What Is a Web Browser?
A web browser is an application that makes it possible to view the content on webpages. There are a variety web browsers available, but the majority of web designers focus their attention on ensuring that your website displays properly on the three leading web browsers: Mozilla Firefox , Google Chrome , and Internet Explorer. One of the biggest concerns today involves creating a responsive (not mobile) website. Responsive means that your website will automatically adjust to display properly on mobile devices such as smart phones and tablets. Mobile websites are the thing of the past where a duplicate website was created to specifically be viewed on mobile devices.
Web browsers translate HTML and CSS code into layouts, colors, and images.
