 .title, #rt-variation .title4 .title, #rt-variation .bg4 ul.menu li > a:hover, #rt-variation .bg4 ul.menu li.active > a {
color:#666666;
text-transform:uppercase;

If you need further assistance on that, I suggest posting a new thread in the Crystalline forum, 'Article Titles only uppercase'

As far as moving the date above the title, there's no way to do that through the template's css because the template displays titles and dates based on the Joomla core.

So, I will leave this topic here, maybe somebody will know how to change that, but while you're waiting, you might want to search or post on joomla.org to see if someone has come up with a solution.
