Web Design Explained
What Does a Website Designer Do vs a Web Developer?
Two roles, one website. Here is what each one actually does, the skills and tools they rely on, and how they work together to turn an idea into a site that looks right and works properly.
Ask five business owners what a web designer does and you will get five answers, most of them along the lines of “making it look nice”. That is part of the job, but only part. Ask what a web developer does and the answers get vaguer still, usually something to do with code.
The confusion is understandable, because the two roles overlap and plenty of people do a bit of both. It matters, though, when you are hiring. Knowing who does what helps you brief the right person, judge quotes fairly and understand why some agencies keep both roles under one roof. This guide breaks down the designer’s job, the developer’s job, the skills and tools behind each, and how the two work together on a real project. If you want the short version, our web design and web development pages explain how we handle both.
The Role of a Website Designer (UI/UX)
A website designer plans how a site looks, feels and guides people towards an action. That work has two halves: user experience (UX), which is the structure, page flow and journeys visitors take, and user interface (UI), which is the layout, typography, colour, imagery and interactive elements they see and touch.
Design starts long before anything looks pretty. A designer has to understand who the site is for, what those people are trying to do and what the business needs from the visit, then shape every page around that. On a typical project the designer delivers five things.
What the Designer Delivers
Research and Site Structure
Who the visitors are, what they need and how the pages should be organised. This becomes the sitemap and the main user journeys, such as searching for a service and requesting a quote.
Wireframes
Simple skeleton layouts that show where headings, text, images, buttons and forms will sit on each page before any styling is applied.
Visual Design Mockups
The wireframes brought to life with your brand: typography, colour palette, imagery, spacing and the overall tone of the site, presented for desktop and mobile.
Prototypes and Revisions
Clickable previews that let you test how the site will feel, followed by rounds of refinement based on your feedback.
Design System and Handover
Reusable components, spacing rules and exported assets, packaged so the developer can build exactly what was approved.
The best designers think about conversion the whole way through: where the enquiry button sits, how the form feels on a phone, and whether a visitor can find the one thing they came for without hunting.
The Role of a Web Developer (Front-end/Back-end)
A web developer turns approved designs into a working website. Front-end developers build what visitors see and interact with in the browser. Back-end developers build what happens behind the scenes: the content management system, databases, forms, integrations, hosting and security.
On small business projects one person often covers both sides, sometimes described as a full-stack developer. Either way, the work splits into two areas.
Front-end development covers:
- ✓ Writing the HTML, CSS and JavaScript that make up each page
- ✓ Making layouts responsive so they adapt to phones, tablets and desktops
- ✓ Building menus, sliders, accordions and other interactive elements
- ✓ Optimising images, fonts and code for fast loading
- ✓ Checking accessibility and cross-browser behaviour
Back-end development covers:
- ✓ Setting up the content management system, usually WordPress for small business sites
- ✓ Configuring forms, email routing, bookings and payment or CRM integrations
- ✓ Managing databases, hosting, SSL certificates and backups
- ✓ Hardening security and keeping plugins and core software updated
- ✓ Handling redirects and technical SEO settings at launch
Developers are also the people you call when something breaks: a form that stops sending, a plugin conflict after an update, or a page that has slowed to a crawl. That is why ongoing support is part of a well-run website, not an afterthought.
Key Skills and Tools for Each Profession
The two roles draw on different skill sets and different toolkits. Here is what each one typically needs to be good at, and what they use day to day.
Designer Skills
Visual hierarchy, typography and colour theory, layout and spacing, user research and journey mapping, wireframing and prototyping, accessibility basics, and the ability to explain design decisions in plain language.
Designer Tools
Figma, Adobe XD or Sketch for wireframes and mockups, Photoshop and Illustrator for imagery and graphics, and analytics or heatmap tools to see how visitors actually use the pages.
Developer Skills
HTML, CSS and JavaScript, a server-side language such as PHP, responsive coding, performance optimisation, security practices, version control, debugging and the technical side of SEO.
Developer Tools
A code editor such as VS Code, GitHub for version control, WordPress and its page builders, browser developer tools, staging environments for safe testing, and speed testing tools such as PageSpeed Insights.
“A designer decides what the button should say, where it sits and how it feels to tap. A developer makes sure it works on every device and sends the enquiry to the right inbox.”
How Designers and Developers Work Together
On a well-run project the two roles are never far apart. There are four points in every build where the handover matters most.
Discovery and Structure
Both roles join the first conversation. The designer maps goals and user journeys while the developer flags technical needs early, such as bookings, e-commerce or integrations with other systems.
Design and Feedback
The designer produces wireframes and mockups. The developer reviews them for feasibility and performance before the client approves, so nothing is promised that cannot be built well.
Build and Quality Checks
The developer builds the site from the approved designs. The designer reviews spacing, typography and responsive behaviour, and both test on real phones and desktops.
Launch and Improvement
The developer handles hosting, launch and backups. The designer keeps refining pages based on how visitors behave, and both feed into ongoing updates.
