Hello,
Please add this code to the Theme Settings > Custom CSS > Global to place the title in the center:
@media (min-width: 769px) {
body .cat-design-default .hover-mask {
text-align: center;
}
body .cat-design-default .wd-entities-title {
right: 0;
left: 0;
}
}
You can change the font size by means of the Advanced typography option, which allows you to choose the item from a drop-down or insert your custom CSS class. Please navigate to the Theme Settings > Typography > Advanced Typography.
You need to choose the Category title and set the size for the desktop: https://gyazo.com/622ef2414f52bdc30db25e630f33536d
