Thanks for the theme comment ??
This theme currently does not have a font size adjustment, but will consider adding a setting for this in the next update, as well for the pro version.
However, I know that does not help you right now, so you have the following options:
Option 1: If you use Jetpack, you can edit the theme’s stylesheet from the “Edit CSS” under the Appearance Menu by adding the CSS code you see further below….
Option 2: If you are not using Jetpack, you can install a plugin called Simple Custom CSS, and then you can also use the CSS code I gave you below.
Option 3: If you use a child theme, you can edit the child theme’s stylesheet…again with the code below.
The theme’s CSS for the font size in the “content area” is this:
#page {
font-size: 0.813rem;
}
To make it bigger for the content, this would be your custom CSS:
#page {
font-size: 0.875rem;
}
To find out what 0.875rem; is in pixels (which is 14px), you can find out from the link below, but you can make your font size whatever you wish. I would recommend using the rem value and not px (pixel).
