Let’s take a traditional “fixed” website.  When viewed on a desktop computer, for instance, the website might show three columns. But when you view that same layout on a smaller tablet, it might force you to scroll horizontally, something users don’t like. Or elements might be hidden from view or look distorted.  The impact is also complicated by the fact that many tablets can be viewed either in portrait orientation or turned sideways for landscape view.

On a tiny smartphone screen, websites can be even more challenging to see. Large images may “break” the layout. Sites can be slow to load on smartphones if they are graphics heavy.

However, if a site uses responsive design, the tablet version might automatically adjust to display just two columns. That way, the content is readable and easy to navigate. On a smartphone, the content might appear as a single column, perhaps stacked vertically.  Or possibly the user would have the ability to swipe over to view other columns.  Images will resize instead of distorting the layout or getting cut off.

The point is: with responsive design, the website automatically adjusts based on the device the viewer sees it in.

How Does Responsive Web Design Work?

Media such as images is also resized relatively. That way an image can stay within its column or relative design element.

Mouse v. touch: Designing for mobile devices also brings up the issue of mouse versus touch.  On desktop computers, the user normally has a mouse to navigate and select items.  On a smartphone or tablet, the user mostly is using fingers and touching the screen.  What may seem easy to select with a mouse, may be hard to select with a finger on a tiny spot on a screen. The Web designer must take “touch” into consideration.

Graphics and download speed: Also, there’s the issue of graphics, ads and download speed. On mobile devices, it may be wise to display fewer graphics than for desktop views so that a site doesn’t take forever to load on a smartphone.  Larger ad sizes may need to be exchanged for smaller ads.

Apps and “mobile versions”:  In the past, you might have thought about creating an app for your website — say an iPad app or an Android app.  Or you would have a mobile version specifically for BlackBerry.

But with so many different devices today, it’s getting harder to create apps and different versions for every device and operating platform.

Why Small Businesses Need to Switch to Responsive Web Design

More people are using mobile devices. A recent Pew study 77 % of Americans now own smartphones in 2018 which is up from just 35% in Pew Research Center’s first smartphone ownership survey carried out in 2011.

Check your traffic and you might just be shocked at how many visitors are getting to your website through mobile devices.  (In your Google Analytics, select “Audience” on the left side, then “Mobile” to see what proportion of traffic is from mobile devices. You can even drill down to see which devices are sending the traffic.)
