Code Evolution


What is HTML used for?

HTML stands for HyperText Markup Language. It refers to the accepted system of tagging text files on webpages to create colour, graphics, hyperlinks and fonts.

HTML is the code that is used to structure a web page and its content. For example, content could be structured within a set of paragraphs, a list of bulleted points or using images and data tables.

In October of 2014, a massive update to this standardized system launched HTML5. What is HTML5?

HTML acts as the Internet’s primary language. It defines the connections from your document to the parts that make the document interactive. Tags shape the text structure using elements indicated by the “<” and “>” characters.

<!DOCTYPE html>

<h4>My First Heading</h4>

<p>My first paragraph.</p>


My First Heading

My first paragraph.

Further development languages emerged to define other parts of a document since the first introduction of HTML. In the old HTML, these other languages required further software, like browser plugins, to work.

What is HTML5

The HTML5 structure integrates all these other coding languages used to build modern websites. The HTML code still provides the basic structure, but now it also includes Cascading Style Sheets (CSS) and JavaScript.

NOTE: The CSS controls the physical presentation of the document while JavaScript makes things happen on it.

HTML5 combines all the major internet design languages to make development easier. Now, developers can even integrate audio and video with the updated version.

Differences Between HTML5 vs HTML

The audio and video capabilities are a huge difference between HTML and HTML5. Canvas, SVG and other popular virtual vector graphics can also be used with HTML5. In the past, you would need to add VML, Silverlight or Flash to use the vector graphics.

In the old HTML, only browser caches could use web SQL databases. HTML5 allows all pages to temporarily store data in an application cache through an online SQL database and it also allows JavaScript to run in the background of the web browser.


The new HTML5 structure has better parsing rules that offer enhanced compatibility. It also gets rid of some deprecated elements like noframes, acronym, font, big, strike, center and frame.

HTML5 supports inline SVG and MathML not available in previous HTML versions. It also introduces new form control types like email, date and time, range, number, URL, search and much more…

Finally, HTML5 adds in many new elements that modern developers will find very useful, such as summary, command, audio, embed, canvas, mark, nav, source, video, track, date, time, aside

Advantages for Developers

The makers of HTML5 wanted developers to enjoy greater flexibility in their design while improving the end user experience. The main advantages that the new HTML5 features give developers include:

  • Improved Support for Web App Features. HTML5 developers wanted to transform how browsers work by allowing them to act as application platforms. Websites will only continue to increase in complexity and this feature allows developers to have better control over website performance. HTML5 integrates important elements like Flash and JavaScript to make it easier.
  • Standardized Error Handling. Nowadays, most web browsers come with special support elements to understand incorrect HTML code. Before launching HTML5, developers had no standardised procedure to deal with this. All websites contain incorrect code and handling the error in a quick and efficient manner makes all the difference.
  • Enhanced Element Semantics. HTML5 seeks to make code more intuitive as well. Developers made improvements to the semantic roles of the many elements already found in HTML4. Div elements no longer matter since header, nav, article and section replace all these old elements.
  • Addition of Canvas. The most anticipated of the new HTML5 features, the canvas element greatly impacted Adobe Flash. HTML5 rendered Adobe Flash obsolete since so many people seem to prefer its structure. Please, remember that canvas acts only as the graphics container, you still must execute a script to define the graphics.
  • Personalized Data Attributes. Although HTML4 did allow developers to add custom attributes, it came with many risks. Sometimes the personalized data attribute would completely stop a page from rendering and it caused many invalid and incorrect documents. In HTML5, the “data-*” attribute eliminates these issues.
  • Better Mobile Functionality. Even professional web developers encounter hardships when creating a website’s mobile version. HTML5 makes it much easier to cater to these lower-powered devices like smartphones and tablets. Mobile websites and browsers crash much less frequently now.

Since HTML5 basically eliminates Adobe Flash, the end users enjoy an improved and richer graphic experience. They can also access any audio or video files right on the website without needing to download extra plugins. Great, isn’t it?
