HTML 5 tutorials Part 4 - Introduction to HTML5

Initial 3 parts Part1, Part 2 and Part 3 we talked about the basics of HTML. I know most of the developers usually know about this stuff but it is always to brush up the basics before talking about the new stuff.

From this part we will start more on HTML5. First question that come to mind is what are the problems that are being solved by HTML5?

What is HTML5?

HTML5 is combination of new html elements and lots of new JavaScript APIs. I know this not a definition you were expecting but in reality this is it. So do we really need to call it HTML5? I think we can just say HTML as there will be new development but I guess there won't be any HTML6. It will be called on HTML.

Problems solved by HTML5

SEO

Previous we use one tag mostly in the web page design, I guess you know it is div. So for search engine to identify different parts of the page is by scanning the ids. So we need to keep consistent ids across the web pages. How this is solved by HTML5?

HTML5 provide us different html tags like header, main, footer which are used to specify the header content, main content and footer content of the page. Which makes is easy for the search engines to find specific contents of the page. It provides semantics for the web pages.

Mobile Friendly

Billions of people are now using mobile device and we want to make sure that our web pages are more suitable for mobile. If you open up a web page on mobile than you get an option to make the web page mobile friendly and read in mobile mode. As soon as you click on this option the web page completely change the design as per the mobile form factor. So it is easy to develop the web page for vast variety of mobile form factors.

Multi Media

HTML5 provide tags which can be used to host the multi media content like music, video, graphs and games. Now developer can develop a full fledged  game only in HTML5 and supporting CSS3 and javascript. So we do not need to use Flash or Silverlight to show videos or animated stuff on web pages. 

we will discuss these features in details as we move along the tutorials. I am sure there are other many important things which can be done easily in HTML5. Please add these to comments to share with others.

So here is the basic structure of HTML5 page that you can see.

Swift – All you need to know – Part 1

As we are studying the Swift programming language for past couple of months. While studying the language I cam across many features of the programming. So I thought to compile all those features with some brief introduction so that if some one just want to have a sneak peak at the features he/she can just go though this blog.

So this is the part -1 of the series I am thinking to write. Hope to complete it soon and cover the features in its entirety.

Objective C has been the core programming language for Apple software Development. It has been there for 20 years and serving us well. As per Apple they have worked for 4 years to design Swift Programming Language.

So what is it that they wanted to achieve with Swift? As per Apple during the Swift Programming language intro in WWDC 2014 they want “Objective C without the baggage of C”.

Swift is Fast, Safe, Modern and Interactive programming language. Here are the few key points of Swift programming language:

•       Adapts safe programming patterns by using the Type Inference and Generics.

•       It adopts the readability of Objective-C’s named parameters and the power of Objective-C’s dynamic Object Model.

•       Provides seamless access to the existing Cocoa Framework and Objective-c code.

•        Develop apps for iOS and Mac OS both.

You might have heard about the playgrounds the new feature in XCode 6 where you can use Swift language and see the output of the programming as you finish typing the code. We can discuss Playground and its features in other blog. Today we will talk about what all features Swift Programming language has come up with and will have brief introduction about each feature for you to kick start the language.
