HTML, CSS, JavaScript: The Basics for Business Owners

In this blog post, we’re going to change things up and get more technical. We’re going to discuss the three main web design languages: HTML, CSS, and JavaScript. By the end of this post, you should have a better understanding of each language as well as how they work together to create web pages.

HTML is the structure of a webpage. It is the foundation that everything else is built on top of. CSS is what makes a webpage look pretty. It is responsible for the layout, colors, and fonts. JavaScript is what makes a webpage interactive. It can be used to create things like menus, forms, and animations.

Think of HTML as the skeleton of a webpage, CSS as the skin, and JavaScript as the muscles. They all work together to create a functioning web page.

Now that we know a little bit more about each language, let’s talk more about the specifics.


  • The HTML code of a web page is read by the web browser and then rendered into a web page.
  • HTML tags are used to structure the content of a web page.
  • Common HTML tags include: `head`, `title`, `body`, `p`, and `a`.


  • CSS code is used to style the HTML code of a web page.
  • CSS can be used to change the color, font, size, and position of HTML elements.
  • CSS selectors are used to target HTML elements that you want to style.
  • Common CSS selectors include: `class`, `id`, and `element`.


  • JavaScript code is used to create interactive web pages.
  • JavaScript can be used to validate form data, create cookies, and detect user’s browser information.
  • JavaScript functions are used to run a piece of code when an event is triggered.
  • Common events include: `click`, `load`, and `mouseover`.

What is AJAX?

You’ve probably heard of AJAX before, but what is it? AJAX stands for Asynchronous JavaScript and XML. It is a web development technique used to create interactive web pages. AJAX allows for the web page to communicate with the server without refreshing the page. This makes web pages more responsive and fast.

Why does this matter to a business owner?

As a business owner, you may not need to know how to code in HTML, CSS, and JavaScript. However, it is important to have a basic understanding of each language so that you can make informed decisions when working with web designers and developers.
