This markup serves to give significance to the text that it encloses.
Like other computer languages, HTML has many versions. Here we will talk about HTML5.
**NOTE :** You can test the different tags and elements as you progress through the tutorial on a site like [codepen](http://codepen.io/pen/) in order to see their effects, understand how they work and familiarise yourself with the language.
