Website Features: AI, Mobile Layouts and Dark Mode

Reviewed 28 October 2026. This guide from No Brainer Creative was originally published in June 2025. It now focuses on choosing website features against a real customer task, rather than predicting which annual trends every business must adopt.

A useful feature has a clear job. It might help a customer find the right service, complete an enquiry or understand what happens next. AI assistance, responsive layouts and colour themes each need different decisions and checks. Adding one does not establish higher rankings, more sales or a better experience for every visitor.

Start with the job the website needs to do

Write down the route a customer should follow and the information needed at each step. For a service business, that might be reading the scope, checking genuine coverage and making an enquiry. For an online store, it could include choosing a product option and understanding delivery before checkout.

List the observed problem before selecting the feature. “Customers cannot find the booking link” is a more useful starting point than “we need an AI chatbot.” A clearer label or navigation change may solve the immediate problem with less complexity.

Agree what is included, who approves the content, what needs to connect and who will maintain it. Compare a targeted repair with a larger rebuild. A simpler-looking page is not automatically faster, and removing useful information to make a layout minimal can make the customer’s task harder.

Decide whether AI assistance has a useful role

An automated assistant may help with defined questions or guide a visitor towards an existing route. Start with the questions customers actually ask and the approved information available to answer them. It is not an essential feature for every website.

Define the answer and handover boundaries

Decide which topics the assistant can handle and when a person should take over. It should have a useful response when information is missing, an answer is uncertain or the request falls outside the agreed scope. An immediate automated reply is not proof that its content is accurate.

Keep service facts, prices and availability tied to approved sources. Do not let a conversational interface imply that it has made a booking, processed a payment or changed a customer record unless that action actually completed. A recommendation is different from a confirmed transaction.

Check the connected journey

For a hypothetical workshop website, an assistant might explain the services offered and link to an appointment calendar. That does not mean it can confirm which mechanic is available or diagnose a vehicle. The business should define the actual scope before deciding what to automate.

Plan tests for ordinary questions, missing information and the handover to staff. Agree how a conversation is recorded and who handles an exception. Our CRM and marketing automation service describes the wider forms, bookings and follow-up scope that can be discussed; any additional assistant needs its own agreed requirements.

Review responsive layouts through real tasks

A responsive layout adapts content to the available space. It still needs checking with the actual copy, images and controls. A phone preview of the first screen does not test the menu, long service content, form errors or checkout.

Google’s responsive design guidance explains adapting layout and content to the viewport. Use that as a technical starting point, then review the customer journey rather than treating β€œresponsive” as an all-device guarantee.

  • Read the main information at the relevant phone and desktop sizes.
  • Open menus and disclosures, and follow important links.
  • Check whether content or controls extend beyond the page width.
  • Review form labels, required fields and error states.
  • Record the device, browser, screen size and any untested parts.

Images, tables and long labels can behave differently from the rest of the layout. Check them where they appear, not just in a design mock-up. A lab performance test and a manual layout review answer different questions; neither proves that every customer can complete the task.

Treat dark mode as a theme choice

A dark colour scheme may suit a brand or a visitor’s preference. It is not a requirement for a modern website, and it should not be presented as a guarantee of comfort, longer visits or health benefits. Decide whether maintaining another appearance serves the project.

If both light and dark themes are offered, check the actual interface in each. Logos, photography, form fields, error messages, focus outlines and disabled controls may need more attention than the page background. Keep information understandable in either theme.

Agree how the choice is made and what happens when a preference is unavailable. Then test the controls and transitions. A dark background alone does not establish accessibility or lower resource use; those need their own evidence.

Keep typography and resource decisions practical

Choose fonts and spacing around the content people need to read. Limit unnecessary complexity, but do not assume that bold type, a minimal palette or a particular file format creates a fixed performance or conversion improvement.

Our typography, motion and colour guide compares those choices in more detail. It also separates measured resource delivery from environmental claims and distinguishes hosting checks from emissions estimates.

Before claiming an improvement, identify what changed and how it was assessed. A smaller image file, an accessible control and a hosting-provider statement are different pieces of evidence. Keep their scope clear instead of describing them as a general certification of the website.

Agree the checks before choosing the feature

Questions to settle in a website feature brief
FeatureWhat to verify
AI assistanceApproved answers, uncertain requests, staff handover and any connected action.
Responsive layoutsReal content, menus, forms and the important task on agreed screen sizes.
Colour themesReadable content, controls and interface states in each supported theme.
Resource changesThe affected files or loading behaviour, visual quality and the same customer route.

For forms and bookings, separate reaching the details form from submitting it, creating a record and receiving the expected notification. Plan any live submission test with the business, keep it identifiable and record what remains unverified. Do not use a customer’s details for an unplanned test.

Keep a rollback copy before changing an existing website. After the change, repeat the relevant task and note the result. Useful verification is more specific than “the website works”: it identifies the route checked, the observed outcome and any remaining limitation.

Questions about website features

Do we need AI to keep our website current?

No. Start with the customer problem and compare the proposed feature with a simpler route. Clear service information and a reliable enquiry process may be the immediate priority.

Does responsive design guarantee a better Google position?

No particular position follows from a layout label. Review usability and technical issues as part of the wider website and search work, and measure search visibility separately.

Should every website offer dark mode?

No. Consider the brand, audience, content and maintenance involved. If it is included, define the supported appearances and test the important controls and information in each.

Does a green-hosting claim prove the website is faster?

No. Hosting evidence and loading performance answer different questions. Compare the actual service, technical conditions and measured results rather than treating an environmental label as a performance test.

How do we prepare a useful feature brief?

Bring the current URL, the customer task, examples of the problem and the systems that must connect. Our website project brief helps organise the scope. The practical user-experience checklist can support the review of an existing site.
