You can customise a WordPress theme without coding in three ways: the Site Editor (Appearance, Editor) for block themes, the Customizer (Appearance, Customize) for classic themes, or a page builder such as Elementor. Change global styles first (colours, fonts, spacing), then the header and footer, then page templates and individual pages. Use a child theme only if you also need code changes later.
- Which tool you use depends on whether your theme is a block theme or a classic theme.
- Global styles keep the whole site consistent and save time.
- Changes made in the Site Editor, Customizer or Elementor survive theme updates.
- Keep a simple style guide: 2 fonts, 3 to 5 colours, consistent spacing.
- Check every change on mobile.
How do you know which customisation tool your theme uses?
Picture a coach who searches for “Customize” in her dashboard and cannot find it. Her theme is a block theme, so customisation lives in Appearance, Editor instead. Knowing which kind of theme you have saves a lot of confusion.
- Appearance, Editor visible: you have a block theme. Use the Site Editor.
- Appearance, Customize visible: you have a classic theme. Use the Customizer and theme options.
- Elementor installed: you can design pages, and with Elementor Pro, headers, footers and templates.
How do you customise a block theme with the Site Editor?
- Open Appearance, Editor and choose Styles.
- Pick a style variation if your theme offers some, as a starting point.
- Set colours: background, text, links, buttons, using your brand palette.
- Set typography: one font for headings, one for body text, readable sizes.
- Edit template parts: header (logo, menu, button) and footer (contact, links, copyright).
- Edit templates such as Single Posts, Pages and Archive.
- Save patterns for sections you reuse, like call-to-action blocks.
How do you customise a classic theme with the Customizer?
- Open Appearance, Customize.
- Site Identity: logo, site title and site icon (favicon).
- Colours and typography in the theme’s global settings.
- Header and footer builder if your theme has one (Astra, Kadence, Blocksy).
- Menus and widgets for navigation and sidebars.
- Homepage settings and blog layout.
- Publish, or schedule changes for later.

When should you use Elementor instead?
Elementor is ideal when you want pixel-level control of landing pages and a visual drag-and-drop workflow. Set Site Settings (global colours and fonts) first, then build headers, footers and templates in Theme Builder with Elementor Pro. Pair it with a lightweight theme such as Hello Elementor so you are not loading two design systems. Ready-made layouts can speed you up; see the best Elementor templates.
What design rules make a customised theme look professional?
| Rule | Why |
|---|---|
| Use two fonts at most | Cleaner look and faster loading |
| One main brand colour plus one accent | Buttons and links stand out |
| Consistent spacing between sections | Pages feel calm and organised |
| High text contrast | Readable for everyone, better accessibility |
| One clear call to action per section | Visitors know what to do next |
| Real photos, compressed | Trust and speed |
What if the theme cannot do what you need?
Try a block plugin or Elementor add-on first. If you need deeper changes, use a child theme with small code tweaks, or consider a custom theme. Choosing a better base theme from this 2026 list can also be quicker than fighting a limited one.
Frequently asked questions
Can I customise WordPress without coding?
Yes. The Site Editor, the Customizer and page builders like Elementor let you change colours, fonts, layouts, headers and footers visually.
Why can I not find Appearance, Customize?
You are probably using a block theme. Use Appearance, Editor to customise it instead.
Will theme updates erase my customisations?
No, not if you used the Site Editor, Customizer or Elementor. Direct edits to theme files are erased by updates.
Do I need a child theme?
Only if you plan to add custom code or edit template files. For visual changes, no.
Is Elementor better than the Site Editor?
Elementor offers more design control and widgets; the Site Editor is built in, lighter and improving fast. Both can produce professional sites.
