Adding custom CSS
Add your own CSS to Goodnews without editing the theme files directly.
For small style tweaks, WordPress's built-in Additional CSS panel is the simplest option — no file editing and no risk of losing changes on update.
Using the Customizer
- Go to Appearance → Customize → Additional CSS.
- Add your CSS rules.
- Changes preview live and apply as soon as you publish.
.mom-post-meta {
font-size: 13px;
}

When to use a child theme instead
The Additional CSS panel is fine for small tweaks. For a large stylesheet, or if you also need to change PHP templates, use a child theme instead — see Using a child theme. It keeps your styles in version-controllable files rather than the database, and lets you override templates as well as CSS.
