Combining HTML, CSS, and Python equips you to build dynamic, interactive websites. HTML provides the structure, CSS adds styling, and Python can be used to interact with and manipulate the HTML content. By understanding how these technologies work together, you can create visually appealing and functionally robust websites.

This tutorial guides you through the basics of creating HTML files, using CSS for styling, and leveraging Python to manage HTML content programmatically.

By the end of this tutorial, you’ll understand that:

  • Python can be used alongside HTML and CSS to create dynamic web content.
  • HTML, CSS, and Python are sufficient for developing basic web applications.
  • Learning HTML, CSS, and Python simultaneously is feasible and beneficial.
  • Learning HTML and CSS first can give you a solid foundation before tackling Python.
  • You can mix Python with HTML to automate and enhance web development.

Explore how HTML and CSS can enhance your Python projects, enabling you to create impressive websites and understand web frameworks like Flask and Django more deeply.

You’ll get an introduction to HTML and CSS that you can follow along with. Throughout this tutorial, you’ll build a website with three pages and CSS styling:

While creating the web project, you’ll craft a boilerplate HTML document that you can use in your upcoming web projects. You may find that the source code will come in handy when you’re working on future projects. You can download it here:

After learning the basics of HTML and CSS, you’ll find ideas on how to continue your journey at the end of the tutorial.

Create Your First HTML File

Think of any website that you’ve recently visited. Maybe you read some news, chatted with friends, or watched a video. No matter what kind of website it was, you can bet that its source code has a basic <html> tag at the beginning.

HTML stands for HyperText Markup Language. HTML was created by Tim Berners-Lee, whose name might also ring a bell for you as the inventor of the World Wide Web.

The hypertext part of HTML refers to building connections between different HTML pages. With hyperlinks, you can jump between pages and surf the Web.

You use markup to structure content in a document. In contrast to formatting, the markup defines the meaning of content and not how it looks. In this section, you’ll learn about HTML elements and their roles.

Writing semantic HTML code will make your documents accessible for a wide range of visitors. After all, you want to enable everybody to consume your content, whether they’re visiting your page with a browser or using screen reading tools.

For each HTML element, there’s a standard that defines its intended use. Today, the standards of HTML are defined by the Web Hypertext Application Technology Working Group (WHATWG). The WHATWG plays a similar role for HTML as the Python Steering Council does for Python.

Approximately 95 percent of websites use HTML, so you’ll be hard-pressed to avoid it if you want to do any web development work in Python.

In this section, you’ll start by creating your first HTML file. You’ll learn how to structure your HTML code to make it readable for your browser and for humans.

The HTML Document

In this section, you’ll create a basic HTML file. The HTML file will contain the base structure that most websites are built with.

To start things off, create a file named index.html with some text:

HTML index.html 
Am I HTML already?

Traditionally, the first file of your website is called index.html. You can think of the index.html page as akin to the main.py or app.py file in a Python project.
