Please somebody inform me What care should be taken by web developer to handle browsers compatibility issues.
With the wide array of browsers present, chances are that the website will face varied issues over these. Adding to the trouble is the advent of numerous devices which together, create an extremely large number of combinations to test on.
The website might sport the best design and features but as long as it is not tested to work on every possible platform, it will remain a ‘Work in Progress’. So to overcome the challenge of testing and simplifying the process, there are several cross-browser testing tools like LambdaTest.
Yet, sometimes some minimal steps can prevent cross-browser compatibility issues. Today we’ll look at some of the most common cross-browser compatibility issues and how to fix them.
1. DOCTYPE Error
When there is a missing “Doctype” tag in the webpage, the browser tends to go into the quirks mode. At the same time, if there is a browser which doesn’t support HTML5, it will not understand which version to look for. This would lead to some of the tags to become unresponsive and the webpage will not look as intended.
The solution to this problem is a simple one line code at the very beginning of the code. It looks like this:
This will ensure a perfectly rendered site in every browser available.
2. Browser Detection
This is a common cross-browser compatibility issue which is faced due to obsolete java scripts. But, tackling this cross-browser issue is easy. You can remove the browser detection. Instead use Modernizer, a collection of ‘superfast tests’ which list all the features of a browser, hence giving you a seamless experience. Using this the developer can direct the site to focus on features rather than browsers.
3. Vendor Specific functions
The functions defined by the developer are, at times, contain functionality specific to browsers. While writing the CSS code, these browsers are denoted by specific codes.
To ensure proper functionality and avoid this cross-browser issue, one needs to ensure the addition of the function without the prefix as well. This will ensure there is no error in other browsers.
Common vendor prefixes include:
- Mozilla Firefox (-moz)
- Internet Explorer (-ms)
- Opera (-o)
- Safari and Chrome (-webkit)
4. Use cross-browser friendly libraries and frameworks
Most websites are comprised of various third-party libraries and frameworks. These tools help developers to bring in structure, scalability, and security to the web applications. Using the wrong alternatives to these libraries can lead to a variety of cross-browser issues that can range from the incorrect working of library features to the complete framework crash.
To avoid such issues, it is highly recommended to use well known and trusted frameworks that are cross-browser friendly.
Angular JS and React JS are some examples of cross-browser friendly web application development frameworks.
Bootstrap, Animate are examples of trusted CSS libraries.
JQuery is an example of a cross-browser friendly scripting library.
