Major Browser Compatibility Issues You Need To Be Aware Of

Surfing the web has become very easy with the availability of many internet browsers today. People can have their choice of pick from options like Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and many more, to access the webs seamlessly. However, not all websites may load properly on all web browsers. This is mainly because not all websites are cross-browser compatible.

Cross-browser compatibility is one of the crucial things you need to test your website for, if you want to provide an excellent user experience across browsers and devices. Here are a few compatibility issues that are common with browsers like IE, Firefox and Chrome:

Incorrect DOCTYPE

DOCTYPE is a tag that you generally use in the first line of your HTML. It tells your browser which version of HTML you have used to write your page. It is something that allows the browser to display the content correctly. By including the correct DOCTYPE you can prevent a lot of browser compatibility issues from occurring.

Absence of CSS Reset

Every web browser has its own set of basic as well as internal CSS styles that it applies to the content of your website. This is why each browser renders the pages in a different way. If you want all the browsers to render your content in a similar way, you will have to use what is known as “CSS reset stylesheet” on your web page. This will stop the browser from adopting its own CSS style so that your website is displayed as it should be.

Cross-browser compatibility


Most websites interpret CSS and HTML codes very differently. This is mostly due to a missing <div> in your code. A few browsers like Firefox and Chrome manage to add this <div> code naturally in order to render the site properly. But there are many other browsers that don’t. As a result the rendering of your page would seem different in different browsers.

Older Browser Detection Scripts

Browsers that run older versions of JavaScript might find it difficult to load pages with modern elements. In order to prevent such issues it is important that you find out if the browser detection feature is outdated. If it is, it would be better to eliminate the detection feature, for better rendering of your content.

Vendor Specific CSS Styles

You would often find it difficult to identify the CSS functionality of browsers. This is the case with most of the newer browsers. They generally adopt vendor-specific CSS styles that often come without the specifications about the versions. Therefore, if you want your code to work perfectly across all browsers, you would be better off including an unprefixed version alongside the prefixed version.
