Cross Browser Compatibility


The web growth has resulted in multiple technologies to build this web ecosystem and various tools, like web browsers, to access and interact with this content. More users, more devices, more platforms, more browsers, and ultimately more ways to view your website. As a web developer or product manager, you need to make sure that your website is compatible with every technology with the help of browser compatibility testing.

Your users can be anyone, and they might be using any browser. You cannot let your bias towards a browser or a browser resolution affect your product. It is entirely possible that browsers that we respectfully ignore while developing can be a favorite browser to our target users, affecting your product’s cross browser compatibility!

Get started with Cross Browser Compatibility, What is Cross Browser Compatibility and Why we need it?

Understanding how a browser works is highly beneficial for a web developer before using the developer console and building an interactive web application as every browser is developed differently. Hence, it renders differently

How Do Browsers Work?

Cross browser compatibility bugs are inevitable for any web project irrespective of whatever platform they are using for development. And most importantly, they keep creeping in at every iteration. To understand those issues in a deeper sense, it is crucial to know how browsers work, structure, process flow, DOM & CSS object model construction & more!

All About Browser Engines

Have you ever pondered upon the cause of website discrepancies on different browsers? Why would your website look different from one browser to another? What lies at the center of these browser incompatibility issues?

The answer is Browser engines. Check here to know All About Browser Engines.

Since its first inception, JavaScript has been the main culprit behind cross browser compatibility issues, as it was the fastest-growing technology of the time. So fast that most browsers had to catch up to give support. However, after new HTML5 standards, JS got a new partner in causing havoc. Since HTML and CSS are simpler languages, people misunderstood them as not the culprit for cross browser compatibility issues. Does this hold true?

Check out our blog on Cross Browser Compatibility issues to learn more.

Now that you are well acquainted with the concept of Cross Browser Compatibility, the functioning of browser engines, and the need to find cross browser compatibility issues. It is time to dig deeper into the most common problems associated with cross browser compatibility.

Issues With JavaScript

Problems with JavaScript code majorly occur when developers come up with features in web pages that do not support old browsers or due to incorrect implementation of browser sniffing code. Unless a standard mechanism of processing JavaScript (or other scripting languages) is implemented, cross-browser compatible issues with JavaScript can continue to persist.

Issues With AngularJs

A web application developed in Angular 4 sometimes may include animations. The web library used for animations, web-animations.js, is especially notorious for giving Safari 10 and lower version errors. So, Angular 4 browser compatibility is something you don’t want to miss out on.

Issues With WordPress Websites

Out of the box, WordPress is not adequate to power custom business needs. To make up for functionality gaps, webmasters use third party themes and plugins, along with custom CSS and JS codes. Developers use a wide range of APIs, features, and technologies to fulfill the requirements. And that’s from where WordPress compatibility issues start!

Check out our WordPress Compatibility issues guide here to learn more.

Issues With Typography

Sometimes amidst using beautiful fonts, we forget to take care of typography compatibility. Font formats that we use are not always compatible with every browser. If a font is looking beautiful in Mozilla doesn’t imply that it will look the same in Opera, too, because maybe Opera doesn’t support the underlying tag itself. How do you handle such issues?

Jump on to this guide on Typography Compatibility to know more.

Issues With Variable Fonts & Static Fonts

Explore what variable fonts & static fonts are, their advantages and disadvantages. You will also learn how to use them in your web pages and how to add necessary static font fallbacks for unsupported browsers by leveraging the power of cross browser compatibility tools.

Variable Fonts

Issues With Vertical Text Orientation

The necessity for vertical text-orientation might not seem evident initially, and its use is somewhat limited solely as a design aspect for web pages. However, many Asian languages like Mandarin or Japanese scripts can be written vertically, flowing from right to left or, in the case of Mongolian, left to right. Another common use of vertical text-orientation can be in table headers. This is where the text-orientation property becomes indispensable.

Check out why Vertical Text Orientation is a nightmare for cross browser compatibility?

Issues With Form Input Types

With the rollout of HTML5 in 2014 and web forms 2.0, 13 new form input types were introduced that supercharged HTML Forms. As good as these newly introduced form input types were, they posed a plethora of cross browser compatibility and consistency issues, which in some cases could dampen user experience or lead to faulty form submissions.

To know more about it, go through our blog on cross browser compatibility issues with Form Input Types.

Issues With HTML5 Input Fields

With the introduction of HTML5 came new types in the input field to make user and developer work more straightforward than ever. Although many types have been introduced in HTML5, all of those are not “so important” in terms of cross browser compatibility as it might seem.

Check if your HTML5 Input Fields are cross browser compatible.

Issues With Emojis

Each update in browsers or apps brings in several enhancements in the attribute and modifications in the codes, which was absent in the prior versions. This creates a problem when you are using an older version of the application. An emoji might appear as an empty box or something weird. The reason for this incompatibility is that there are many browsers on board, and each has a different way of rendering the fonts and images.

Cross browser compatibility is essential. Very important. We have established that fact so far. The next step is how to make cross browser compatible websites? How can we make sure that our website gives a smooth and seamless user experience across all browsers that your target audience may have access to, be it Firefox, Chrome, or Edge?

Creating Cross Browser Compatible Website

While developing a website, you usually use a combination of Javascript, CSS, and HTML, with CSS3 and HTML5 being the latest. If you’re also developing your website on these technologies (don’t mind the latest or not 😉), you might need to take care of some points to make your website suitable for every browser.

Cross browser compatibility testing, as you know now, is a process where you test your website over multiple numbers of browser & browser versions running on different operating systems. This is done so to realize the cross browser compatibility of a website or a web app when accessed across a variety of browsers. If your web app isn’t cross browser compatible, then not only would you be missing out on potential leads, but your customer retention could also suffer.

Browser Differences To Look Out For

When it comes to a web application, before it goes into production, the developer must make sure that it works properly in all browsers. The end-user should experience a fully functional site that can handle all critical functionalities irrespective of the browser or device used by the end-user. Do you know what browser differences to look out for? Can those differences be causing breakage in different browsers?

Go through this comprehensive guide on the crux of Cross Browser Compatibility.

Creating Browser Compatibility Matrix

When you have hundreds and thousands of devices and browsers available, you need to formulate a proper cross browser testing strategy to ensure your users get a seamless browsing experience on all devices. Based on your audience, geo, and usability, you need to formalize a proper browser matrix covering all the browsers based on their usability. This formalized list of browsers is called a 'Browser Matrix.'
