Q:

Reduce font size

I need your assistance regarding my problem. In fact, I've tried to change the slider's font size on my website : http://compil2rai.com/ on the style.css file, but the changes are not taken in account. Any help ?

A:

Not a WordPress question, but add the following in your stylesheet:
.featured-text h2, .featured-text h2 a {
    font-size: 24px !important; /* set font size */
}

In the future, simply Inspect Element to find which class or tag to style.
