If you’ve ever tried to get to grips with responsive web design, you’ll know firsthand that it can be frustrating. Making sure your site looks great on just about every device is a daunting task. What’s more, being uncertain about how your site’s design will appear on a particular device could end up with bounced visitors. CSS media queries are a simple way to help create a responsive website.

SimpleCSS is an online tool that generates media queries for you based on your breakpoint or platform, and in this post we’ll show you how you can generate them in three clicks. To round up, we’ll also show you how Divi implements media queries out of the box.

An Introduction to CSS Media Queries

CSS media queries are a cornerstone technology of responsive web design. The CSS @media tag is used to set style rules based on different media types and devices. In simple English, media queries evaluate the capability of the device that is accessing your web page, and checks for its properties. These generally include:

  1. The width and height of the viewport.
  2. The resolution of the device.
  3. The orientation of the device.

Responsive web design focuses on adapting your site to be used on different devices. For instance, there’s a significant difference in user experience between a visitor using a mouse to navigate through your site, versus a touchscreen. Media queries enable web developers to bridge the gap in their site’s design:

Rewriting your site’s code to cater to each of the hundreds of devices that access your website simply isn’t feasible. Media queries work by using the same underlying HTML code, adjusting to the device’s screen size and orientation dynamically based on simple rules.

CSS3 enables web developers to define styles based on the device’s page width. Since the device’s page width correlates with its size, developers can essentially define different layouts for devices of various screen sizes by simply adding conditional rules in media queries. Some of the most commonly used expressions used for writing conditional rules are min-width, max-width, and orientation.

In a nutshell, media queries basically find out how big the device’s screen is, then apply some specific CSS to that screen size.

Benefits of Using Media Queries

The key benefit of using media queries is that your website is easily viewable by everyone, regardless of the device they’re using. From a technical perspective, media queries are compatible with all major browsers, and could potentially help your site rank better in search engine results. Some additional benefits of using media queries are:

  • A potential improvement of performance on mobile devices.
  • They enable you to create a mobile-first responsive design.
  • They provide a potentially better user experience to visitors.
  • The ability to display device-optimized versions of your site.

Media queries should ideally be used every time you need to make a particular page element responsive. For instance, if your site is split into a three-column design, chances are it’s not going be readable on a smaller screen such as a smartphone. Media queries enable you to change the layout to a one-column design for smaller screens.

Introducing the SimpleCSS Tool

Of course, creating all of these media queries can quickly become a pain. SimpleCSS is an incredibly useful tool for generating them, helps to take all of the heavy lifting out of targeting specific devices, and negates messing around with conditional expressions. Let’s take a look!


Interface of the SimpleCSS tool.

As the name suggests, SimpleCSS is an easy-to-use tool that enables web designers and front end developers to generate media queries for specific devices. Once you select a device, the tool outputs a media query tailored to that particular device, which can then be pasted into your CSS files. SimpleCSS also generates media queries based on breakpoints.

Key Features:

  • Enables you to start from two different approaches – mobile-first and desktop-first.
  • Enables you to select a general device to generate queries for.
  • Offers media queries for 286 different devices.

How to Generate Media Queries Using SimpleCSS (in 3 Clicks)

Now we’ve looked at what media queries are, and the tool that makes creating them simple, let’s show you how to generate media queries in only three clicks!

Step #1: Select Your Approach

The first step in choosing your media query is to decide on an approach for your responsive design, and you’ll need to select from Mobile First or Desktop First:

Radio buttons to select browser breakpoints.

If you’re struggling to choose, here’s the skinny on what both mean:

  1. Mobile First: This approach puts the focus on mobile devices, enabling you to optimize your display for those first, before larger-screened devices.
  2. Desktop First: This approach is designed to make your site look good on larger-sized screens at the expense of smaller ones.

Next, you’ll need to choose a device type.

Step #2: Specify the Device Type

Once you’ve selected your approach, the next step is to pick from one of five different breakpoints – Small Phone, Smart Phone, Tablet, Laptop, and Desktop. This is simply the points at which your site’s changes to provide an optimal layout for the reader’s device:

This step is simple – just click whichever device you’d like to generate media queries for!

Step #3: Copy the Media Query

Once you’ve selected a device, a modal pop-up will appear containing your media query. From here, simply copy the code and paste it into the appropriate place in your CSS file:

How to Generate Media Queries For a Specific Device Using SimpleCSS

Generating general media queries is fine as a general approach, but what if you need to generate them for a specific device? Let’s show you how to do it – again in three clicks!

Step #1: Specify Your Device’s Operating System

Firstly, select the operating system of the device you’d like to generate media queries for. SimpleCSS supports iOS, Android, and Windows. As a bonus, you can also generate media queries for the screen you’re currently using!

Step #2: Select Your Device

Once you’ve selected your operating system, you’ll need to filter down the device options available. There are 286 different devices supported in SimpleCSS, and if the selections are a little overwhelming (especially for Android devices), you can use the search bar to narrow the choices down:

Step #3: Copy the Media Query

Once you click on the relevant device, you’ll once again be presented with a modal pop-up containing your generated media query, ready to be copied into your clipboard:

That’s all there is to it! You’ll never again have to manually create media queries, and your sites can be one step closer to becoming responsive.

Responsive Design and Divi

Our Divi theme already implements a responsive design based on media queries, meaning you may not need to generate them yourself. Check out this example to see what happens when you resize your browser’s window:

The theme adapts dynamically to the changing window size – which is the premise behind using media queries. As the width of your browser window decreases, the layout changes ensuring that the content is still easy to read. The three different breakpoints take action, and give Divi’s layout a fluid-like feel. At different breakpoints, the media query that is triggered takes effect, and the layout of the design changes accordingly.


If your website isn’t responsive, it will likely suffer in search engine rankings. One way to ensure your site remains responsive is by using media queries. While they may have been difficult to create in the past, generating them is quick and simple with a tool such as SimpleCSS.

Let’s recap how you can generate media queries in three clicks:

  1. Select your approach and device, or your desired operating system.
  2. Specify the appropriate device type.
  3. Copy the generated media query, and paste it into your CSS file.
