The availability of different internet browsers has made it a lot easier for users to surf and engage on the web these days. Popular browsers like Google Chrome, Mozilla Firefox, and Internet Explorer offer a different set of features that allow the users to seamlessly access the web. The presence of so many browsers raises an issue with compatibility. It prevents certain websites from loading properly on certain web browsers.
A few compatibility issues are common to most of the web browsers, and resolving them will help to create a more open web. Cross-browser compatibility issues require the development of websites that are compatible with almost all the available browsers. Some of the browser compatibility issues that are common across most of the browsers like Chrome, Firefox, and IE, are discussed below.
The DOCTYPE is something included in the first line of the HTML. Having the DOCTYPE tag in front of the HTML is of vital importance as it can help to create a smoothly rendered website. Browsers such as the Internet Explorer interprets many of such key web standards differently that results in various browser errors. This can hinder the pages to load properly in the browser. Checking the DOCTYPE is an effective way to prevent similar browser compatibility issues from occurring again.
Absence of CSS Reset
Almost every web browser contains a set of internal and basic CSS styles that are applied if the website fails to override them. The way the pages are rendered is different for each browser and can prevent the web page from displaying properly. Using a CSS reset stylesheet on a web page is one way to ensure that all the browsers render the content using the same criteria.
No Valid HTML/CSS
HTML and CSS are interpreted differently by most browsers and can occur due to a missing <div> in the code. Browsers such as Chrome and Firefox naturally add the <div> code if it is found missing and thereby render the site properly. However, this isn’t the case with other browsers and can result in the difference in the rendering of the page.
Older Browser Detection Scripts
Vendor Specific CSS Styles
Most of the new browsers often hide their latest CSS functionality behind vendor-specific CSS style. The vendor may eliminate the vendor-specific version or include an altered version after the style is determined. So it is best to ensure that the code works perfectly in all the browsers by including an unprefixed version beside the prefixed versions.
