Reduce font size

I installed Sparkling recently. Everything is great and I wanna say thanks for that.
But there’s a little problem. The article title and ‘thought to’ font size is too large. How can I change this font size?
Look at this link
and the pictures.

Hi @juxiangchuan,

I hope you are well today and thank you for your question.

You can try achieving this by adding the following CSS code in the Custom CSS option of your theme on the below path.

Admin Area -> Appearance -> Customize -> Additional CSS

h1.entry-title {
    font-size: 24px;

h2.comments-title {
    font-size: 20px;

Best Regards,

Thanks a lot. It works really well now.

You are most welcome here :slight_smile:
