Motivation

A mobile-first approach is important in web development because it prioritizes the needs of mobile users, who now make up a significant percentage of internet traffic. By designing for mobile first, you can ensure that your website is optimized for smaller screens and slower network connections. Here are some reasons why a mobile-first approach is important:

• Mobile usage is increasing: According to Statista, in 2021, mobile devices accounted for 54.8% of global website traffic. This means that more than half of all website visitors are accessing the internet from mobile devices. By designing for mobile first, you can ensure that your website provides a good experience for the majority of your users.
• Smaller screen sizes: Mobile devices typically have smaller screens than desktop computers, so it's important to design for those smaller screens to ensure that your website is usable and easy to navigate. By designing for mobile first, you can ensure that your website works well on smaller screens and then scale up to larger screens as needed.
• Slower network connections: Mobile devices are often used on the go and may have slower network connections than desktop computers. By designing for mobile first, you can optimize your website for faster loading times and ensure that it doesn't require too much data to load.
• SEO benefits: Google's mobile-first indexing means that the mobile version of your website is used for ranking and indexing purposes. By designing for mobile first, you can ensure that your website is optimized for SEO and that it ranks well in mobile search results.

In summary, designing for mobile first is important because it ensures that your website is optimized for the majority of your users, provides a good user experience on smaller screens, loads quickly on slower network connections, and is optimized for SEO.

Examples

Let specify the desktopWidth attribute.

mobileFirst({ desktopWidth: 600 }),

/* desktop first */
.blue {

  background: peru;
}

@media (max-width: 600px) {
  .blue {
    background: blue;
  }
  .red {
    background: red;
  }
}

/* mobile first */
.blue {
  background: blue;
}
.red {
  background: red;
