The Role Of HTML5 in Web Development

By | November 19, 2015

It’s been about two years since the HTML fifth installment (i.e. HTML5) was rolled out. And, within such a short span of time, HTML5 has become the standard for developing websites and cross-platform mobile apps. No wonder that the latest HTML version has become a hit with developers, considering the fact that it makes the task of mobile application development a breeze.

Through this post, I’ll be covering some other reasons that has helped in making HTML5 the “lingua franca” for web developers.

1. Clean and Easy to Understand Code

Often when working in a web development team, you might need to take care of the work being performed by some other team member. But, messy HTML code can make it challenging for you to understand the code. In that case, making even little changes to your site will not be less than a nightmare.

But HTML5 help write clean and semantic code that help in separating the meaning of style from content. Take a look at the simple example of header code including navigation:

<div id="header">
<h1>Header Title</h1>
<div id="nav">
<li><a href="#">Nav1</a></li>
<li><a href="#">Nav2</a></li>

The above code snippet is clean, but you can make it even more clean and simple using HTML5, as you can see in the following code:

<h1>Header Title</h1>
<li><a href="#">Nav1</a></li>
<li><a href="#">Nav2</a></li>

Moreover, cleaner code also helps in obtaining higher search rankings.

2. Help Build Mobile-Optimized Solutions

Another big benefit of HTML5 is that it helps in creating mobile optimized websites as well as applications. With the rapid increase in the use of Smartphones and other mobile devices, it is imperative that your site can be easily accessed across different device displays; or else, you might lose a lot of your important customers.

HTML5 help create a responsive website that works well across all types of devices, delivering consistent online experience. And so, you don’t need to worry about introducing horizontal scrolling, as HTML5-enabled websites help mobile Internet users browse the sites more efficiently.

What’s more? HTML5 help in handling interactive tasks – that otherwise was done using Flash Player – on mobile devices.Microsoft Certification Exams: 70-480

3. It is Cross-Browser Compatible

HTML5 is cross-browser compatible, which means that an HTML5-enabled website or an app will be accessible across all of the major web browsers – be it IE, Chrome, Firefox, Opera, etc. But this doesn’t necessarily mean that all these browsers will support each and every HTML5 element, but will have the ability to read the HTML5 doctype.

4. Built-In Video/Audio Playback

In older HTML versions, in order to play a video and/or audio developers were required to use 3rd party programs, such as Adobe Flash Player and others. However, using such programs for having the web-based media playback functionality in a site resulted in errors. The introduction of HTML5 new <audio> and <video> elements has solved in solving this problem.

Below is an example that illustrates how you can embed a video playback code in an HTML5 document:

<video poster="music1.jpg" controls>
<source src=”music1.ogg" type="music1/ogg">
<source src="music1.mp4" type="music1/mp4">

Your browser does not support the <code>video</code> element.


As you can see in this code, two different video file formats are defined. In case, your visitor’s browser does not support the file with “.ogg” format, then it will move on to the “.mp4” instead.

5. Support Offline Caching

Often your web solution might not work when the Internet connection goes down. But, you can’t take such risk in today’s highly competitive world, or else you’ll lose your customers to your competitors. But, with the help of HTML5 webmasters can define the files that visitors’ browsers can save.

Essentially, HTML5 supports offline caching and this enable visitors to load webpage elements, even without the Internet connection. And so, you don’t have to worry about a blank page getting displayed in your site visitor’s even without network connectivity.


If you’re a web developer interested in using HTML5 for developing your site or an app, but are confused as to whether you should opt for HTML5 or not, then reading this post will definitely help you in making the right decision.

However, it’s up to you how you will be utilizing the latest HTML installment in addressing your needs. Especially, if you are just a novice and aren’t much familiar with HTML5, I’ll recommend you to grasp at least the basic knowledge of HTML5 first before jumping on the web development bandwagon.
