HTML and CSS coding are two different things, but they often work in conjunction with one another to create an informative, aesthetically-pleasing website or online document. In this article, we’ll take you through what HTML is, what CSS is and the differences between the two. We’ll also take you through the advantages and disadvantages of using each one. So without further ado, let’s talk about what the difference is between HTML and CSS coding.


What is HTML?

HTML, or hypertext markup language, as it’s also referred to, is code that’s used to create websites and certain website applications. Hypertext is similar to a hyperlink in the sense that it’s text wrapped within a text. Markup language simply helps with the formatting side of things, such as the layout of the text. Makeup language is the part of HTML that can create tables, for example, thus ordering the text on the page. Essentially, it helps to make the text, and the content itself, more dynamic and interactive in the process.


The pros & cons of HTML

There are many different benefits and downsides to using HTML for creating and laying out the text. Where some people prefer to use this as an easier way of formatting text within a programme, others would prefer to simply write the text as it would appear on the page. That’s because, like with most things, there are advantages and disadvantages to using HTML.

Pros of HTML
  • HTML is straightforward to write
  • Every internet browser supports HTML
  • It’s quick to download as the text is compressible
  • It’s easy to learn
  • It’s simple to use


Cons of HTML
  • It can only create plain and static pages
  • Security features are poor with HTML
  • It’s not very flexible in comparison to developers like Dreamweaver
  • Styling capabilities are limited, which is why it’s preferred to use CSS in combination with HTML


What is CSS?

CSS, also known as cascading style sheets, is a language, or code, used to style a website page or document. It affects things like font colour, the background, foreground and other design aspects online. It’s designed to simplify the design process, making things quicker and easier for those who are looking to create a website in a reasonable amount of time. Style definitions are saved in external .css files.


The pros & cons of CSS

CSS, arguably, is easier and more straightforward to use than HTML, but even so, it too comes with advantages and disadvantages that only become apparent when someone decides to write CSS code. However, because CSS is used for the design and styling side of a website page or document, it’s an incredibly important aspect of website design and development. So what are the pros and cons of CSS?

Pros of CSS
  • You’ll be able to use it to style many different documents and pages, sometimes simultaneously
  • You won’t require additional network requests in order to retrieve style information 
  • It’s easy to go back in and change things as and when needed
  • CSS saves a lot of time in the long run


Cons of CSS
  • It’s vulnerable
  • It has many different levels to it, which can be confusing for some users
  • The page might become slower to load
  • It’s not uniformly supported by all browsers


The key factors where HTML & CSS differs the most

We’ve divulged what each one does and when it’s used. We’ve also discussed the advantages and disadvantages of each, but where does HTML and CSS differ the most? Below are the key factors where HTML and CSS are different from one another:



HTML is a markup language used to organise and define website page text using syntax and formatting that isn’t used, or available, in CSS sheets or coding. However, because CSS is completely independent of HTML coding, it’s compatible with many different markup languages that are XML-based.


CSS is specific only to the design and presentation of a website page or another online document, such as an article or infographic. HTML, on the other hand, defines the website page structure. Even then, they’re both easy and straightforward to write and, in the process, they’re simple to implement.


CSS only uses selectors to declare block statement syntax, whereas HTML relies solely on tags for the purpose of structuring content as well as other elements on a website page, aside from the specific style of the website page or another online document. This is yet another factor where HTML and CSS differ.


HTML is used, primarily, to add the core content of a website page. It enables people to view the text on a page, but it can also be used to define similar aspects that CSS coding will also define. When used in combination with each other, you’ll be able to dictate the following things:

  • Colour
  • Font colour
  • Font size
  • Background colour
  • Font type
  • Foreground colour
  • Layout
  • Design of the website page
  • Page style formats
  • Similar functions and other features


CSS isn’t supported by every browser on the internet, but HTML is. This is where using them together could prove to be problematic for some website developers and designers. However, there are things that can be done which allows website pages to be viewed in different browsers, despite the CSS or HTML coding used or the browser it’s viewed in.
