Introduction

As a developer, one of your responsibilities is to build responsive websites that fit all devices' screens. But the big dilemma is deciding which approach to start developing first, either mobile-first design or desktop-first design.

In this post, you'll learn about both approaches, their pros and cons, and when to choose either of the approaches to meet your project specification and modern responsive web development standards.

What is Mobile-First Design?

Mobile-first design is an approach in which development starts with smaller screens, such as smartphones, and then progresses to larger devices. This technique emphasizes progressive enhancement, beginning with a simple, functional design for mobile users and gradually increasing features and complexities as the screen size rises.

This approach assures that your website is mobile-ready, with seamless navigation, touch-friendly components, and faster performance on mobile devices. It also adheres to current trends such as mobile-first indexing, in which search engines emphasize mobile-optimized content in their ranks.

To implement a mobile-first design, you can:

1. Use some mobile-first CSS frameworks like Tailwind CSS or Bootstrap, which provide prebuilt classes and components tailored for responsive layouts.
2. Define media queries in your CSS file to handle smaller screens, such as:

@media only screen and (max-width: 768px) {

/* Styles for smaller devices */

}

By adopting this approach, you've ensured that mobile users have a smooth and effective experience, setting the foundation for a scalable and responsive design.

What is Desktop-First Design?

Desktop-first design is a development approach that focuses on developing larger screen layouts such as desktops and laptops first. Once the desktop layout is fully developed, the design is redeveloped (scaled down) to fit smaller screen devices like smartphones and tablets.

Starting with this approach and then scaling down means you're gracefully degrading the complex large-screen UI(User Interface) layouts and features that may disrupt the UX(User Experience) on smaller screens by simplifying or removing certain designs as they transition from desktop to mobile.

Using CSS attributes such as flex boxes, grid, percentage %, etc, which are not in an enclosed media query option makes the styling valid for all screen sizes, then you can scale down by specifying how the CSS attributes will affect the layouts on smaller screens in the enclosed media query

@media only screen and (max-width: 768px) {

/* Styles for smaller devices */

}.

You can also use CSS frameworks like Tailwind CSS and Bootstrap to achieve the mobile-to-desktop transitioning but you need to specify the screen breakpoints–"md, lg, xl".

The desktop-first approach is suitable for applications or sites that are mainly used on desktop/laptop computers, such as inventory management apps, superstores check-out apps, business tools, or design-heavy platforms.

So, what's the difference between these two approaches?

Differences Between Mobile-First and Desktop-First Design.

Both mobile-first and desktop-first design approaches aim to create responsive and user-friendly experiences, but they differ in terms of content prioritization, UI/UX, and design scalability.

Mobile-First:

This focuses on simplicity and usability, where the essential features and functions are accessible on smaller screens and simplified navigation to enhance usability on touchscreens while keeping the design minimal.

Desktop-First:

This approach is for complex layouts, it emphasizes more on complex elements and features like mouse-and-keyboard interactions that may not translate well on smaller screens.

What Are The Best Practices for Implementing Mobile-First or Desktop-First Design?

In this section, you'll get to know some best practices for implementing either of the approaches.

In Mobile-First Design, you should start developing important features that fit small screens and add more as you scale up. Use media queries, flex, grids, and flexible layouts to handle different screen sizes. Also, test tap targets to ensure buttons and links are easy to use on touchscreens.

Desktop-First Design.

This approach focuses on creating attractive designs with content scalability in mind. Make sure that you consider browser compatibility and the layouts should be optimized for mouse and keyboard users. Also, Create simplified navigation and interactions when scaling down for mobile, you don't want your users looking lost when using your design.

What Are the Common Mistakes To Avoid When Using Either Mobile or Desktop First-Design?

Failing to test the UI layouts across devices can lead to unexpected design and responsiveness issues. Also, neglecting web accessibility can exclude users with disabilities.

When to Choose Between Mobile or Desktop First-Design

When you want to choose between mobile-first and desktop-first deaign approach, you should consider your audience based on the following:

1. If your users are mostly on mobile, e.g. a food ordering app, a mobile-first design makes sense.
2. If your platform is primarily used on desktops, such as office tools, a desktop-first design might be better.
3. Consider factors like device capabilities, user behavior, and the types of features your application needs.

When the above is considered, you'll be sure of what approach to build and deploy first.

Conclusion

The choice between these approaches ultimately depends on your users and their primary devices, If you don't know, please carryout a survey.

For users with mobile (small screen), a mobile-first design ensures better engagement. Contrarily, if your application depends on advanced features for desktops, a desktop-first design might be the better start.

It's also important to consider performance, prioritize content, and ensure web accessibility.

By following this guide, you’ll know what approach to apply first when developing for your target audience.
