By default, the design already has cursive font (it’s only visible on the live view, not when you edit the page).
To apply cursive font like in my demo, follow these steps :
First, select the text that you want to turn into cursive font. Put your cursor and click your mouse on the text block. If you click correctly, you will see “Style” tab on your right panel. Click “Advance typography“, browse the Font Family, the cursive font for the theme will be on the top list (scroll up to the first item on the drop down). See image bellow.
After you click preview (preview the actual page), if the font size is too small, you can increase it. The steps are similar to the previous one. You can also play around with other settings.
