Change Post Title font size

The best way to identify the CSS to change is using Firebug. But if you post a link to your site, someone may be able to help you with it.

I’ve tried using Firebug but couldn’t figure it out.

Here’s a link to the site/page…

The homepage has a ‘jQuery 2’ Slider which transitions through selected Posts.

I’ve also created a stand alone Post if that helps…

The CSS class that controls the appearance of the post titles is:

.post-title {
font-size: XX;
}

You can use percentage or px or em for font-sizes.

See the Codex on CSS and fonts for more info.

Also, be VERY sure to use a Child Theme when making changes to your theme.
