What are HTML and CSS used for? The basics of coding for the web
When it comes to building web pages, the coding language can, at first glance, appear incredibly complex. It may seem rather daunting having to take all this new information on board, but by breaking down each of the different elements involved, you’ll find that you can make sense of all these essential pieces of the puzzle.
If you’re thinking of building a website, then you’ll almost certainly have come across the acronyms HTML and CSS. These two essential tools form some of the foundations of any webpage. However, although they’re often used in conjunction with each other, they both serve very different purposes when it comes to web coding.
The key differences lie in their implementation, ease of use, their various features, and how they are structured, but at the end of the day, both HTML and CSS are the keys to unlocking how the World Wide Web works. Let’s dive into the details of both HTML and CSS, what they’re used for, and how to learn HTML and CSS.
What is HTML?
Let’s start by breaking down exactly what the acronym ‘HTML’ stands for. HTML stands for HyperText Markup Language. HyperText is effectively a text within a text, and a markup language is a language understood by computers, designed to essentially describe webpages and make the text you use more interactive.
It was originally invented back in 1989 as the publishing language of the web, and to put it very simply, it is the first building block in creating a webpage. When you first come across the world of HTML, you’ll likely encounter a whole ream of terms and phrases that are somewhat baffling too. The three main ones are elements, tags, and attributes.
HTML5 is the latest ‘version’ of HTML, and knowledge in this area is a growing trend in the job market. By and large, it has the same functionality as standard HTML but is much more dynamic and uses much less code to build something fantastic.
What is HTML used for?
In essence, HTML is used for creating the primary content of a webpage, giving it structure. You start by writing words, then apply tags or elements to these words. The web browser then reads this and can then understand the heading of a page, any paragraphs, and where the page starts and finishes, thus filling your web page with content.
HTML is supported by every single browser and is established on pretty much every webpage in existence. You don’t need any licenses, you don’t need to pay for it, and it can be pretty easy to learn and code. If we can compare a webpage to the human body, then HTML is the bones of the body.

What is CSS?
CSS is the acronym for Cascade Styling Sheets. In short, it is a sheet style language, which is a type of language you can use to describe the presentation of a markup language – in this case, to describe the movements of HTML. It effectively determines how the building blocks, as laid by HTML, are decorated and presented to the user.
CSS was first created around 1996 to make sense of HTML and make the webpage look and feel amazing. Just as with any language, you have to write CSS, and knowing how we write CSS is a skill that any webpage developer needs to have. Easy to maintain, CSS is the second part of the two-part tool kit for webpage creation.
Web accessibility is really important to many employers and companies nowadays, and there is fierce competition in creating the most accessible and well-designed webpage. Learning some software development fundamentals involving CSS can help you learn how to create accessible web pages.
What is CSS used for?
If HTML is the bones of the body, then CSS is the skin that covers it. It’s used for background colour, styling, layout, borders, shadowing – all the essential design bits and bobs that make a webpage look slick and smart. CSS enables you to distinguish between presentation and content by modifying the design and display of HTML elements.
Presentation and ease of use are a couple of the main things that CSS has bought to web design by translating the way content looks on a webpage and what else goes on it to complement that content. While frequently used in conjunction with HTML, it is actually independent of it, and can be used with any XML-based markup language.
The differences between HTML and CSS
Many people believe that HTML and CSS are the same, but they’re actually both quite distinct languages. While they are often used together in coding and Web design, they can both be used separately too, and both have a myriad of different applications. Let’s take a look at some of the key differences between HTML and CSS.
HTML defines the content and the structure of a webpage, whereas CSS translates the display and the design of the HTML elements
As a result, an HTML can incorporate CSS code in its files, but CSS cannot contain HTML in its sheets
HTML is one set ‘type’ or ‘method’, whereas, depending on requirement, CSS can either be internal or external
HTML isn’t used for presentation or visualisation, whereas CSS is
When it comes to writing the language, HTML has quite a clear and easy-to-understand syntax, whereas CSS can get a little bit more complicated and confusing
HTML uses ‘tags’ on either side of the content, whereas CSS uses ‘selectors’ that are followed by a declaration block
The code used by HTML is much larger than the one used by CSS, giving CSS a lesser webpage loading time
The primary function of HTML is to create web pages, whereas CSS is used to control the layout and the style of these webpages
Are HTML and CSS the same as other coding languages?
With so many different programming languages to choose from, you’ll find it tricky when it comes to choosing a programming language. However, an initial understanding of what the different programming languages are used for will be beneficial in deciding which one you choose to learn.
You’ll likely see many people decrying the fact that HTML and CSS are lumped in with other coding languages and tell you that they aren’t actually proper coding languages themselves. And while they might not be quite as flexible as other coding languages, especially in terms of their practical possibilities, they’re both highly specialised languages that can do really interesting things.
The main reason why HTML and CSS aren’t considered programming languages is because they only determine the structure and the style of the webpage you’re building. They don’t contain any instructions like the other front-end languages.

What other languages are useful?
Since humans started to create languages designed for coding and programming, it’s thought that there have been just under 9,000 invented. As with all languages, though, many of them have fallen by the wayside, or only have a very small handful of people who continue to use them.
While this number may seem daunting, it should be noted that you don’t need to know all of these programming languages. According to Wikipedia, there are only about 700 that are still in use today, which is still a fairly enormous number. But again, it’s not necessary to know them all. There are also new languages popping up every day too.
According to the website PYPL (Popularity of Programming Language Index), the top five most popular programming languages are as follows:
There are many other coding languages out there, but if you want to take your HTML and CSS prowess a step further, then learning one of these coding languages will provide you with a handy tool.
