Dear readers, these HTML5 and CSS3 Interview Questions have been designed specially to get you acquainted with the nature of questions you may encounter during your interview for the subject of HTML5 and CSS3.  Normally questions start with some basic concept of the subject and later they continue based on further discussion and what you answer.

When it comes to interviews for web developers, HTML plays a significant role and it is very easy to learn and use.

HTML5

HTML or Hyper Text Mark-up Language is the language used for presenting websites and web content. HTML5 is the latest version, made official by the World Wide Web Consortium in 2014. Having a good grasp of HTML means you’ll be able to create, present and edit a whole variety of content on the web.

 

CSS3

CSS (Cascading Style Sheets) essentially ‘enhances’ HTML, giving developers and users more control over how pages and content is displayed. It is responsible for creating more visually engaging web pages, applications and interfaces. CSS3 is the latest version, and has many more extended features than previous versions – although it is backwards compatible.

The  HTML5 and CSS3 Certification ensures you know planning, production and measurement techniques needed to stand out from the competition. 

There is no difference. Just like HTML and HTML5. CSS3 is simply the newer “version” of CSS which has more advanced features than earlier “releases. Likewise, HTML5 simply is HTML and CSS3 is simply CSS. Both HTML5 and CSS3 became marketing buzzwords way above and beyond the technologies that they are referring to.

By using HTML5 and CSS3, many businesses are developing and expanding web content and web apps with an aim to create well-defined and accurate web pages and web systems that can be accessed on different devices, web browsers, and operating systems.

The main difference between CSS and CSS3 is that CSS3 has modules. CSS is the basic version, and it does not support responsive design. CSS3, on the other hand, is the latest version and supports responsive design.

You can learn HTML without having to go to a college or a boot camp. In fact, you can learn HTML at the comfort of your own home. However, you will need learning materials to enable you to learn effectively. Fortunately, there are a lot of websites and online courses that can help you learn.
