<h1>A Guide to Quickly Testing CSS Fallbacks</h1>

Quickly Testing CSS Fallbacks

It’s not always easy to know if a fallback solution for your CSS will work on all browsers and devices. Fortunately, there are a few techniques that can quickly test the effectiveness of your fallback solution.

Test on Multiple Browsers

The first step is to make sure that you’re testing on multiple browsers. Your code may look fine in Chrome, but fail in IE or Firefox. Be sure to check in each major browser to make sure your CSS fallback solution works properly. If possible, use a tool like BrowserStack that can test across a variety of browsers in one place.

Use a Grid System

A grid system can be a great way to quickly test out a variety of fallback solutions. By using a grid layout, you can easily see how each element is responding whenever you make a change to the code. This makes it easy to tell when something isn’t working as expected. Tools like Flexbox and Bootstrap make building and testing grid-based layouts easier than ever.

Try Different Screen Sizes

Mobile devices come in a variety of shapes and sizes, so it’s important to test your fallback solution on them as well. The easiest way to do this is to use an online simulator like Responsive Design Checker. This tool allows you to quickly switch between different screen sizes and see how your design looks across devices. Take the time to thoroughly test any complex fallback solutions on a variety of devices.

Employ CSS Preprocessors

CSS preprocessors like SASS and LESS make it easy to quickly test out different fallback solutions. With preprocessors, you can set up variables and mixins that make it simpler to adjust the design as needed. These tools also let you quickly set up fallback solutions that can be tested efficiently. The ability to save time when switching between different fallback solutions makes preprocessors a great tool for quickly testing out CSS fallbacks.
