Font Size Services Type A

Is it possible to change te font size of the Services Type A header?
And how and where can i do that? Please explain to me.
I am trying for days now… and without resulut so far

link to my website:


You can change the service title’s font size on the widget with this Custom CSS:

.service-title {
    font-size: 14px !important;

Add the above CSS to your Child Theme’s style.css or in case you haven’t setup a Child Theme already, then you can also use this plugin to add the CSS to it: so you will not loose the changes on theme updates.

Best Regards,
