Centering "What We Do"

In your custom CSS area or child-theme CSS, you can add one of the following:

.home-intro h4 {
    text-align: center;
}

or you can also do

#intro h4 {
    text-align: center;
}

Thanks, that fixed it

1 more question regarding it. How do I increase the font size for it?

Just add font-size to that code, like this:

#intro h4 {
    text-align: center;
    font-size: 24px;
}

Change the number as you see fit.

Seems fixed, marking as resolved.
