With the internet ruling over our daily lives, creating a website is a must for businesses, start-ups, and individuals. But just building a website is not enough; you need to make sure it is functional and compatible with different browsers. Cross Browser Testing is the key to ensuring that your website functions equally well on different browsers, platforms, and devices.
Now, you might be thinking that a website is just a website, nothing too complicated, but the reality is different. Cross Browser Testing is a crucial aspect of web development, and if neglected, it can cause issues like poor user experience, decreased traffic, and increased bounce rates. But don’t worry, this is where this complete guide on Cross Browser Testing comes to play.
This article will take you through all the essentials of Cross Browser Testing, what it means, why it is important, and how to ensure your website is compatible with different browsers. But we don’t want you nodding off from boredom halfway through this article, so we’ve added a pinch of entertainment along with the technical jargon to make it informative and fun. So let’s dive into the world of Cross Browser Compatibility.
What is Cross Browser Compatibility?
As the name suggests, cross-browser compatibility refers to the ability of a website to function well on different web browsers, such as Google Chrome, Mozilla Firefox, Safari, Internet Explorer, etc. These browsers interpret HTML, CSS, and JavaScript code differently, which can cause web pages to display differently or not at all. Hence, Cross Browser Compatibility is crucial to ensure that your website is accessible and usable on any browser that your website visitor may use.
The key areas that can be verified during browser compatibility testing include page layout, navigation, color, graphics, multimedia (such as audio and video), content presentation, functionality, and accessibility.
Cross-browser compatibility is the magical support that allows websites and web applications to be flawlessly rendered by all browsers, like a master illusionist conjuring awe-inspiring tricks that mesmerize audiences. However, this feat comes with a unique challenge stemming from the ever-evolving nature of the digital medium itself.
Importance of Cross Browser Compatibility Testing
Cross-browser compatibility testing is of utmost importance in today’s digital landscape. Websites play a critical role on the internet, serving as the online representation of companies and businesses. Whether it’s an e-commerce platform or a corporate website, it acts as a virtual storefront or a reflection of the organization.
If a website faces display issues on major browsers that are commonly used by customers, it can lead to a negative user experience. This, in turn, can result in visitors losing interest and choosing not to engage with the site. It is crucial to address browser compatibility issues because visitors can access the site using various browsers and different versions of those browsers.
The usage statistics of web browsers vary across different sources and regions. However, in general, Firefox, Chrome, Safari, and Opera dominate the market share. Chrome holds the largest market share at over 79.5%, followed by Edge at 9.0% and Firefox at 4.6%.
Reaching a wide audience and effectively utilizing the web’s potential is challenging due to the diverse web client configurations used to interact with web content. This is why conducting browser compatibility testing is necessary. By identifying and addressing compatibility issues with web client configurations, we can provide solutions that ensure a seamless user experience across different browsers.
What Causes Browser Compatibility Issues?
The evolution of web browsers has led to different rendering engines and JavaScript engines being used, resulting in browser compatibility issues. Let’s consider some examples:
1. The Browser Wars
In the early days, Netscape Navigator dominated the browser market until Microsoft introduced Internet Explorer (IE) as a competitor. This led to the first browser war, where different browsers implemented their own features and non-standard coding practices. Websites built during this era often relied on browser-specific features or non-standard code, leading to compatibility issues when accessed on other browsers.
Example: Websites that heavily relied on Internet Explorer’s proprietary features might not display correctly in modern browsers like Chrome or Firefox.
2. Introduction of New Browsers
When new browsers enter the market, they bring their own rendering engines and interpretations of web standards. This can result in variations in how websites are displayed across different browsers.
Example: Apple’s Safari browser, with its WebKit rendering engine, may render certain CSS styles differently compared to Google Chrome with the Blink rendering engine. Websites that assume consistent rendering across browsers may experience issues.
3. Differences in Standards Compliance
Browsers interpret HTML, JavaScript, and CSS according to established standards set by the World Wide Web Consortium (W3C). However, not all browsers fully comply with these standards, leading to discrepancies in how websites are rendered.
Example: Internet Explorer, particularly older versions, had a reputation for not adhering to W3C guidelines. Websites developed specifically for Internet Explorer may encounter compatibility issues when accessed on modern standards-compliant browsers.
4. Evolving Web Technologies
As web technologies evolve, new features, APIs, and coding practices emerge. Browsers may implement these advancements at different rates, leading to compatibility gaps.
Example: Websites that utilize the latest JavaScript APIs may not function properly in older browsers that lack support for those APIs. Conversely, websites using outdated coding practices may not work correctly in modern browsers.
LambdaTest’s CSS background attachment can help assess browser compatibility by evaluating how the CSS property is rendered across different browsers. By testing your website on LambdaTest’s platform, you can identify and address compatibility issues caused by variations in browser rendering engines, ensuring a consistent experience for your users across different browsers.
How to Achieve Cross Browser Compatibility?
Achieving Cross Browser Compatibility requires developers to follow the best practices and use tools to test websites on various browsers and devices. Here are some ways to ensure Cross Browser Compatibility:
-
Set a Goal
Creating a web page that renders flawlessly across all browsers, versions, and devices is a challenging task. In fact, achieving such universal compatibility may require sacrificing certain desired features on your web page. Striving for compatibility with every browser’s initial version would result in a basic page with plain text. Therefore, the initial step in addressing browser compatibility issues is to identify and prioritize the browsers that are most important to your target audience.
2. Use Web Standards
Using web standards when developing a website can ensure Cross Browser Compatibility as it ensures that your site’s HTML, CSS, and JavaScript code works correctly on different platforms and devices.
But one common issue is the inconsistency in rendering CSS styles across browsers. For example, some browsers may interpret box-sizing differently, leading to variations in layout and spacing.
LambdaTest‘s CSS background attachment feature allows you to assess the compatibility of the CSS background attachment property across different browsers. The background attachment property determines whether a background image scrolls with the content or remains fixed as the user scrolls.
For example, you may find that the background attachment property behaves differently on Chrome, Firefox, and Safari. In some browsers, the background image may scroll with the content, while in others, it may remain fixed. These variations can impact the visual presentation and user experience of your website.
By using LambdaTest’s platform, you can compare and analyze the rendering of the CSS background attachment property across different browsers side by side. This helps you identify any compatibility issues and make necessary adjustments to ensure a consistent experience for your users.
3. Test Website on Different Browsers and Devices
Before launching a website, you must test it across different browsers and devices, such as desktop and mobile, to ensure that it appears the same on different platforms. This includes testing on popular browsers like Chrome, Firefox, and Safari, as well as different versions of these browsers. Additionally, testing on mobile devices and tablets is essential for mobile responsiveness.
Browser-specific bugs and rendering issues may arise when your website is accessed on different browsers and devices. For example, a JavaScript feature that works fine on Chrome may fail on Internet Explorer.

Emulators and virtual machines offer reliable solutions for mimicking various browsers and their configurations. Additionally, add-ons or browser extensions can further aid in testing websites across different browser and OS combinations.
5. Regularly Update the Website
Keeping your business website up to date with the latest web standards, browser developments, and security patches is essential for maintaining cross-browser compatibility. This includes regularly updating your HTML, CSS, JavaScript frameworks, and libraries to their latest versions.
Failing to update your website regularly can result in compatibility issues as browsers introduce new features and deprecate older ones. Outdated code may not work correctly or may have security vulnerabilities.
