Course Using WordPress Themes

Customising with CSS

Going Beyond the Defaults Preview

A little CSS goes a long way

Even without being a developer, adding small bits of CSS lets you adjust the things themes do not expose as settings.

Where to add custom CSS

Appearance → Customize → Additional CSS\n# or (block themes) Site Editor → Styles → Additional CSS\n\n/* Example: round the images */\nimg { border-radius: 12px; }

How CSS works

  • selector — what to target (e.g. h2, .site-title, img)
  • property — what to change (color, font-size, margin)
  • value — the setting (red, 20px, 10px 0)
/* target the site title only */\n.site-title {\n  font-size: 28px;\n  color: #1a4b8c;\n}

Practical exercise

Use Additional CSS to make your heading colour match your brand, then preview the effect.
