Web browser compatibility measures are undertaken by Web developers who are committed to producing Web products that provide predictability and consistency across the preferred Web browsers of targeted end users.

Cross-browser compatibility means a Website is attuned and reliable in looks, layout, color, functionality, interactivity, and proportion across all existing Web browsers, regardless of the browsers' insignificance or popularity differences from version to version. Multi-browser compatibility is constant and functionally rendered across the most commonly used browsers in a client's target market. HTML5 uses different standards and is supported by various browsers. These browsers provide different versions of support.

Rendering engines are a set of tools that are used in most browsers that support different HTML features. Some of the rendering engines of other browsers are as follows:

• Gecko - The Gecko engine is the main engine of Mozilla Firefox and several related browsers. It has support for various HTML5 features. Although Firefox is an eminent and highly appreciated browser in the Web development community, it does not yet have full support for HTML5.
  
  
• Trident - The Trident engine is used by different versions of Internet Explorer (IE). Currently, HTML5 is not majorly supported by the Trident engine. IE9 was anticipated to support HTML5 completely, but it has failed to support some features such as advanced form element support and geolocation.
  
  
• WebKit - The WebKit engine is supported mainly by the Safari browser used in Apple Macs iPhones, iPads, and other Apple products. This engine is based on the open-source KHTML project. Webkit is also the base for Android-based browsers such as Google Chrome.
  
  Webkit has evolved to become the standard rendering engine for mobile platforms. WebKit has maximum support for most of the HTML5 elements, although it still does not support everything.
  
  
• Presto - Presto is the engine used in Opera browsers. Opera browsers are considered to be technically superior browsers, but the market share of Opera browsers is still low.
  
  

Each browser interprets the Website code differently, which means that it can appear differently to users using different browsers.

Best practices for optimum browser compatibility are as follows:

• Test the Website in different browsers - Once the Website design is created, review the Website's appearance and functionality in multiple browsers to ensure that all users are getting the same experience according to the design. Preferably test different versions of the same browser also as they can show the Website differently.
  
  
• Write good and clean HTML coding - Sometimes the Website may appear correctly in some browsers even if the HTML code is not valid, but there is no guarantee that it will appear correctly in all browsers. To ensure that the page looks the same in all browsers, it is best to write Web pages using valid HTML and CSS codes, and then test them in many browsers. Using external CSS can help pages render and load faster.
