HTML Coding Basics – Digital Marketing Apprenticeship

HTML Coding

Learn how HTML works for the DM3 apprentice

In the Digital Marketing Level 3 Apprenticeship, HTML is arguably the hardest assessment you will face, spending roughly 2 weeks in workshops learning coding from scratch.

You’ll work together with your fellow apprentices to create your own websites for you to practice with. The teacher will guide you through creating HTML files to explain the different tags, attributes, elements and more! Suddenly all that confusing code that you’ve never been able to understand will all make sense.

Coding can lead to all these jobs:

  • Software Application Developer 
  • Web Developer 
  • Database Administrator 
  • Software Quality Assurance Engineer 
  • Network Administrator 
  • Computer Systems Engineer 
  • Computer Systems Analyst 
  • Business Intelligence Analyst 

Let’s get coding!

“Whether you want to uncover the secrets of the universe, or you just want to pursue a career in the 21st century, basic computer programming is an essential skill to learn.”

– Stephen Hawking – Theoretical Physicist

HTML – Headings

There are 6 HTML heading elements that start from 1, descending in size and importance. In HTML their syntax looks like this:

<h1>Heading 1</h1>
<h2>Heading 2</h2>
<h3>Heading 3</h3>
<h4>Heading 4</h4>
<h5>Heading 5</h5>
<h6>Heading 6</h6>

When rendered by the browser the tags look like this:

Heading HTML example

Rules of using Heading tags:

It’s very important to remember that each heading tag has a specific meaning when it comes to the structure of the HTML page. Search Engine Optimisation can be greatly affected by improper use of heading tags.

If you use <h3> to describe your main heading the browser won’t recognise that this is the most important heading. Remember to stay in order. <h1> then <h2> then <h3>, if you starting a paragraph after <h2> then you can use <h2> again if this is your desire. Only use one <h1> per page, this allows the browser to only need focus on one main heading. Avoid nesting headings too far into your code as the browser may miss them.

HTML – Paragraphs

These elements are used to display a block of text. In HTML its syntax looks like this:

<p>  This is a block of text! Lorem ipsum dolor sit amet, consectetur adipisicing elit.

The paragraph tag is used to help screen readers to find the text it needs to read. That’s why the alternative text on images is so important, so someone who is say blind can still understand what is happening on screen. Making the internet assessable for all.

HTML – Comments

Sometimes when dealing with HTML you’ll want to edit or remove code. Maybe because it’s not working correctly or you want, for example, a form to be hidden for the time being. Using comments to stop syntax from being read is the best way to do this. This is how you use it:

<!– Comments go between these tags. –>

HTML – Tags

Now you’ve seen some examples of HTML syntax it’s time to discuss the rules of tags, using <p> to explain. When writing syntax most tags have two parts a start tag and an end tag.


The end tag includes the / to show that the instructions are over. When wanting to nest tags within tags, for example, making the text bold there is a correct order that the tags need to be in.


If you don’t write them in order the browser simply won’t render them or you’ll have a confusing mess of symbols!

Sometimes you only want to make one work in your text bold:

<p>More<strong>important</strong>content</p>=More important content

This can get more and more complicated the more you add to the code so make sure to stagger the code in the HTML file so you can read it easier, kind of like how you’d order a list.

These are just a few things that you will touch upon during the Principles of Coding (for level 3 Digital Marketer Apprenticeship). But sure to use Codecademy to get a head start there are loads of free resources you can use.

Principles of Coding: Level 3


Course Description and Objectives

The course will give to the apprentices the opportunity to demonstrate knowledge and understanding of the principles of coding. There are mainly 4 areas the apprentices will get an understanding on:

  • Appreciation of logic
  • Software languages
  • Code compatibility on different platforms
  • Components involved to make the Web work

Here below you can find some additional information about the 4 areas covered in the Principle of Coding course:

  • Appreciation of Logic:
    • Useful to understand the basics of logic and logic gates such as and- or- not.
  • Programming languages:
    • Hypertext markup language (HTML), Javascript (JS), Java.
  • Interaction and compatibility of code on different platforms:
    • How to identify LAMP (Linux, Apache, MySQL, PHP) and XAMPP (Apache, MariaDB, PHP, Perl) Stacks
    • How to share different files formats across different platforms: PDF, HTML, Images (GIF, JPG, PNG), Video (Mpeg), Audio (Mp3)
    • How to create and protect feeds (using API keys).
  • Web components:
    • Define the terminology for Hypertext Transfer Protocol (HTTP), Hypertext Transfer Protocol Secure (HTTPS), Transport Layer Security and Secure Sockets layer (TLS/ SSL)
    • Discuss the scope of web and application server, hosting, database management system and content management systems.
    • Describe Search engines functions in regards to mark up languages, crawlers and search engine optimisation (SEO).
    • Define how cookies work and when are needed.
    • Roles of 2 key goernance groups: World Wide Web Consortium (W3C) and Internet Engineering Task Force (IETF).

Course Format, Duration and Examination

There are no specific pre-requisites to start the course. Therefore all the apprentices need to attend the full course in order to pass the exam and get the coding qualification. The estimated total qualification time is 50 hours.

The format for the exam is a one-hour multiple-choice examination consisting of 20 questions. No materials are allowed during the exam as it is a closed book one and the minimum required to pass the exam is 13/20 (65%).

My experience

I found it incredibly useful and I would recommend it to everyone. Before starting the course, I didn’t have any type of understanding of coding but I attended all the lessons, studied every day the material shared from the teacher and obtained my qualification.

I would recommend all the apprentices to follow carefully all the lessons, to do all the activities step by step and to ask as many questions as possible to the teacher. I found the teacher well prepared, keen on helping all the attendees and open to all the questions.

If you are interested in starting a career in Digital Marketing, broadening your knowledge in the principles of coding and obtaining a coding qualification this course is a fundamental pillar. The Level 3 Award in Principles of Coding will give you the opportunity to pursue a career as a web developer, database administrator, computer programmer and computer system analyst just to name some.
