Web design: how to make sure your website is responsive

Whether you’re walking down the street, riding the bus or eating dinner at a new restaurant, it’s become common to see those around you plugged into their phones or tablets. More often than not, people browsing your website are checking it out on their mobile device. But, what does this mean for how responsive your website actually is?
Having a mobile-friendly site that loads quickly and is responsive is important to how users interact with it. Not only will users appreciate it, but it affects how you rank on Google algorithms, meaning it will affect how many visitors your site gets in the first place. Curious how to make your website more responsive on all platforms? Read on!

Here’s how to make sure your website is responsive!

What exactly is web responsiveness?

Web responsiveness refers to how well a website adapts to different screen sizes, resolutions, and device orientations. A responsive website automatically adjusts its layout so users don’t need to zoom or scroll horizontally to view content. Text should remain legible, images should scale properly, and navigation should be easy—regardless of whether the user is on a smartphone, tablet, or desktop.
It's more than simply fitting your desktop layout onto a smaller screen. True responsiveness involves fluid design, flexible images, media queries, and a user-centric interface that adjusts dynamically to provide a seamless experience across devices.

How to test website responsiveness

One of the easiest ways to test the responsiveness of your website is to use your desktop browser. Try shifting and changing the browser window to new dimensions. What happens when you do this? If your site is responsive, the layout will transform to fit any size window. Another simple test to perform is by checking the same website on your smartphone or even on your television.
Try looking at the site in different devices or browsers, as it is important to bear in mind that what may look nice on a brand new iPhone 7 might not look the same on an older Android phone. Responsive design is something constantly evolving over time, and for this reason, your website may not look good on every single device immediately.
An emulator is another way you can test for website responsiveness. There are various tools online that can assist you in the process. These tools all work in different ways, and each one will monitor a different aspect of your site. For this reason, try out a few different ones and see what findings you come up with regarding your website's response levels. Also worth mentioning is that it is important to not rely on emulators alone.

Tools to help make sure your website is responsive

Since there are no standard website dimensions, and there are hundreds of devices on the market, your website should be able to conform to as many as possible. As mentioned, there are a few different tools you can use to check the responsiveness of your website. Below, we'll go over a few and list their key functions:
Responsively App
