Perhaps the biggest issue is the poor browser support XHTML currently enjoys. Internet Explorer and a number of other user agents cannot parse XHTML as XML. Thus, it is not the extensible language it was promised to be.

14⟩ Explain what is the difference between linking to an image, a website, and an email address?

To link an image, use <img> tags. You need specify the image in quotes using the source attribute, src in the opening tag. For hyperlinking, the anchor tag, <a>, is used and the link is specified in the href attribute. Text to be hyperlinked should be placed between the anchor tags.

Little known fact: href stands for "hypertext reference." When linking to an email, the href specification will be "mailto:send@here.com." See examples below:

<a href="http://www.rendc.org/">global guideline</a>

<a href="hussain@rendc.org">Email Me</a>

15⟩ Explain what is the coolest thing you ever coded? Do you have any personal projects you are working on?

These two questions are interchangeable. Any developer worth his weight had to practice somewhere or on something before they landed their first gig. If not, how did you get this interview anyway?! Review your past experiences, and even if they were boring to you, figure out a new frame of reference that demonstrates passion and a zest for learning.

16⟩ Explain what's the real difference between HTML and HTML5?

There are many. From a broader perspective, HTML was a simple language for laying out text and images on a webpage, whereas HTML5 can be viewed as an application development platform that does what HTML does that and more, including better support for audio, video, and interactive graphics. It has a number of new elements, supports offline data storage for applications, and has more robust exchange protocols. Thus, proprietary plug-in technologies like Adobe Flash, Microsoft Silverlight, Apache Pivot, and Sun JavaFX are no longer needed, because browsers can now process these elements without additional requirements.

17⟩ Tell me what is the difference between <div> and <frame>?

A <div> is a generic container element for grouping and styling, whereas a <frame> creates divisions within a web page and should be used within the <frameset> tag. The use of <frame> and <frameset> are no longer popular and are now being replaced with the more flexible <iframe>, which has become popular for embedding foreign elements (ie. Youtube videos) into a page.

19⟩ Explain what is "Semantic HTML?"?

Semantic HTML is a coding style where the tags embody what the text is meant to convey. In Semantic HTML, tags like <b></b> for bold, and <i></i> for italic should not be used, reason being they just represent formatting, and provide no indication of meaning or structure. The semantically correct thing to do is use <strong></strong> and <em></em>. These tags will have the same bold and italic effects, while demonstrating meaning and structure (emphasis in this case).
