Change look/font size of Tabs descriptions

Is there a way to change thefont size of the tab descriptors? Here is what I have now, but I'd like to make them smaller so that they don't consume so much of the form real estate.

You can do it by injecting custom CSS codes in the Custom CSS option of the Form Tabs widget in your form.

Example, to make font-size 10px smaller in size.

.liContent {

font-size : 10px;

}

Thank you. How about the size of the tab itself? Can I make that smaller,
too?

Please try adding the next CSS codes to the Custom CSS of the form tabs widget

.tabs-list.default li {

    padding: 3px 10px;

}

Unfortunately this is the maximum numbers that can be used, otherwise the tabs will be overlapping in between if the px numbers will be more than.

Example result:
