How to Customise an Astro Template

Customise an Astro template by identifying where the package stores shared settings, page content, components and styles. Replace the example content first, adjust the design system next and change structural features only after you understand how the existing pages work.

This order reduces accidental inconsistency. A homepage can look finished while its footer still names the sample business or its contact form points to a demonstration destination. Treat customisation as preparing a usable website, not only changing colours.

Begin with a working copy

Complete the initial installation and build the original package. Keep that baseline available through version control or a separate untouched copy.

Write a short content map: homepage, about, services, contact and any articles or product pages. For each page, identify its source file or collection entry. Also locate navigation, footer and metadata settings.

If the same telephone number appears in several source files, decide whether it should become a shared setting before editing every copy. Repeated information creates future maintenance work, particularly when a business changes contact details or service areas.

Replace the identity and claims

Update the business name, logo, contact information, address where applicable and the site’s public domain configuration. Search the source for example names and sample email addresses so hidden remnants are not missed.

Replace testimonials, client logos and performance statements with material you can support. If you do not have a real case study, use a clear service explanation instead of presenting a fictional project as evidence.

Review metadata separately from visible text. Browser titles, descriptions, social previews and image alternative text can retain demo wording even after the page body has changed.

Use the existing style system

Look for central colour, type and spacing variables. A package might define these in a global stylesheet, a framework configuration or a dedicated theme file. Learn that arrangement before adding overrides in many unrelated components.

For a project using CSS custom properties, a deliberately small starting change could be:

:root {
  --brand: #19505c;
  --surface: #f5f8f7;
  --text: #172a2e;
}

These names are illustrative. They change the website only if its styles actually use them. Search for the existing variables and edit the real tokens instead of assuming that a pasted snippet controls an unfamiliar package.

Astro supports both scoped and global styling, described in its Astro 5 styling guide. A local style change may affect one component, while a global rule can alter many pages. Keep that scope in mind when reviewing the result.

Adapt the layout to real content

Replace short demo headings with your actual wording before fine tuning spacing. A service title that wraps onto three lines can expose a card layout that looked balanced with two-word examples.

Test long navigation labels, missing optional images and a paragraph longer than the sample. Prefer layouts that handle these normal variations instead of forcing every content item to match an arbitrary visual length.

Change one repeated component when the same design appears across the site. The components and layouts explanation helps identify when a shared edit is appropriate and when a page-specific change should stay local.

Replace images deliberately

Check the rights to both included and replacement assets. Product previews may contain images that are licensed differently from the template source, so read the actual asset notices.

Choose crops that preserve the relevant subject at mobile and desktop widths. Add meaningful alternative text for informative images, and treat decorative images according to their role. Avoid describing an image with keywords unrelated to what it communicates.

After replacement, inspect the rendered output. A large source photograph can look acceptable on your own connection while creating an unnecessarily heavy page for visitors. Evaluate the actual file dimensions and delivery behaviour rather than judging only sharpness.

Connect actions to real destinations

Update buttons that lead to enquiries, booking tools, application login or external documentation. A visual button labelled “Book a call” should have a deliberate destination and a usable alternative contact method where appropriate.

Test form submission through to receipt, including invalid input and failure states. If an integration is not ready, do not leave a convincing success interaction that silently discards a request.

Also review privacy information against the services you actually enable. Analytics, embedded media and third-party forms can change the data flow compared with the untouched package.

Check the full page family

Select representative routes: the homepage, a long service page, an article, a listing and a contact page. Test them with a keyboard and on a narrow screen after substantial design changes.

Check heading order, focus visibility, readable text contrast and whether menus can be opened and closed. A template’s original behaviour can be affected by changes to spacing, colours or hidden elements.

The InvoicePilot listing offers one example of a product with a defined marketing purpose. Evaluate its current page inventory against your actual service rather than retaining sections simply because they look polished.

Prepare a release check

Build the customised project, preview its production output and inspect important routes directly. Verify links, contact delivery, metadata and any shared settings on more than one page.

Keep a concise editing note for the next maintainer: where content lives, how a build runs and which services need separate accounts. The Astro website templates guide places these edits within a maintainable launch workflow.
