The Difference Between CSS & HTML

Your Guide To Determining The Difference Between CSS & HTML

Working in the web design and development business, there are a lot of questions regarding the language we use when building out our websites. Though for many customers, they leave the development terms to the experts, it’s still important to have a brief understanding of the language used on your site. 

What is HTML?

HTML, or Hypertext Markup Language, is the standard language used to create web pages and other types of online content. It is a markup language, which means it uses tags to identify different types of content within a document.

HTML uses tags to define the different types of content within a document. For example, the <h1> tag is used to define a main heading, while the <p> tag is used to define a paragraph. There are many other tags available in HTML, each with its own purpose and meaning.

In addition to tags, HTML also uses attributes to provide additional information about an element. For example, the <img> tag is used to insert an image into a web page, and the “src” attribute is used to specify the URL of the image file. For example, say you want to create a simple page with a heading, paragraph, and image within it:


<!DOCTYPE html>



<title>My Web Page</title>



<h1>Welcome to my web page!</h1>

<p>This is a paragraph of text that will appear on my web page.</p>

<img src=”my-image.jpg” alt=”A beautiful landscape”>




HTML is a foundational language for web development, and is used in conjunction with other technologies such as CSS and JavaScript to create dynamic and interactive web pages. By learning HTML, you can create your own web pages and share your content with a global audience. It’s a great starting point if you’re interested in web design or development.

What is CSS?

CSS, or Cascading Style Sheets, is a language used to style and format web pages. It is an essential tool for web designers and developers, as it allows them to control the appearance and layout of web pages, making them more visually appealing and user-friendly.

To understand how CSS works, it’s important to understand the basic structure of an HTML document. HTML defines the structure and content of a web page, while CSS defines the presentation and style.

In CSS, you select HTML elements and apply styles to them using selectors and declarations. Selectors identify the HTML elements you want to style, and declarations specify the style rules you want to apply. For example, to select all the heading elements (h1, h2, h3, etc.) and set their color to red, you would use the following code:


h1, h2, h3 {

  color: red;



CSS also allows you to create classes and IDs, which can be used to style specific elements on a web page. Classes are reusable styles that can be applied to multiple elements, while IDs are unique styles that can only be applied to a single element.

One of the key benefits of CSS is that it enables you to create responsive designs that adapt to different screen sizes and devices. This is achieved through the use of media queries, which allow you to apply different styles based on the size of the viewport.

While CSS can be a complex language, it’s important to start with the basics and build your skills gradually. By mastering the core concepts of selectors, declarations, classes, and IDs, you can create beautiful and functional web designs that engage and delight visitors.

HTML vs. CSS – The Difference

One of the key differences between HTML and CSS is their focus. HTML focuses on the content and structure of the webpage, while CSS focuses on its presentation and style. This means that HTML defines what the webpage is, while CSS defines how it looks.

Another difference is their syntax. HTML uses tags enclosed in angle brackets, such as `<h1>` for headings and `<p>` for paragraphs. CSS, on the other hand, uses selectors and declarations, such as `h1 { color: red; }` to select the heading element and set its color to red.

In terms of functionality, HTML is essential for creating a webpage, while CSS is not strictly necessary. You can create a basic webpage with just HTML, but it will lack the visual appeal and user-friendliness that CSS provides. CSS is what allows you to create engaging and dynamic web designs that keep visitors engaged and coming back for more.
