HTML5 and CSS3 – What you Need to Know

What is HTML?

HyperText Markup Language is a type of coding that’s hidden beneath every page on the internet, and is used to structure and present web pages. It’s made up of various tags, elements and attributes, each with its own unique function. Currently, HTML supports text and image-based media, but any video or audio you see on a website is powered by an external force; third-party software and plug-ins have to be installed for these types of media to work.

How is HTML5 Different?

The much anticipated HTML5 will essentially bring the internet into alignment with the modern digital world. With the internet becoming the go-to place for video and audio, and smartphones, tablets and other low-powered mobile devices becoming common place, it makes sense for the web to cater to these platforms more effectively.

Video and Audio

The biggest change to be seen in HTML5 is that it will have native support for video and audio – no more annoying software updates before you can watch that video you just stumbled on. Websites created using HTML5 will just do it. Ditto for audio. So long as your browser supports HTML5, that is – all browsers will need to make updates to their systems in order to be able to handle the latest and greatest HTML5 has to offer.


Another wonderful benefit of HTML5 is that it will have the ability to cache information from your email, online calender, etc. meaning you’ll access to it even if your internet connection drops out. With the internet becoming a core part of the business and working world, it makes little sense that there’s no easy way to check what was in your inbox the last time you were online – and HTML5 will remedy this situation.

Faster loading

For web developers, HTML5 will offer an exciting world of more streamlined coding, with various elements becoming obsolete while newer, more effective ones are ushered in. It should also require less power than its predecessor, in keeping with the uprising of the latest mobile technology – that means faster loading times for smartphones and tablets.


Cascading Style Sheets are used to customise design elements such as fonts and colours, among countless others. CSS can be coded straight into HTML files, but it’s far more efficient to create a separate CSS file which can be then be used by numerous web pages, negating the need to paste the same code into different pages of HTML.

What’s new with CSS3?

The main change to CSS3 is to allow increased control over various design elements; it’ll be possible to tweak things that were previously untweakable, such as shadowing and fading, and the ability to round the corners on boxes. Basic elements originally used in HTML, such as font and centre will be dropped from use and replaced by more powerful coding in CSS3 too. It might not sound like much, but designers will be able to create much more sophisticated web pages with less coding.

It’ll take some getting used to, and there will undoubtedly be hiccups along the way, but the advent of HTML5 and CSS3 should spell a more efficient web, in keeping with the fast-paced online world we’re quickly advancing towards. We expect to see it come into action towards the end of 2014, but it may not be fully up and running and integrated across all browsers for several years after that. Good things take time, you know.
