Hi Alberto,

first of all - we are glad you like our theme.

As you probably noticed the font size itself is not provided by the Custom Fonts plugin. It provides font variants (font family + font weight) but once you have the fonts in place it is easy to set the font size attribute with custom CSS.

This is also useful in Typography: elements for example in main title category have different font sizes; therefore you may want all the elements in this category to have the same font family but now the same font size

if you indicate an element you want to change the font size (screenshot would also help) we can help you with CSS and give you instructions on how to change for the others.

Hi Alberto,

Step by step

- right click in browser and then select Inspect Element. The Dev Tools window opens and the selected element highlighted

- scroll down until you find the element or the immediate parent element that sets the font size:

in our case .hero-subtitle

https://prnt.sc/weRXFb9oIjA6

you can see it has 14px in size

Therefore to increase it for example to 20px we add in customizer -> additional CSS

.hero-subtitle {
    font-size: 20px;

}
