Change font in sidebar

How can I change font and size, and move to center “Align to center” (The title of widgets).

I could change font and size inside? of widget = using the code below

.widget a {
font-family: Futura;
font-size: 14px;

However, what I want to change is a title? of the right sidebar.
Thank you in advance.

One more font question.

How can I change font/size of the title of post?

You might want to change font for regular text in sidebar as well. Currently you have applied CSS to URLs but not text itself. So here goes your optimized code and widget title centering and size adjustments.

.widget a, 
.widget {
    font-family: Futura;
    font-size: 14px;
.widget-title {
    font-size: 24px;
    text-align: center;

This code will help you to change fonts for Post title.

.entry-title, .entry-title a {
    font-family: Futura;

It worked! I really appreciate your help, answering such basic questions!
