Internet Explorer Online: Tackling Compatibility Issues in Enterprise Applications
Internet Explorer Online has long been a vital tool for businesses, especially when dealing with legacy applications and systems. Although newer browsers have taken the lead, many enterprise applications still depend on Internet Explorer due to compatibility requirements. This dependence often creates challenges for developers, who need to manage these compatibility issues while maintaining modern standards.
Understanding the features of Internet Explorer Online is essential for developers working with enterprise-level applications, as it can greatly impact the user experience and system performance. In this blog, we will explore the common compatibility issues faced with Internet Explorer Online and how developers can address them effectively.
Internet Explorer Online Compatibility Issues and Solutions
Below are the potential IE compatibility issues that can occur in enterprise applications and their solutions:
Handling Legacy JavaScript by Implementing Polyfills
Legacy JavaScript often breaks in modern browsers due to missing features. Polyfills can help by adding the necessary functionalities to ensure compatibility.
- Identifying Unsupported Features: Start by finding which JavaScript features aren’t supported in modern browsers. This allows you to determine where polyfills are needed.
- Implementing Polyfills: Use polyfills to bridge the gap between old JavaScript and modern browser capabilities. This ensures your scripts run as expected.
- Testing Compatibility: After adding polyfills, test the application in Internet Explorer Online to ensure everything works correctly. This verifies that all features are functioning.
- Monitoring Performance: Keep an eye on how polyfills impact load times. This helps you balance functionality with performance.
- Regular Updates: As new polyfills are released, update them to keep your application compatible with future browser versions. This helps avoid potential issues.
Using IE Compatibility Mode to Address Deprecated Features
Deprecated features often cause issues in modern browsers. IE Compatibility Mode allows you to mimic older versions of Internet Explorer, solving these problems.
- Enabling Compatibility Mode: Access the settings in Internet Explorer Online to enable Compatibility Mode. This helps in running applications that rely on older features.
- Testing Functionality: Test your application in Compatibility Mode to see if it resolves any deprecated feature issues. This helps identify whether further adjustments are needed.
- Combining with Document Modes: Use document modes in combination with Compatibility Mode for more granular control. This allows for fine-tuning specific parts of your application.
- Monitoring User Experience: Ensure that Compatibility Mode doesn’t negatively impact the user experience. This ensures that the solution works without introducing new issues.
- Documenting Changes: Keep a record of where and why Compatibility Mode is used. This helps in future troubleshooting and updates.
Eliminating CSS Inconsistencies by Standardizing Stylesheets
Inconsistent CSS across browsers leads to visual issues. Standardizing stylesheets ensures your application looks the same on all platforms.
- Centralizing CSS Files: Use a single, centralized stylesheet for all your pages.
- Using CSS Resets: Implement it at the beginning of your stylesheet to eliminate browser default styles. This creates a consistent baseline for all elements.
- Testing Across Browsers: Regularly test your application in Internet Explorer Online and other browsers. This helps identify and fix inconsistencies early.
- Adopting Modern CSS Practices: Use modern CSS techniques and frameworks that are designed to work across browsers. This increases compatibility and reduces the need for custom fixes.
Resolving Plugin Dependencies by Switching to HTML5 Solutions
Older web applications often rely on plugins like Flash or Silverlight. Replacing these with HTML5 solutions improves compatibility and performance.
- Identifying Plugin Dependencies: Audit your application to find where plugins are used. This gives you a clear idea of what needs to be replaced.
- Switching to HTML5: Replace plugin-based features with HTML5 equivalents. This ensures compatibility with modern browsers, including Internet Explorer Online.

Fixing Layout Breaks by Adjusting Box Model Settings
Differences in the box model can cause layout breaks between browsers. Adjusting box model settings ensures that your layout remains consistent across all platforms.
- Using Box-Sizing: Apply this rule to your elements. This ensures that padding and borders are included within the width and height.
- Testing Layouts: After adjusting the box model settings, test your layouts in Internet Explorer Online and other browsers. This helps identify and fix any remaining issues.
- Avoiding Inline Styles: Refrain from using inline styles that override your box model settings. This leads to more maintainable and consistent code.
- Standardizing Layouts: Use a CSS framework that normalizes the box model across browsers. This reduces the likelihood of layout breaks.
Using Compatibility View to Solve Inconsistent DOM Behavior
Inconsistent DOM behavior can cause functionality issues in modern browsers. Compatibility View in Internet Explorer Online helps resolve these inconsistencies.
- Enabling Compatibility View: Turn on Compatibility View in Internet Explorer Online to address DOM inconsistencies. This forces the browser to behave more like older versions.
