Total unique simple selectors: 2

4. Statistics (in a nutshell)

Sample CSS:

.foo {
    p: v
}
.foo, .bar + .car {
    p: v
}

Here:

• .foo and .bar + .car are so called simple selectors;
• .bar + .car is selector group.

So in resulting statistics you will see:

• 2 selector groups — .foo and .foo, .bar + .car;
• 3 simple selectors — .foo, .foo and .foo, .bar + .car;
• 2 unique simple selectors — .foo and .bar + .car.
